    STEERING
    Model 7002 - Header Tank

    The purpose of a header tank is to allow for the steering gear fluid to expand and contract due to temperature variations.

    The header tank can be used on a manual-filled sustem as well as on an auto-filled sustem. The capacity of the tank is one quart (one liter). It is available with or without sight glass and breather.

    It is recommended to have this tank installed above the highest helm pump onboard ship. In addition, a manual-filled system should be installed with a breather or an auto-filled system should be sealed with a vent line going from the header to the main tank.

    Model 7018 Sail Boats Lock Valve

    Many sail boast skippers prefer mechanical steering because they can feel the pressure on the rudder when they are sailing and that will, therefore give them a much better feel of wind and weather conditions.

    In order to satisfy the discriminating sailor, Kobelt developed the 7018 remote mounted lock valve. This valve fulfils all the wishes of a sail boat captain.

    A regular good hydraulic steering system is equipped with a lock valve behind the hydraulic helm pump. This lock valve prevents any hydraulic pressure feedback going to the steering wheel.

    Putting the remote lock valve 7018 in the open position will require the skipper to keep this hand on the wheel to affect a course and the pressure of the rudder can be felt at the steering wheel.

    By putting a remote lock valve into the closed position the rudder will remain where it was left without having to hold on to the wheel, the hydraulic oil is locked in the system and will maintain the given direction.

    Model - 7020 Safety and Bypass Valve

    The purpose of this valve is to safeguard against damage to the steering gear or rudder from hydraulic shocks and over pressure. This valve also incorporates the function of a bypass value. This is very useful when bleeding the system or rotating the rudder by hand. The safety and bypass value is installed near the steering cylinder between the port and starboard lines. The design of the valve allows plumbing directly into lines without the necessity of pipe tees.

    Model 7029 Outboard Motor Tie Bar

    Kobelt Manufacturing has developed unique tie bars for multiple outboard motors mechanical interconnection. The purpose is to synchronize the movement of two or more outboard motors so the steering angle stays the same.

    These tie bars are available in any lengths up to 5 ft. For other sizes and applications please contact our sales department. We specially manufacture the end threads 4" long so they may be cut as required by the installer. Constructed entirely of bronze and stainless steel, these bars are highly compatible with the salt water environment.

    Model 7030 Side Mount Steering Cylinder For Outboard Motors

    The 7030 Steering Cylinder is intended to be attached to the tilt tube which is equipped with 7/8" NF thread. The 7030 cylinder rod passes through the tilt tube and is screwed on the 7/8" NF thread then locked in position with a setscrew to prevent it from rotating. The regular link supplied by the outboard motor makers is then attached between the tiller and arm and the hole provided at the end of the cylinder rod to steer the outboard motor.

    Kobelt Manufacturing also manufactures helm pumps. Ideally, the helm pump for the application is the 7031 which is a fixed displacement pump and provides 2 cu. In. of fluid volume per turn. If more volume at less turns is required, our 7003 and 7005 helm pump can be employed.

    The 7030 side mount cylinder is constructed totally in bronze and stainless steel with a hard chromed piston rod and will provide years of trouble-free service.

    Model 7031 Helm Pump

    The Kobelt 7031 Helm Pump is constructed totally in bronze and stainless steel except for the bearings, pistons, and pintol which are made of hardened and ground steel. Because of this, it can be installed anywhere on the boat. It is a true marine product and is covered by the standard Kobelt warranty.

    The 7031 Helm Pump is a fixed displacement pump and produces 2 cu.in. per turn. It is rated for 1000 psi maximum operating pressure

     

    Model 7032 Outboard Motor Front Mount, Steering Cylinder,
    Cylinder

    Kobelt Manufacturing, with its vast variety of bronze and stainless steel marine control and steering gear components, has been asked on many occasions to manufacture a steering gear for outboard motors. These requests came simply because most of the outboard steering devices in the market are made either in aluminum, zinc or plastic and do not seem to stand up to the marine environment too well.

    Kobelt Manufacturing took a whole new look at outboard steering devices and developed the new 7032 cylinder which is shorter in length, easier to install and service in the field, and also provides for twin outboard motor configuration with a connection point for a tie bar, This unit will provide years of trouble-free service.

    Model 7033 Outboard Motor
    Steering Cylinder

    The Model 7033 outboard motor steering cylinder was designed to be attached directly onto the late model outboard motor brackets. The draglink provided is used to connect the cylinder rod onto the motor tiller arm with stainless steel shoulder bolts.

    The swiveling arrangement between the cylinder and the mounting bracket allows the cylinder to be raised or lowered to suit the height of the tiller arm. The cylinder is of extreme heavy-duty construction, made entirely of bronze and stainless steel and will handle 300 horsepower motors.

    Since the cylinder bolts directly onto the outboard motor bracket, the cylinder itself is supported by the motor and swivels with the motor when the motor is raised or lowered and therefore takes all the stress away on the draglink since the draglink now is primarily only rotating the motor.

    This cylinder is ideally suited for all heavy-duty outboard motor applications. The standard stroke is 7-1/2". Upon special request, any stroke length is available. The cylinder can also be ordered epoxy-coated.

    Model 7035 Tilt Up Steering

    Due to the simplified construction, and selection of superb materials, this pump will outlast any other product on the market.

    The Kobelt design eliminates the universal joint - instead the whole helm pump moves with the wheel when rotated up or down.

    The tilting mechanism provides 5 locking positions at 10o increments with a total rotation of 50o. This unit is available with helm pumps Model No. 7031 or Model No. 7004.
    The 7031 has 2 cu.in. or (7031-X) 2.6 cu.in. volume per turn and our Model No. 7004, which has a nominal volume of 3.4 or (7004-X) 4.5 cu.in. per turn

    Model - 7100 HEAVY DUTY CYLINDER
     

    The 7100 Steering cylinder has a 10” ID with a 5” stainless steel hard-chromed piston rod. It is also available with either bronze or steel castings with the cylinder tube being made of pre-honed steel tubing and spherical bearings at both ends of the cylinder.

    The rear-type trunion mount allows for extremely easy installation since the pre-drilled base plate provides the flat and solid fittings to readily install this cylinder in the steering gear compartment.

    A foundation plate is required to withstand the strain imposed by the cylinder of approximately 300,000 pounds (150 tons).

    All the cylinders manufactured by Kobelt from 4” up, are of the unbalanced type and therefore require the minimum of two per steering system. Grease fittings are provided on both ends to lubricate the spherical bearings.

    Model 7143 Non-Drain Back Valve

    This valve is intended to be used in power steering systems. Its purpose is to retain all of the hydraulic fluid in the steering system itself when the power-driven hydraulic pumps are not operational, to allow the use of the helm pump without loss of hydraulic fluid.

    All hydraulic valves, because of their mechanical fit, lose fluid in various amounts and this would consequently cause the hydraulic fluid to drain from the highest level to the lowest level. In most cases, the helm pump is located in the wheelhouse which is above the main hydraulic tank, the oil will eventually drain back to the main tank and leave the system dry. The 7143 valve, however, will retain all of the fluid in the system and will therefore, in an emergency condition, allow the helm pump to be used almost indefinitely. If this unit is used on a 7147 or 7148 Kobelt Power Assist Unit, it is important to have a buffer system in order to get these units to shift to manual mode.

    If the 7143 is installed on the servo steering system, all helm pumps must have a non-vented plug. The header tank must also be sealed (non-vented). The return line from the header tank must be opened far enough to allow all the pressure from the hydraulic system to vent via the header tank back to the main tank. If flow control is too widely open the header tank will be pressurized and could cause possible damage to side glass and cause leakage between the tank and the cover. A minimum of oil should pass through the flow controls, but sufficient enough to allow the pressure to drop off in the system.

    Model 7144 - Single Solendoid Adaptor Base

    The 7144 is equipped with a flow control to provide an adjustable speed for rudder positioning. It also provides flow control for an auto-fill system. This small flow control can be adjusted to provide a very small volume of oil to be delivered to the header tank. The header tank, in turn, will require an overflow line to the main tank.

    The basic purpose for the adaptor base is to provide control over the rudder in either direction. Its maximum flow capacity is six gallons per minute and it can be equipped with either an open or a closed center Soft Shift solenoid valve.

    If more than one valve is used in a single system, closed centre solenoid valves are required on both. It is also recommended to have volume compensated pumps in the steering gear system to reduce heat and for better economy.

    Model 7145 Dual Solenoid Adaptor Base

    The purpose of the 7145 is to provide either two or three speeds for steering gear. On a steering system having an autopilot, full power follow-up, both hydraulic and electronic, it becomes essential to have more than one rudder speed.

    The 7145 with closed centre spools can provide two or three speed operations and also an auto-fill line in the header tank. By energizing one solenoid valve and setting the flow control for the appropriate speed, the rudder can be controlled by an full-power follow-up operation and by setting the flow control of the second solenoid, the rudder can be controlled at a slower speed by an autopilot.

     

    If both valves are open at the same time a third speed can be obtained, for jogging the rudder hardover to hardover. If open centre spool valves are used, only two speeds can be obtained. The oil will circulate through both valves at all times, but the maximum flow-through capacity will not exceed the needle-valve setting.

    The maximum flow capacity with both valves fully open is 12 gallons per minute. Volume compensated pumps are recommended.

    When more than one spool value is used in a system, they should all be closed center. We recommend using soft shift solenoid values for a quieter and smoother system.

    Model 7147 Full Power Follow-Up Steering Cylinder

    The 7147 full power follow-up steering system is primarily designed for workboats up to 80' and pleasure crafts up to 120' in length.

     

    Upgrading and existing manual hydraulic system to power steering is easy, since most of the system components are already installed on the vessel. The full power follow-up valve and servo incorporated into the cylinder eliminates the need for any steering linkage. The helmsman can now effortlessly operate the rudder with complete control.

    The Kobelt power steering system will handle rudder torques up to 5,000 ft. lbs (695 kgms). This unit is available in 7.5", 10" and 12" strokes. The 7147 can also be used in dual cylinder installations, by adding one cylinder and two hoses. Made of high quality bronze and stainless steel, the cylinders are virtually unaffected by the harsh marine environment and will provide years of trouble free service.

    Note: The foot for the 7147 is different than the 7050.

    Model 7148 Power Follow-Up

    If performance, simplicity and durability are important, this unit incorporates it all. Castings are made in silicon die-cast bronze with all stainless steel hardware to provide years of trouble-free service.

    This basic unit provides the same function on a marine craft as power steering does on a car. Turning the rudder by hand on larger and high speed vessels can present quite a physical effort. This unit, in conjunction with a hydraulic power source (pressure compensated pump), will provide fingertip control over the rudder.

     

    The solenoid attached to this unit can be used for either autopilot or jog lever remote control. A patented, flexible linkage arrangement between the follow-up unit and the rudder stock is installed to make up for any differences in motion.

    In case of hydraulic pressure failure, a changeover valve will direct the hydraulic fluid from the helm pump directly into the steering cylinders, enabling the ship's personnel to steer the boat in a manual mode.

    Solenoid valves installed on a steering system must be of the soft shift type. If multiple solenoids are used, they must be of the closed centre type.

    Model 7165 Compact Single Axis Joy Stick

    designed to control positioning devices for either on/off or infinite positioning. It can be equipped with either 2 micro switches or a potentiometer. The microswitches would give an on/off signal in either direction and the potentiometer would provide infinite control in both directions. This unit is available with spring return or detent and or friction. The potentiometer is available in either 1k or 5k and the entire unit is constructed in bronze and stainless steel. Its compact design allows the unit to be installed in virtually any small space.

    Model 7166 Compact Electronic Helm

    This unit is basically designed for electronic steering gear applications. It could, however, be used for many other purposes.
    It provides 2 2/3 turns from HO to HO and is equipped with a single potentiometer (Standard 1k pot).

    The shaft is machined with a standard 3/4" taper. This unit is manufactured in bronze and stainless steel and will provide years of trouble free service. The wheel to be used with this helm should be limited to a maximum of 18 inches (450 mm) for optimum performance.

    Note: an oversized steering wheel can damage this unit which is an electronic helm.

    Model 7167 2-Axis Electronic Joystick

    This unit is ideally suited for many marine and industrial applications such as bow thruster, steering gear and winch control as well as the control of hydraulic servo devices such as waterjets and outboard drives and throttle controls.

    It is compact and all components are made in bronze and stainless steel which will give years of trouble-free service.

    The potentiometer can be customer-installed or factory supplied. Various potentiometers and gear ratios are available to suit customer requirements. The unit is available in either spring return to mid-position or neutral detent. In neutral detent style, the lever can be left in any position.

    This unit lends itself extremely well for manual-override control for dynamic positioning of drill ships and diving vessels.

    Model 7168 Rudder Angle Feedback Unit

    This small version of a rudder angle feedback unit with its all bronze and stainless steel construction is available with one of two potentiometers.
    Its compact design and watertight construction will allow it to be installed in very tight quarters. Because of the non-corrosive construction, it is intended for a saltwater environment.

    Its purposes are to give rudder angle position or feedback signal to either an autopilot, angle indicator or electronic steering components.

     

    Model 7169 Electro Controller (Multipurpose)

    Operation of the lever moves the potentiometer and also contacts a make and brake microswitch in the mid-position.

    The potentiometer can be customer installed or factory supplied. Various potentiometers and gear ratios are available to suit customer requirements. The unit is available in either spring return to mid-position or neutral detent. In neutral detent style the lever can be left in any position.

    This unit is ideally suited for many marine and industrial applications such as bow thruster, steering gear and winch control as well as the control of hydraulic servo devices and even C.P. propulsion and throttle controls.

    Model 7170 Jog Lever

    This Jog lever is used in power hydraulic steering systems. The operator can maneuver the boat by simply jogging the lever for port or starboard movement.

    The unit is operated by two internal microswitches. Its watertight construction in bronze and stainless steel will ensure years of trouble free operation.

    The jog lever will override the steering wheel, however it will not cause any interference should the power hydraulics fail.

    Various finishes are available and the unit can be ordered with the cable running straight out or down. The cable configuration can easily be changed in the field.

    Model 7171 Full Follow-Up Control Lever

    The model 7171 is manufactured in all bronze and stainless steel, and is suited for installation anywhere on the ship. Its watertight construction will not allow seaspray to enter the unit.

    This device is a full follow-up rudder control. It is equipped with a detent in mid handle position; the straight ahead position. Moving the control to either port or starboard will cause the rudder to follow proportionately. In order to complete a system of this nature, a feedback device connected with a link to the rudder stock, such as our Model 7174, and an electronic interface will then give the operator complete control over the rudder. This is possible at all times since the control and the 7171 correspond with the rudder position.

    The 7171 is available with 2 Microswitches (1 per side), 2 potentiometers and 2 Trim Pots. The 7171 is also available as a jog lever with 2 Microswitches per side.

    Model 7172 Electronic Helm

    The Model 7172's basic purpose is to provide an electronic signal to the hydraulic steering gear for positioning of the rudder.

    Normally the 7172 is equipped with two potentiometers.

    The first will be used with our 7173 interface to send the rudder to either port or starboard. This gives precise rudder positioning, when used in conjunction with our 7168 or 7174 feed-back unit.

    The second potentiometer can be used to indicate rudder demand, the actual rudder position is fed back via the 7168 or 7174 to separate rudder angle indicator.

    The construction of our 7172 is all bronze and stainless steel and it is designed to give years of trouble-free service. Straight ahead detent is provided. The wheel has approximately three turns from hardover to hardover.

    The heavy duty construction allows the helmsman to hang on to the wheel in the roughest of weather without causing any damage to this unit.

    Model 7173-K Electronic Full Follow-Up Amplifier

    This unit is designed to accept the command signal from our Models 7167, 7169, 7171, 7172 and 7176 and co- ordinates the desired rudder position with our feedback unit Models 7168 or 7174.

    Models 7144, 7145 and 7148 are equipped with solenoid valves and can be activated by the Model 7173-K and will disperse hydraulic fluid to the hydraulic steering system to maintain the desired position.

    This device can be located anywhere aboard ship, even in the steering compartment, since its watertight and non-corrosive materials will not affect the electronics internally.

    The Model 7173-K Amplifier is a multi-optional driver board (12 or 24-Volt DC) that can control:

    Single steering system

    Dual speed steering system

    Two independent steering systems controlled by the same controller
    (This is ideal for catamaran steering because of its electronic tie bar.)

    Two independent hydraulic systems (i.e. steering and bucket control)

    This unit can be changed in the field. See manual.

    Model 7174 Rudder Angle Feed Back

    This unit is designed to be mechanically connected to the rudder stock. Its purpose is to feed back the rudder angle position to such items as the Auto Pilot, Full Follow Up Control systems and Rudder Angle Indicator.

    This unit is available with up to 3 Potentiometers, 3 Trim Pots and 2 Microswitches. It is constructed of bronze and stainless steel and will withstand vibration and corrosion for years.

    Model 7175 - Rudder Indicator

    The 7175 rudder indicator system will continuously monitor and indicate the position of your rudder.

    Whether you are manoeuvring, power steering or changing course, an accurate readout of the rudder postion will be displayed on a three colour, three inch display.

    The basic system consists of a 7175-MA Master Station and Kobelt 7168 Follow-Up Unit.

    Up to five additional 'repeater stations' can be installed by using the 7175-SA repeater.

    Both the master and repeater have a backlit translucent display with an optional dimmer and are waterproof on the front face.

     

    Model 7178 Panoramic Rudder Angle Indicator

    This bronze and stainless steel unit was specially designed give an optimal view of the rudder position signal from all areas within the wheelhouse.

    Equipped with a manual dimmer for the background illumination, the internal parts are accessible through a removable plate at the bottom of the unit. The illuminating light bulbs have a nominal life cycle of 30,000 hours. The unit is available in either 12- or 24-Volt DC options.

    MODEL 7195 Stacked FFU Lever Controller

    This dual stacked lever controller provides full follow up control of the dual steering gear systems commonly found on Push Boats. These vessels are a regular site on the Mississippi and adjoining river systems. One steering gear controls the steering rudders aft of the propellers and the other the flanking rudders forward of the propellers.

    The 7195 is intended for use with electric over hydraulic steering systems. To complete the systems, a 7173-K steering amplifier, steering (directional control) solenoid valve and Rudder feedback unit complete with potentiometers and limit switches such as our 7174-A is required for each gear. For systems with more than one station, a transfer box and station selector switches at each station are also required.

    The 7195 is available with up to two potentiometers per handle and each handle includes a friction tensioning device. The top handle (usually for the flanking rudder system) also comes with a center detent. The standard handle length is 16” (18” from center of hub) but can be made shorter or longer on request. The controller (with the exception of switches and potentiometers) is constructed entirely of die cast bronze complemented by stainless steel hardware for longevity in a marine environment.

    Operating the FFU lever controller generates a control signal to the steering amplifier, which in turn activates the steering solenoid, allowing the hydraulic steering gear to move in the desired direction. When the handle is released, the FFU lever stays in that position (does not spring back to center) and the steering gear will continue to move (“FOLLOWING UP”) until it reaches that predetermined position, at which point the amplifier will de-activate the solenoid and the steering gear stops moving and holds that position.

    The position of the rudders is proportional to the position of the FFU lever. Returning the lever to midship will cause the steering gear to “FOLLOW UP” to the midship position and stop and stay there until the next signal is given.

    CAUTION Before selecting FFU mode of steering control at a given station, align the steering lever with the position of the rudder. The lever must be within a few degrees of the rudder before selecting FFU mode at that station. The helm order indicator and rudder angle indicator must match before selecting FFU mode control.

    Model 7196 Two Speed Jog Lever

    This jog lever is a robust all metal cast bronze construction with stainless steel hardware to provide a long service life in a marine environment. With the watertight shaft seal and above panel sealed mounting, this unit can be located anywhere on the boat.

    The 4” (100 mm) long handle is a spring-return to center device to provide Non Follow-Up two speed steering control. Move the handle 30 degrees to engage the first micro switch to activate a solenoid valve and continue to move the handle another 25 degrees to engage the second micro switch to activate another solenoid valve. One solenoid valve would provide a normal rudder speed for course holding, two solenoid valves provide a fast rudder speed for maneuvering.

    Releasing the handle will cause the steering gear to stop. The handle springs back to center and the steering gear stays in the last position and does not move until you operate the jog lever. For a trouble free long life operation, an internal extension spring was incorporated rather than the normal torsional spring.

    The jog lever has four 10A micro switches wired N.O. (normally open). See instructions for full details.

    Two steering (directional control) solenoid valves are required, a rudder feedback unit with limits switches is recommend, but a steering amplifier is not required.

    The two-speed jog lever can be used in other marine applications or industrial installations that require rising, lowering, or left and right motion control. For example, move the handle to the first micro switch to activate a power unit and continue to move the handle to activate the motion control.

    Model 7197 Single FFU / Jog Combination Controller

    This dual mode combination single lever is Kobelt’s latest development in providing Full Follow Up rudder control with a jog steering as the secondary control. The 7197 is intended for electric over hydraulic steering systems. To complete the systems, a 7173-K steering amplifier, steering (directional control) solenoid valve and rudder feedback unit complete with potentiometers and limit switches such as our 7174-A is required. For systems with more than one station, a transfer box and station selector switches at each station are also required.

    The 7197 is available with up to three potentiometers and one pair of limit switches. Optional items such as the 7180 (2-1/8” diameter) indicator or mode selector switches and/or station transfer switches can be added. The controller (with the exception of switches and potentiometers) is constructed entirely of die cast bronze complemented by stainless steel hardware for longevity in a marine environment.

    Operating the FFU lever controller generates a control signal to the steering amplifier, which in turn activates the steering solenoid, allowing the hydraulic steering gear to move in the desired direction. When the handle is released, the FFU lever stays in that position (does not spring back to center) and the steering gear will continue to move (“FOLLOWING UP”) until it reaches that predetermined position, at which point the amplifier will de-activate the solenoid and the steering gear stops moving and holds at that position.

    The position of the rudders is proportional to the position of the FFU lever. Returning the lever to midship will cause the steering gear to “FOLLOW UP” to the midship position and stop and stay there until the next command is given.

    In the event a problem occurs with the steering amplifier or the rudder feed back unit, you can switch to jog steering mode by pushing the lever hard over against the enclosed spring. Releasing the handle will cause the lever to spring back about five degrees; the steering gear stops and stays in position and does not move until you operate the jog lever again.

    CAUTION:
    Before selecting FFU mode of steering control at a given station, align the steering lever with the position of the rudder . The lever must be within a few degrees of the rudder before selecting FFU mode at that station. The helm order indicator and rudder angle indicator must match before selecting FFU mode control.

    Model 7198 Dual lever FFU/Jog Combination Controller

    This dual mode combination dual lever is an extension of our 7197 single lever controller. Each lever provides Full Follow-Up rudder control with a jog steering as the secondary control for each steering gear. The 7198 is intended for electric over hydraulic steering systems with two steering gears that are hydraulically and mechanically independent of each other. To complete the system, 7173-K steering amplifier, steering (directional control) solenoid valves and rudder feedback unit complete with potentiometers and limit switches, are required for each gear. For systems with more than one station, a transfer box and station selector switches at each station are also required.

    The 7198 system can provide synchronized rudder control with one lever (right hand side by default) and/or independent rudder control with each lever controlling its own steering gear.

    In the event a problem occurs with the steering amplifier or the rudder feed back unit, you can switch mode to jog steering and then push the lever hard over against the enclosed spring on either end. Releasing the handle will cause the lever to spring back about five degrees; the steering gear stops stays in that position until you operate the jog lever again.

    Each control unit of the 7198 can accommodate with up to three potentiometers and two limit switches. With ample space between the two levers, optional items such as mode selector switches for selection of synchronized or independently operated rudders, and/or station transfer switches can be added. The controller (with the exception of switches and potentiometers) is constructed entirely of die cast bronze complemented by stainless steel hardware for longevity in the marine environment.

    Model 7201 Autopilot Hydraulic Pump
    In a manual hydraulic steering system, a source of hydraulic pressure is required to make the autopilot operational. The 7201 is specifically designed for this purpose.

    It is available with either 12 or 24 volt DC motors and is intended for intermittent use only. The pump itself could be used on a continuous basis, but the motor would overheat if the pump is set on a high volume and relatively high pressure.

    The maximum amperage that the motor can handle on an intermittent basis is approximately 30 amps for a 12 volt motor and 15 amps for a 24 volt motor. We do, however, recommend that the motor should not draw any more than 16 amps for the 12 volt motor and 8 amps for the 24 volt motor.

    The table below indicates the capabilities of the motor. The pump can also be used on a more powerful motor to produce one gallon per minute on a relatively continuous basis. Adjustable safety valves for both port and starboard are provided and also flow control screws provide adjustment for the variable delivery from 40 to 250 cubic inches per minute. (Upon special request, the volume could be increased to 300 cubic inches per minute.) The lock valve fitted on the pump is to prevent hydraulic feedback in the steering system.

    Both pump and motor are equipped with ball bearings. The pump is made of silicon bronze, stainless steel hardware with hardened steel pistons and wear plate.

    To get this pump with relays, order the 7201-PR.

    Model 7201-PR Autopilot Pump Plus Relays

    The Kobelt 7201 Auto Pilot Hydraulic Pump is available with inhoused PC board. The relays on the board are capable of handling 30 amp current for either rotation. A fuse is provided for maximum motor load at 30 amp. This is based on the 12 volt motor. For a 24 volt motor the maximum load is 15 amp and the fuse is installed accordingly.

    The center terminal block is for the directional control circuit and the other blocks are for the power in and power out to the motor. (The motor leads are internal in the housing).

    Please read the 7201 AutoPilot Pump page to learn about it.

    Tiller Arms

    The Tiller Arms serves a very important function. It converts the linear motion on a steering cylinder into the rotary motion of the rudder stock.

    It is, therefore, very important that the Tiller Arm is of sufficient strength to withstand all the pounding, mechanical and hydraulic force imposed on it under severe conditions.

    Stock Tiller Arms are available from Kobelt in many shapes and sizes. We also manufacture custom made Tiller Arms, especially for bigger applications, where we are working to specific rudder stock dimensions and larger cylinders.

    When machining a Split Tiller Arm, it is important that shims are placed between the two halves. This will allow the clamping pressures to be applied to the rudder stock. The keyways must also be machined on size and parallel to the shaft. No lost motion should exist between the Tiller Arm and the rudder stock.

    This is especially important when a Full Power Follow-Up Hydraulic system is installed such as the Model 7148. It is recommended to periodically check all bolts pertaining to the Tiller Arm and Steering Cylinder to ensure that they are tight and that all components are in good working order.
