Two band type brakes, one on each steering clutchdrum, are used to stop the machine and giveassistance to the action of the steering clutch. Theoperation of each service brake is separate from theother.

The operation of both service brakes is the same.When lever (3) is pulled to the rear, rod (6) moves rod(2). Rod (2) moves levers (8 and 10) and rod (9). Rod(9) moves lever (11) which causes brake band (12) tomake contact with the steering clutch outer drum toslow or stop the machine and give assistance to thesteering of the machine.

When the lever is released, spring (1) returns the leverto its original position.

Adjusting screw (7) is used to adjust the pedal freetravel. Refer to D3C, D4C, and D5C Series III TractorPower Train Specifications, SENR5334, for the correctadjustment procedure.

Parking Brake OperationThe parking brake engages both the left and rightservice brakes. To engage the parking brakes, youmust move parking brake lever (4) DOWN, then pushthe service brake pedal FORWARD until the pedalstops moving.

To release the parking brake, move parking brake lever(4) UP and push the service brake pedal FORWARD.The pedal returns to its original position.

When the right lever is pulled, rod (10) moves forward.The movement of rod (10) causes cam assembly (9) tomove. When cam assembly (9) moves, it makescontact with roller (17) on valve (7). Roller (17) isfastened to stem (16). The movement of cam assembly(9) pushes stem (16) to the left. As stem (16) moves tothe left, it causes spring (15) to push spool (12) to theleft against the force of spring (11). As spool (12)moves to the left, spool (12) closes the openingbetween outlet (14) and drain (18). Further movementof spool (12) to the left opens a passage and allowspressure oil from the transmission hydraulic system toflow from inlet passage (13) to outlet passage (14).Outlet passage (14) is connected to tube assembly (8).Tube assembly (8) is connected to the steering clutchcylinder on the right side of the machine.

Tube assemblies (27) and (28) allow a small amount ofthe oil flowing to the steering clutch cylinder to returnto passage (18) in the control valve. This recirculatingof oil allows the steering clutch cylinder to warm upquicker and be more responsive in cold weather. The

amount of oil that is recirculated through tubeassemblies (27) and (28) is not enough to affect theoperation of the steering clutches. A 0.79 mm (.031 in)orifice in the elbow fitting on tube assemblies (27) and(28) at the steering clutch cylinder limits the return flow.

When either of the levers are released, the linkagereturns to its original position. The cam assemblymoves away from the roller and stem. Spring (11)pushes the spool to the right and stops the flow ofpressure oil to the steering clutch cylinder. After theinlet passage has been closed, the oil in the cylinder isallowed to flow to drain through passage (18) and hoseassembly (6). The return oil flows back into thereservoir in the transmission.

Steering and Brake Control[Hand Steer (Attachment)]

Location of Control Valves(1) Left side steering control valve. (7)Right side steering controlvalve.

NOTE: The combined hand steering arrangement isan attachment.

The steering and service brake operation is controlledby two levers and one pedal. The two levers controltheir respective steering clutch and service brake. Theleft lever is used for a left turn and the right lever isused for a right turn. Pulling the left or right lever until aslight pressure is felt releases the steering clutch andstarts to turn the machine. The remainder of levermovement engages the service brake. The amount offorce on the lever controls the amount of brakeapplication. The service brake pedal activates bothservice brakes and does not release the steeringclutches. Each steering clutch and brake has its ownoil supply for lubrication and cooling. All componentsget lubrication oil as the steering clutch turns and oil isthrown about (splash lubrication).

The oil supply for the steering clutch operation comesfrom the power train hydraulic system through hoseassembly (5) and a tube assembly to passage (13) inboth the right and left steering clutch control valves (7)and (1).

When the left lever is pulled, rod (4) moves forward.The movement of rod (4) causes cam assembly (3) tomove. When cam assembly (3) moves, it makescontact with roller (17) on valve (1). Roller (17) isfastened to stem (16). The movement of cam assembly(3) pushes stem (16) to the left. As stem (16) moves tothe left, it causes spring (15) to push spool (12) to theleft against the force of spring (11). As spool (12)moves to the left, spool (12) closes the openingbetween outlet (14) and drain (19). Further movementof spool (12) to the left opens a passage and allowspressure oil from the transmission hydraulic system toflow from inlet passage (13) to outlet passage (14).Outlet passage (14) is connected to tube assembly (2).Tube assembly (2) is connected to the steering clutchcylinder on the left side of the machine.


When the right pedal is pushed, rod (12) movesforward. The movement of rod (12) causes camassembly (11) to move. When cam assembly (11)moves, it makes contact with roller (19) on valve (9).Roller (19) is fastened to stem (18). The movement ofcam assembly (11) pushes stem (18) to the left. Asstem (18) moves to the left, it closes off passage (21)from passage (22). This stops the flow of supply oilfrom passage (21) in the right steering valve throughtube (8) to passage (15) in the left steering valve. Thismeans that the left steering clutch can not bedisengaged when the right one is.

As stem (18) moves to the left, it causes spring (17) topush spool (14) to the left against the force of spring(13). As spool (14) moves to the left, spool (14) closesthe opening between outlet (16) and drain (20). Furthermovement of spool (14) to the left opens a passageand allows pressure oil from the transmission hydraulicsystem to flow from inlet passage (15) to outletpassage (16). Outlet passage (16) is connected to tubeassembly (10). Tube assembly (10) is connected to thesteering clutch cylinder on the right side of themachine.

The bevel gear and pinion group is located betweenthe steering clutch compartments in the steering clutchcase. The bevel gear and pinion group is lubricated byoil thrown around inside the compartment by bevelgear (6).

Power from the transmission is sent through thetransfer gears to a drive shaft that is connected to yoke(1). Yoke (1) is connected by splines to bevel pinionshaft (5). Shims (2) adjust the amount of end play thatbevel pinion (5) has inside housing (4). Shims (3) adjustthe location of the heel of the teeth on bevel pinionshaft (5) in relation to the heel of the teeth on bevelgear (6). The teeth on bevel pinion shaft (5) areengaged with the teeth on bevel gear (6). Bevel gear(6) is fastened to bevel gear shaft (7) by bolts.

Bearing preload on bevel gear shaft (7) is adjusted withshims (9 and 11). Shims (9 and 11) also adjust theamount of free movement (backlash). Moving a smallamount of shims (9) to the right side decreases theamount of free movement. Moving a small amount ofshims (11) to the left side increases the amount of freemovement.

Couplings (8 and 12) are connected to the bevel gearshaft by splines that have a taper. Couplings (8 and12) are fastened to the steering clutch shaft by bolts.

The steering clutches and final drives transmit thepower from the bevel gear shaft to the track. There aretwo steering clutches and two final drives (one of eachfor each side). The final drives transmit power onlywhen the steering clutches are engaged.

The final drive cases are fastened to the bevel gearand steering clutch case. The final drive cases arereservoirs for oil for the final drives. As the componentsof the final drives turn, lubricant is thrown around theinside of the cases for lubrication of the components.

Shaft (1) is fastened to the coupling on the bevel gearshaft. Steering clutch driving drum (4) is connected toshaft (1) by splines that have a taper. Driving discs (6)have teeth on the inside diameter that are engagedwith teeth on steering clutch driving drum (4). Springs(5) force pressure plate assembly (3), driving discs (6)and driven discs (7) against steering clutch drivingdrum (4). The pressure against driven discs (7) causethem to turn with driving discs (6). Driven discs (7)have teeth on the outside diameter that connect withsplines on the inside of steering clutch outer drum(brake drum) (8). With the steering clutches engaged,the power is sent to the final drives.
