GEAR-SIDE 9U4831 - Caterpillar

Torque Converter Turbine Hub End Play Check
1. Remove the transmission and torque converter from the vehicle as a unit.2. Remove the torque converter from the transmission.3. Put the flywheel side of the torque converter face down on blocks.
Torque Converter
(1) Turbine hub.4. Make an adjustment to 6V2169 Converter Checking Fixture so that the legs will go inside of turbine hub (1).5. Install the fixture into hub (1) and adjust the fixture until the points on the legs are below the hub.6. Install the 8S2328 Dial Indicator Group so that the stylus is in contact with the fixture. Set the dial indicator to 0.
Turbine Hub End Play Check7. Move the fixture up against the dial indicator with two screw drivers as shown.8. The end play must not be more than 1.65 mm (.065 in.). If the end play is more than 1.65 mm (.065 in.), the torque converter must be replaced.Transmission Shift Blockout Adjustment
Transmission Shift Blockout Adjustment
(1) Lever. (2) Bolt. (3) Locknut. (4) Lug.(4 Speed)
1. Place shift lever (1) into fourth gear.2. Turn adjustment bolt (2) until it touches the shift lug (4).3. Back bolt (2) out one turn and tighten locknut (3).(3 Speed)
1. Place shift lever (1) in NEUTRAL.2. Turn adjustment bolt (2) until it touches the shift lug (4).3. Back bolt (2) out one turn and tighten locknut (3).Shuttle Control Adjustment Procedure
Forward/Reverse Control
(1) Forward/reverse hand control. (2) Neutral lock.
Transmission Control Valve
(3) Control lever. (4) Adjustable rod.1. Put forward/reverse hand control lever (1) in neutral position and engage neutral lock (2).2. Put control lever (3) on transmission control valve in the neutral position (center detent position).3. Adjust rod end (4) until it slips easily into hole in lever (3).4. Attach rod end (4) and tighten all locknuts.Transfer Box
Transfer Box.
(1) Transfer box (drive group). (2) Ball check spring. (3) Ball check. (4) Ball check seat. (5) Drive flange. (6) Transfer drive shaft. (7) Transfer drive group gaskets: shim as required. (8) Clutch pack. (9) Transfer drive gear. (10) Solenoid. (11) Solenoid valve. (12) Solenoid valve spring. (13) Solenoid valve spool.The illustration shown is for a Series II transfer box. The internal arrangement is similar and the operation is the same.The drive input enters the transfer box at gear (9). When the operator activates the electric switch on the side console, solenoid (10) is powered and pushes solenoid valve spool (13) down against spring (12).When spool (13) moves far enough, a passage is opened that allows oil under pressure to flow to drive shaft (6). The oil flows through shaft (6) to engage clutch pack (8). With the clutch pack engaged, the drive input at gear (9) is then transmitted through clutch pack (8), shaft (6), to output drive flange (5).Troubleshooting The Four Wheel Drive System
To prevent possible injury, do the procedure that follows before testing and adjusting the differential, rear axle and brakes:
1. Move the machine to a smooth horizontal location. Move away from working machines and personnel. Stop the backhoe loader engine.2. Permit only one operator on the machine.
