When testing and adjusting the transmission and power train, move the

machine to an area clear of obstructions, with safe exhaust ventilation

for the exhausts. Sudden movement of the machine or release of oil

under pressure can cause injury to persons on or near the machine. To

prevent possible injury, do the procedure that follows before testing and

adjusting the transmission and power train.


12/224

Personal injury can result from spring force released when removing

cap screws.

Internal spring force will be released when cylinder assembly cap screws

are removed causing injury.

Always restrain cover as cap screws are loosened.

Follow the established procedure in the Service Manual to service these

parts.

NOTICE

Care must be taken to ensure that fluids are contained during

performance of inspection, maintenance, testing, adjusting, and repair

of the machine. Be prepared to collect the fluid with suitable containers

before opening any compartment or disassembling any component

containing fluids.

Dispose of all fluids according to local regulations and mandates.

Before you begin the test, refer to Troubleshooting, "Machine Preparation forTroubleshooting".

and replace caps (6) .

11. Remove caps (6) for test ports (8) and (11). Install 1000 kPa (145 psi) pressure

gauges on test ports (8) and (11) .

12. Operate the engine at high idle with the transmission control in SECOND GEARFORWARD. Record the pressures from the gauges in Table 2. Remove the gauges

and replace caps (6) .

13. Remove caps (6) for test port (7). Install a 1000 kPa (145 psi) pressure gauge on test

14.

Operate the engine at high idle with the transmission control in the FIRSTREVERSE GEAR. Record the pressure from the gauge in Table 2. Remove the

gauge and replace caps (6) .

15. Compare Table 2 to Table 3. If the initial pressures are not within specifications, proceed to Step 11.

16. Loosen locknut (16) on adjuster (17). Also, loosen the locknut on the adjusterdirectly behind adjuster (23) .

17.

Adjust the pressure by turning adjustment screw (24). To lower the pressure, turnthe adjustment screw clockwise. The total range for the adjustment screw is 132 kPa(19 psi).

18. Tighten locknut (25) to 25 ± 4 N·m (18 ± 3 lb ft). Shift the transmission to

NEUTRAL for a minimum of 15 seconds. Select the gear that is specified in steps 7through 15. Check that the pressure value is within the specifications in table 3.

19. If the pressure cannot be adjusted within the acceptable limits with adjusting screw(25), stop the engine and remove the control manifold (9) in order to access the

selector spool. Remove the selector spool and adjust the number of shims that arerequired. Also, adjust the number of spacers that are required.

1. Continue the procedure until all the pressure taps have been checked.

2. Stop the engine. Remove the transmission valve and install the original 8E-9474 Cover .

3. Use new 9P-9150 Washers and install the control group on the transmission.Tighten the mounting bolts (4) to 30 ± 4 N·m (22 ± 3 lb ft).

4. Attach the wiring harness (3) and the manual modulation spool.

5. Install guard (1) and install the differential drive shaft.

Note: If the transmission clutch pressure is out of the specification, the most likely cause ofthe failure will be a failed modulation spring, debris in the control valve or a seal failure

within the transmission.

Para hacer pruebas y ajustes de la transmisión o del tren de fuerza,

mueva la máquina a una zona libre de obstrucciones y en la que se

puedan ventilar los gases de escape sin peligro. El movimiento repentino

de la máquina o la descarga de aceite bajo presión puede causar lesiones

al personal situado en la máquina o en sus alrededores. Para evitar

accidentes, haga el procedimiento siguiente antes de hacer pruebas y

ajustes de la transmisión o del tren de fuerza.

ATENCION Se debe tener cuidado para que no se derramen los fluidos al hacer la

inspección, el mantenimiento, las pruebas, los ajustes y las

reparaciones a la máquina. Tenga a mano los recipientes necesarios

para recoger el fluido antes de abrir cualquier compartimiento o

desarmar cualquier componente que contengan fluidos.

Descarte todos los fluidos de acuerdo a los reglamentos y mandatos
