Center Support





Disassembly

NOTICE: The piston return spring, snap ring or snap ring retainer from the low/reverse clutch side of the center support are not interchangeable with the forward clutch side of the center support. When disassembling the center support, be careful not to mix the components from the low/reverse clutch side with the forward clutch side of the center support. Failure to assemble the center support with the components in the correct side will result in damage to the center support, low/reverse or forward clutch.

1. NOTE: The low/reverse clutch piston in the center support is the side of the center support with the long legs.
Using the Center Support Piston Spring Compressor 307-630 and a press, compress the low/reverse clutch return spring and remove the snap ring and the snap ring retainer.






2. Remove the low/reverse clutch return spring.





3. Apply 483 kPa (70 psi) of air pressure to the low/reverse clutch piston port and remove the low/reverse clutch piston.





4. NOTE: The forward clutch piston in the center support is the side of the center support with the short legs.
Using the Center Support Piston Spring Compressor 307-630 and a press, compress the forward (1, 2, 3, 4) clutch return spring and remove the snap ring and the snap ring retainer.






5. Remove the return spring from the forward (1, 2, 3, 4) clutch piston.





6. Apply 483 kPa (70 psi) of air pressure to the forward (1, 2, 3, 4) clutch piston port and remove the forward (1, 2, 3, 4) clutch piston.

NOTICE: The piston return spring, snap ring or snap ring retainer from the low/reverse clutch side of the center support are not interchangeable with the forward clutch side of the center support. When assembling the center support, be careful not to mix the components from the low/reverse clutch side with the forward clutch side of the center support. Failure to assemble the center support with the components in the correct side will result in damage to the center support, low/reverse or forward clutch.

1. Clean and inspect the center support for damage. Install a new center support if necessary.

2. NOTE: The forward clutch piston in the center support is the side of the center support with the short legs.
Install the Low Reverse Piston Seal Protector 307-628/2 and the Low Reverse / 1-2-3-4 Piston Seal Protector 307-629 on the forward clutch piston side of the center support.






3. Lubricate the sealing surfaces of the forward (1, 2, 3, 4) clutch piston with petroleum jelly.





4. Position the forward (1, 2, 3, 4) clutch piston on Low Reverse Piston Seal Protector 307-628/2 and the Low Reverse / 1-2-3-4 Piston Seal Protector 307-629 and push it down into the center support.





5. Install the forward (1, 2, 3, 4) clutch piston return spring.





6. Using the Center Support Piston Spring Compressor 307-630 and a press, compress the forward (1, 2, 3, 4) clutch return spring and install the snap ring retainer and the snap ring.





7. Inspect the snap ring to be sure it is seated in the groove on the center support.





8. Turn the center support over and install the Low Reverse Piston Seal Protector 307-628/1 and 307-628/2 on the low/reverse piston side of the center support.





9. Lubricate the sealing surfaces of the low/reverse piston with petroleum jelly.





10. Position the low/reverse clutch piston on the Low Reverse Piston Seal Protector 307-628/1 and 307-628/2 and push it down into the center support.





11. Install the low/reverse piston return spring.





12. Using the Center Support Piston Spring Compressor 307-630 and a press, compress the low/reverse clutch return spring and install the snap ring retainer and the snap ring.





13. Inspect the snap ring to be sure it is seated in the groove on the center support.
