Forward and Reverse Clutch Assemble

Forward and Reverse Clutch Assemble

^ Tools Required
- DT 46451 (DW240-020) Brake/Clutch Spring Compressor
- DT 46452 (DW240-030) Forward Clutch Adapter
- DT 46520 (DW240-120) Measuring Terminal





1. Coat a new O-ring (1) with automatic transmission fluid (ATF) and install it to the intermediate shaft sub-assembly.





2. Coat a new O-ring (1) with ATF, and install it to the forward clutch drum.





3. Important:
Do not damage the O-ring and lip seal of forward clutch drum.

Coat the forward clutch drum with ATF, install the forward clutch drum.





4. Important:
Do not damage the lip seal of forward clutch return spring.

Coat the forward clutch piston with ATF, install the forward clutch piston.





5. Important:
Do not damage the lip seal of forward clutch return spring.

Install the forward clutch return spring and clutch balancer.





6. Place the DT 46451 (1) and DT 46452 (2) on the clutch balancer and compress the piston return spring.

7. Important:
Do not expand the snap ring excessively.

Using a snap ring expander, install the snap ring.





8. Install the 3 plates (2), 3 discs (3), and the flange (1) in order 2-3-2-3-2-3-1.





9. Using a screwdriver, install the snap ring.
10. Check that the end gap of the snap ring is not aligned with one of the cutouts.





11. Install the plate (2), 2 discs (3), and 2 flanges (1) in order 1-3-2-3-1.





12. Using a screwdriver, install the snap ring.
13. Check that the end gap of the snap ring is not aligned with one of the cutouts.





14. Notice:
Refer to Compressed Air Should Not Exceed 98 kPa (14 psi) Notice.

Install the forward and reverse clutch and thrust needle roller bearing on the transaxle rear cover.
15. Using a dial indicator, measure the reverse clutch pack clearance while applying and releasing 392 kPa (57 psi) of compressed air.
^ If the pack clearance is less than the limit of pack clearance, parts may have been assembled incorrectly, so check and reassemble again.If the pack clearance is non-standard, select another flange.

The pack clearance is 0.4 - 1 mm (0.0157 - 0.0394 inch).
^ There are 4 flanges in different thickness.
^ The number 1 flange thickness is 3 mm (0.118 inch).
^ The number 2 flange thickness is 3.2 mm (0.126 inch).
^ The number 3 flange thickness is 3.4 mm (0.134 inch).
^ The number 4 flange thickness is 3.6 mm (0.142 inch).





16. Install the forward and reverse clutch and thrust needle roller bearing on the transaxle rear cover.
17. Using a dial indicator and the DT 46464 (1), measure the forward clutch pack clearance while applying and releasing 392 kPa (57 psi) of compressed air.
^ The forward and reverse clutch will come out as you apply the compressed air. Therefore, while the checking is being done, press on the input shaft of the forward and reverse clutch using stamping machine or alike so that the pressure is not applied on the forward and reverse clutch.
^ If the pack clearance is less than the limit of pack clearance, parts may have been assembled incorrectly, so check and reassemble again.If the pack clearance is non-standard, select another flange.

The pack clearance is 1.1 - 1.5 mm (0.043 - 0.059 inch).

^ There are 4 flanges in different thickness.
^ The number 1 flange thickness is 3 mm (0.118 inch).
^ The number 2 flange thickness is 3.2 mm (0.126 inch).
^ The number 3 flange thickness is 3.4 mm (0.134 inch).
^ The number 4 flange thickness is 3.6 mm (0.142 inch).
