Caution: Refer to Compressed Air Should Not Exceed 98 kPa (14 psi) Caution in the Preface section.




1. Install the direct clutch and thrust needle roller bearing on the oil pump.
2. Using a dial indicator, measure the direct clutch piston stroke while applying and releasing compressed air.

If the stroke is non-standard, inspect the discs, the plates, and the flange.

Specifications
The piston stroke is 0.4-0.8 mm (0.016-0.031 in).




3. Using a screwdriver, remove the snap ring.



4. Remove the flange (1), 2 discs (2), and 2 plates (3).



5. Place DT 46451  (1) and DT 46453  (2) on the direct clutch return spring and compress.

Caution: Do not depress the direct clutch piston return spring lower than 1-2 mm (0.039-0.078 in.) beyond the snap ring groove. This will prevent the direct clutch piston return spring from becoming distorted.

Note: Do not expand the snap ring excessively.

6. Using a snap ring expander, remove the snap ring.



7. Remove the direct clutch return spring.



8. Install the direct clutch on the oil pump.

Caution: Refer to Compressed Air Should Not Exceed 98 kPa (14 psi) Caution in the Preface section.

Note: Air pressure may cause the pistons to jump-out. When removing the piston, hold it with your hand using a waste cloth.

Note: Do not splash ATF when air-blowing.

9. Apply compressed air to the oil pump to remove the direct clutch piston.

When the piston can not be removed as it is slanted, either blow the air again with the protruding side pushed or remove the piston using needle nose pliers with vinyl tape on the tip.




10. Using a small screwdriver, remove the O-ring (1) from the direct clutch piston.



11. Remove the O-ring (1) from the input shaft.




Note: Do not expand the ring ends excessively.

12. Remove the seal rings (1) from the input shaft.
