Reverse Clutch Disassembly and Reassembly
Disassembly





1. Remove reverse clutch drum with bearing (1) from oil pump body.
2. Remove sun gear input flange (2) with thrust washer (3) installed by removing retainer ring (4).
3. Remove friction plates "F", separator plates"S" and cushion plate "C" in the following order.
F -> S -> F -> S -> C





4. Remove reverse clutch return spring by removing snap ring (1), using special tool and hydraulic press (2).
Special Tool (A): 09926-96010

NOTE: To prevent deformation of spring seat, it is recommended to compress spring seat until claw section of snap ring is free.

5. Mount reverse clutch drum with bearing (2) to oil pump body (3).
6. Remove reverse clutch piston (1) by blowing compressed air (400 - 800 kPa, 4 - 8 kgf/cm2, 57 - 113 psi) through oil hole section (4).





7. Remove two O-rings from piston.

NOTE: Never reuse removed O-rings.

Reassembly
1. Apply A/T fluid to new O-rings.
2. Install them to reverse clutch piston (1).





3. Press reverse clutch piston (1) into reverse clutch drum with bearing (2) with cup side up.

NOTE: Do not twist or deviate O-rings during installation.

4. Place reverse clutch return spring onto reverse clutch piston.





5. Install snap ring (1), using special tool and hydraulic press (2).
Special Tool (A): 09926-96010

NOTE: To prevent spring seat deformation, be sure to keep clearance of 1 - 2 mm between return spring seat and snap ring.

6. Install cushion plate "C", separator plates "S" and friction plates "F" in the following order.
C -> S -> F -> S -> F

NOTE: Make sure that flat end section of plate faces toward piston side.





7. Install sun gear input flange (1) with retainer ring (2).
8. Measure piston stroke.
9. Remove reverse clutch from oil pump body.
10. Remove sun gear input flange by removing retainer ring.





11. Install snap ring (2) to reverse clutch drum with bearing (1).
12. Apply A/T fluid to input shaft rear thrust roller bearing (1).
