Important operations
Check operation of one-way clutch
Hold the OD direct clutch drum and turn the input shaft.
The input shaft should turn freely clockwise and should lock
counterclockwise.
(1): Free
(2): Lock
1. OD direct clutch assembly
Remove OD direct clutch assembly from OD planetary
gear.
2. Thrust bearing
Then remove thrust bearing with the race from OD direct
clutch drum.
Check piston stroke of OD direct clutch (C-O)
Place the oil pump onto the torque conver ter, and then
place the OD direct clutch assembly onto the oil pump.
Use a dial indicator, measure the OD direct clutch piston
stroke applying and releasing the compressed air (4– 8 kg/

14. Snap ring
Install snap ring.
Check piston stroke of OD direct clutch (C-0).
Place the oil pump onto the torque converter, and then
place the OD direct clutch assembly onto the oil pump.
Using a dial indicator, measure the OD direct clutch piston
stroke by applying and releasing the compressed air (4– 8
kg/cm
2, 57– 114 psi or 392– 785 kPa) as shown.
If the piston stroke is not within specification, replace the
disc and recheck the piston stroke.
If the piston stroke is non standard, select another flange.
There are six flange sizes.mm (in.)
