1. INSTALL NEW O-RINGS ON PISTON
2. INSTALL PISTON IN FRONT OF CLUTCH DRUM
Press the piston into the housing with the cup side up (check ball down).
Be careful not to damage the O-rings.
3. INSTALL TWENTY PISTON RETURN SPRINGS, SPRING RETAINER AND SNAP RING IN PLACE
4. COMPRESS RETURN SPRINGS AND INSTALL SNAP RING
(a) Place SST on the spring retainer, and compress the springs with a shop press.
SST 09350-20013 (09369-20040)
(b) Install the snap ring with a screwdriver.
5. INSTALL DISCS AND PLATES WITHOUT ASSEMBLING
THINNER SNAP RING
(a) Do not assemble the thinner snap ring yet.
(b) Using low-pressure compressed air, blow all excess ATF from the discs. For measurement of the clutch pack, install all plates and discs (temporarily without thinner snap ring).
CAUTION: High-pressure air will damage the discs.
Install in order: Plate-disc-plate-disc-plate-disc-plate (no snap ring)-disc
6. CHECK PISTON STROKE OF FRONT CLUTCH
(a) Install the rear clutch hub and the outer snap ring.
(b) Install the front clutch drum onto the overdrive case. With a dial indicator, measure the stroke applying and releasing the compressed air (4 — 8 kg/cmJ, 57 — 114 psi or 392 - 785 kPa) as shown.
Standard piston stroke: 1.40 — 2.24 mm
If not within specification, select a proper plate.
NOTE: There are two different thickness.
7. INSTALL THINNER SNAP RING IN CLUTCH DRUM
(a) Remove the outer snap ring, rear clutch hub and disc to allow installation of the thinner snap ring.
(b) Compress and lower the snap ring into the groove by hand. Check that the ends of the snap ring are not aligned with one of the cutouts.
8. INSTALL DISC
9. INSTALL INNER THRUST BEARING AND RACES
IMPORTANT: Coat parts with petroleum jelly to hold them in place.
Install the inner race, needle bearing and outer race. Press them into place.
NOTE: Face the lip of race toward the front of the clutch body.
10. INSTALL FRONT CLUTCH HUB
Align the disc lugs with the hub teeth. Make sure the hub meshes with all discs and is fully inserted.
11. INSTALL REAR CLUTCH HUB AND OUTER SNAP RING
Check that the snap ring ends are not aligned with one of the cutouts.
NOTE: Note the position of the inner thrust bearing and races, and keep them together until assembly.
12. KEEP THRUST BEARINGS AND RACES TOGETHER
