Part 3 of 3
U/D GEAR UNIT REMOVAL
1. CHECK PISTON STROKE OF UNDERDRIVE CLUTCH
a. Set a dial indicator (long type pick or SST).
SST 09350-32014 (09351-32190)
b. While applying and releasing compressed air (392 - 785 kPa, 4 - 8 kgf/cm, 57 - 114 psi), measure the underdrive clutch piston stroke.
Piston stroke: 1.50 - 1.90 mm (0.0590 - 0.0748 inch)
If the piston stroke is non-standard, select another flange.
HINT: There are 4 different flange thicknesses.
Flange thickness:
2.04 mm (0.0803 inch)
2.20 mm (0.0866 inch)
2.40 mm (0.0945 inch)
2.50 mm (0.0984 inch)
2. REMOVE UNDERDRIVE CLUTCH DRUM AND ANTIRATTLE CLIP
3. CHECK PACK CLEARANCE OF UNDERDRIVE BRAKE
Using a dial indicator, measure the underdrive brake pack clearance.
Pack clearance (reference): 1.15 - 1.97 mm (0.0453 - 0.0776 inch)
If clearance is non-standard, check the disc.
4. REMOVE UNDERDRIVE BRAKE
a. Remove the 2 oil seal rings.
b. Using SST and press, press in the flange until the snap ring is free from the flange.
SST 09350-32014 (09351-32070)
c. Using a screwdriver, remove the snap ring.
d. Remove the flange, 3 plates and disc.
e. Remove the piston return spring.
f. Using low-pressure compressed air (98 kPa, 1 kgf/cm, 14 psi), pop out the brake piston into a rag.
g. Using a screwdriver, remove the 2 O-rings from the piston.
5. REMOVE FIRST AND REVERSE BRAKE PISTON
a. Using SST and a press, press in the return spring until the snap ring is free from the return spring.
b. Using snap ring pliers, remove the snap ring.
SST 09350-32014 (09351-32040)
c. Remove the return spring and snap ring.
d. Apply compressed air into the oil passage of the case to remove the piston.
HINT: Hold the piston so it is not slanted and blow with the gun slightly away from the oil hole.
e. If the piston does not pop out with compressed air, use needle-nose pliers to remove it.
f. Using a screwdriver, remove the 2 O-rings from the piston.
6. REMOVE PARKING LOCK PAWL
a. Remove the parking lock pawl stopper plate, torsion spring and spring guide.
b. Remove the bolt and pawl shaft clamp.
c. Remove the parking lock pawl shaft and lock pawl.
7. REMOVE PARKING LOCK SLEEVE
8. REMOVE CAM GUIDE BRACKET
Remove the cam guide bracket.
9. REMOVE 134 ACCUMULATOR PISTON AND SPRING
a. Remove the 3 bolts.
b. Using a torx wrench, remove the 6 screws. Remove the gallery cover and gasket.
c. Remove the 134 accumulator piston and spring.
10. REMOVE BEARING
Using SST, remove the bearing.
SST 09308-00010
11. REMOVE OIL TUBES
a. Remove the 3 oil tube clamps.
b. Using a screwdriver, remove the 2 oil tubes.
HINT: Tape the screwdriver tip before use.
12. REMOVE BEARING
a. Remove the bolt and retainer.
b. Using SST, remove the bearing.
