Repair For Components Parts (Part 2)
High Clutch
COMPONENTS
DISASSEMBLY
- Compress clutch springs and remove snap ring from spring retainer.
- Place clutch drum onto oil pump, and withdraw clutch piston with compressed air.
INSPECTION AND ASSEMBLY
1. Check clutch drive plate facing for wear or damage.
Standard drive plate thickness: 1.6 mm (0.063 in)
2. Check for wear on snap ring, weak or broken coil springs, and warped spring retainer.
3. Lubricate clutch drum bushing, and install inner seal and piston seal as illustrated. Be careful not to stretch seals during installation.
- Never assemble clutch dry; always lubricate its components thoroughly.
- Always install piston seal in direction shown .
4. Assemble piston, being careful not to allow seal to kink or become damaged during installation.
Use Tool, which does not damage lip seal, to make sure the lip seal goes into place.
- After installing piston, turn piston by hand to ensure that there is no binding.
5. Install clutch springs.
6. Reinstall snap ring. Be sure snap ring is properly seated.
7. Install driven plates, drive plates, and secure with snap ring.
8. Measure clearance between retaining plate and snap ring. Always measure the existing minimum clearance, since snap ring is a wave type.
Specified clearance:
Standard 1.4 - 1.8 mm (0.055 - 0.071 in)
Allowable limit 2.6 mm (0.102 in)
Retaining Plate Of High Clutch:
9. Check high clutch operation using compressed air.
Low Clutch
COMPONENTS
- Use Tool to remove the clutch spring snap ring.
- Service procedures for low clutch are essentially the same as those for high clutch, with the following exception:
Specified clearance between retaining plate and snap ring:
Standard 0.5 - 0.8 mm (0.020 - 0.031 in)
Allowable limit 2.0 mm (0.079 in)
Retaining Plate Of Low Clutch:
- After assembly, check the operation of clutch
Reverse Clutch
COMPONENTS
Service procedures for reverse clutch are essentially the same as those for high clutch, with the following exception:
- Remove reverse clutch piston.
Specified clearance between retaining plate and snap ring:
Standard 0.5 - 0.8 mm (0.020 - 0.031 in)
Allowable limit 1.2 mm (0.047 in)
- After assembly, check the operation of clutch.
Low & Reverse Brake
Retaining Plate Of Reverse Clutch:
COMPONENTS
INSPECTION
- Examine low and reverse brake for damaged clutch drive plate facing and worn snap ring.
- Check drive plate facing for wear or damage; if necessary, replace.
Specified clearance between retaining plate and snap ring:
Retaining Plate Of Low And Reverse Brake:
Standard 1.2 - 1.6 mm (0.047 - 0.063 in)
Allowable limit 3.0 mm (0.118 in)
Adjust clearance using driven plate at part A first.
If clearance exceeds specified value after using 5.0 mm (0.197 in) retaining plate (31667-23X08), remove driven plate and install 3.4 mm (0.134 in) retaining plate (31667-23X00). Readjust clearance by using another suitable retaining plate.
Brake Band and Band Servo
COMPONENTS
INSPECTION
- Inspect band friction material for wear. If cracked chipped or burnt spots are apparent, replace the band.
- Check band servo components for wear and scoring.
Planetary Carrier
INSPECTION
- Check clearance between pinion washer and planetary carrier with a feeler gauge.
Standard clearance:
Front carrier 0.15 - 0.70 mm (0.0059 - 0.0276 in)
Rear carrier 0.20 - 0.70 mm (0.0079 - 0.0276 in)
Replace if the clearance exceeds 0.80 mm (0.0315 in).
- Check planetary gear sets and bearings for damaged or worn gears.
Bearing Retainer and Output Shaft
INSPECTION
Measure clearance between seal ring and ring groove.
Standard clearance: 0.10 - 0.25 mm (0.0039 - 0.0098 in)
Wear limit: 0.25 mm (0.0098 in)
Converter Housing and Transmission Case
BEARING OUTER RACE
- Reduction pinion gear front bearing outer race
- Differential side bearing outer race
OIL SEAL
- Torque converter oil seal
- Differential side oil seal
Final Drive
COMPONENTS
DISASSEMBLY
1. Remove final gear.
2. Drive out pinion mate shaft lock pin and draw out pinion mate shaft.
3. Remove governor shaft drive gear.
4. Drive out differential side bearing outer race and inner cone.
INSPECTION
1. Check mating surface of differential case, side gears and pinion mate gears. Replace as required.
2. Check clearance between side gear and differential case with washer following the procedure below.
a. Set Tool and dial gauge on side gear.
b. Move side gear up and down to measure dial gauge deflection. Always measure gauge deflection on both side gears.
Clearance between side gear and differential case with washer:
0.1 - 0.2 mm (0.004 - 0.008 in)
c. If clearance exceeds the specified value, check for wear and replace necessary parts.
3. Check tapered roller bearings for wear, scratches, pitching or flaking.
ASSEMBLY
1. Install the side gear and thrust washer in the differential case.
2. Install the pinion mate gear and thrust washer in the differential case while rotating them
3. Insert pinion mate shaft.
When inserting, be careful not to damage pinion mate washers.
4. Measure clearance between side gear and pinion mate gear, referring to "Inspection". If necessary, adjust.
Side gear to pinion mate clearance: 0.1 - 0.2 mm (0.004 - 0.008 in)
Side gear thrust washer: Refer to S.D.S.
5. Install pinion mate shaft lock pin using a punch.
Make sure that lock pin is flush with case.
6. Install governor shaft drive gear.
7. Press on differential side bearing inner cone and outer race.
8. Install final gear.
