MANUAL TRANSMISSION AND DIFFERENTIAL
E: INSPECTION
Disassembled parts should be washed with water
first and then inspected carefully.
1) Bearing
Replace the bearings in the following cases.
• Bearing wear, rusting or damage
• If the bearing does not rotate smoothly or an ab-
normal noise is emitted when turning.
• When the bearing has other defects
2) Bushing (each gear)
Replace the bushing in following cases.
• When gear sliding surfaces are damaged or ex-
cessively worn.
3) Gear
Replace gears in the following cases.
• When gear teeth are damaged or excessively
worn.
• If the contact area of the baulk ring is damaged.
• If the inner face of the gear is worn.
4) Baulk ring, synchro cone
Replace the baulk ring and synchro cone in follow-
ing cases:
• Baulk ring wear, rusting or damage
5) Shifting insert key
Replace the shifting insert key if deformed, exces-
sively worn or defective in any way.
Driven Gear Assembly
F: ADJUSTMENT
1) Measure the length "H" from the transmission
case and oil pump cover mating surface, to the end
face of the ball bearing.
(A) Transmission case
(B) Ball bearing
(C) Driven gear ASSY
2) Using the following calculation, calculate the
thickness of the driven gear assembly washer.
T = H – {5.8±0.05 mm (0.23±0.002 in)} – {0.1 — 0.3
mm (0.0039 — 0.0118 in)}

3) Select 0 to 3 washers from the following table,
and adjust to the backlash that is closest to the
standard value.
