Reassembly
1. Reassembly of drive pinion
(1) Be careful about the direction of the oil seal.
(Position the seal lip to the oil side and fit under
pressure 2 mm inward from the case end.)
(2) Tighten the nut and measure the starting load
(preload).
Bearing preload
98 – 137 N
(10 – 14 kgf)
NOTE: Measure the bearing starting load at the
spline. Lock the nut at the time of
measurement.
2. Backlash of bevel gear (differential)
After assembling the drive pinion, adjust the backlash
of the bevel gear in the following procedure.
(1) Place the differential ass’y into the case and adjust
the backlash to 0 (zero) with shims (1).
NOTE: When backlash is 0 (zero), the bevel gear of
the differential may be sticked closely to
the drive shaft, leaving gap between the
bearing and case. Adjust in such a case
increasing the shims.
(2) Take out the differential ass’y from the case again,
fit a shim (1) so as to obtain the specified backlash,
and install the differential ass’y.
(3) Adjust the shims (2) to obtain A – B = 0 mm
(4) Measure the backlash with a dial gauge.
Backlash of bevel gear (mm)
Standard assembling value Repair value
0.1 – 0.15 More than 0.3
NOTE: Refer to the paragraph of the transmission
for the gear contact pattern of the pinion
and ring gear when adjusting.
