4. 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 adjust the starting loads (preload).
Bearing preload
128 ～ 166 N
{13
～
17 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.
NOTE:
When backlash is 0 (zero), the bevel gear of the
differential may be stuck closely to the drive shaft.
(2) Adjust the shims (2) to obtain B – A = 0.15 mm
NOTE:
Refer to the paragraph of the transmission for the gear
contact pattern of the pinion and ring gear when
adjusting.
