It is important to
turn the pinion
while tightening the
bolts. If the ring
gear shim is too
thick, the gears will
lock after only light
1 of 1
Install the case cover and tighten the bolts in several
steps until the cover evenly touches the gear case.
Then, while rotating the pinion gear, tighten the
bolts to the specified torque in a crisscross pattern
in several steps.
TORQUE: 10 mm bolt: 49 N·m (5.0 kgf·m, 36 lbf·ft)
tightening.
8 mm bolt: 25 N·m (2.6 kgf·m, 19 lbf·ft)
Remove the oil filler cap.
Rotate the ring gear several times in both directions
of rotation.
Check the gear tooth contact pattern through the oil
filler hole.
The pattern is indicated by the Prussian Blue
applied to the pinion.
Contact is normal if the Prussian Blue is transferred
to the approximate center of each tooth, but slightly
to the heel side and to the flank side.
If the patterns are not correct, remove and change
the pinion gear shim with a suitable one.
Replace the pinion gear shim with a thicker one if
the contact pattern is too high, toward the face.
Replace the pinion gear shim with a thinner one if
the contact pattern is too low, toward the flank.
The pattern will shift about 0.5 1.0 mm (0.02
0.04 in) when the thickness of the shim is changed
by 0.12 mm (0.005 in).
Ring gear shims:
A: (thinnest): 1.64 mm (0.064 in)
D: (standard): 2.00 mm (0.079 in)
I: (thickest): 2.18 mm (0.086 in)
