15. REAR WHEEL/AXLE/SUSPENSION
DRIVING MECHANISM MXU 300/250
Remove the oil cap and a horizontal type
dial indicator on the ring gear through the
filler hole.
Turn the ring gear back and forth to read
backlash.
Standard:
0.05 0.25 mm (0.002 0.01 in)
Service limit: 0.4 mm (0.16 in)
Remove the dial indicator. Turn the ring
gear 120° and measure backlash.
Repeat this procedure once more.
Compare the difference of the three
measurements.
Service limit: 0.2 mm (0.08 in)
If the difference in measurements exceeds
the service limit, it indicates that the bearing
is not installed squarely, or the case is
deformed.
Inspect the bearings and case.
If the backlash is too small, replace the ring
gear right side spacer with a thicker one.
Backlash is changed by about 0.03 mm
(0.0012 in) when thickness of the spacer is
changed by 0.06 mm (0.0024 in).
Three shims (from A to C) are available
in thickness increments of 0.03 mm
(0.0012 in).
Right ring gear shims:
A: 1.53 mm (0.0612 in)
B: 1.5 mm (0.06 in)
C: 1.47 mm (0.0588 in)
Left ring gear shims: Left Ring Gear Shim Right Ring Gear Shim
A: 1.53 mm (0.0612 in)
B: 1.5 mm (0.06 in)
C: 1.47 mm (0.0588 in)
