9. Install the cover bolts and tighten them in
several steps until the cover evenly touches
the drive housing. Then while rotating the
pinion gear, tighten the bolts to the specified
torque in a crisscross pattern in several
steps.
TORQUE:
10mm bolt:45N.m
8mm bolt: 25N.m
10. Check that the gear assembly turns
smoothly without binding.
Remove the oil filler cap.
Install the special tool into the pinion joint, and set
the final drive assembly and tool in a vise.
Install the drive shaft into the final drive assembly
and hold it.
Set a horizontal type dial indicator on the ring gear
through the filler hole.
Turn the ring gear back and forth with the drive
shaft to read backlash.
STANDARD:0.05-0.25mm
SERVICE LIMIT:0.4mm
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:0.2mm
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 excessive, replace the ring gear
right shim with a thinner one.
If the backlash is small, replace the ring gear right
shim with a thicker one.
Backlash is changed by about 0.06mm when
thickness of the spacer is changed by 0.12mm.
