4. Measure the clearance between the 2nd gear andthe 28 mm distance collar with a feeler gauge.
NOTE: Take measurements in at least three places.and use the average as the actuar ctearance.
STANDAFD: 0.10 - 0.18 mm {0.004 - 0.002 inl
lf the clearance is out of tolerance. remove the 2gmm distance collar and measure the width.
Select and install a new distance collar, thenrecheck.

After the parts are assembled, hold countershaft 1st
gear and turn the park gear in the direction shown
to be sure it turns freely. Also make sure the park
gear does not turn in the opposite direction.

Backlash lnspection
1. Place differential assembly on V-blocks and install
both axles.
Check backlash of both pinion gears
Standard {Now): 0.05 - 0.15 mm {0.002 - 0.006 in)
lf backlash is out of tolerance, replace the differen-
tial carrier.
Bearing Replacement
NOTE: Check bearings for wear and rough rotation. lf
bearings are OK, removal is not necessary.
1, Remove bearings using a bearing puller.
