Countershaft
Disassembly/Reassembly
1. Using a hydraulic press, press out the countershaftwhile supporting 4th gear.
NOTE: Place an attachment between the press andthe countershaft to prevent damage to the shaft.
CAUTION: Do not allow the countershaft to fall andhit the g.ound when pressed clear.

2. Assemble the parts on the countershaft as shownoetow.
NOTE;
. Lubricate all parts with ATF during assembly.. Before installing the O-rings, wrap the shaft splineswith tape to prevent damaging the O_rings.

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.
DISTANCE COLLAR, 28 mm
7. Afret selecting a new distance collar, recheck theclearance and make sure it is within tolerance.

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.
