mm

PLASTIGAUGE STRIP

• If the plastigauge measures within the standard,

go to step 14.

• If the plastigauge does not measure within the

standard, continue with step 12.

1 2. Select the proper 65 mm shim based on the follow-

ing table.

• If the measurement was less than 0.18 mm, in-

stall a thinner shim.

• If the measurement was more than 0.229 mm,

install a thicker shim.

65 mm shim

1 3. After installing a thinner or thicker shim, be sure to

recheck the measurement with plastigauge.
• After installing a thinner shim:

If the measured value is less than 0.18 mm, select

the next thinner shim, and recheck.

If the new value is more than 0.229 mm, the

selected shim is OK.

• After installing a thicker shim:

If the measured value is more than 0.229 mm,

select the next thicker shim, and recheck.

If the new value is less than 0.18 mm, take the

shim you chose at the step 12.

14. Install the washer, thrust needle bearing, 65 mm

shim, 112 mm shim, clutch plate, clutch disc, and

spring plate. Position the 65 mm shim with the

thickness stamp mark facing up.

If any of the items listed below are replaced, the bearing

preload must be adjusted.

• TRANSMISSION HOUSING

• CLUTCH HOUSING

• DIFFERENTIAL

• TAPERED ROLLER BEARING and OUTER RACE

• 75 mm THRUST SHIM

• 90 mm WASHER

1 . Remove the bearing outer race and 75 mm thrust

shim from the transmission housing by prying up

on the bearing outer race or by heating the housing

to about 212°F (100°C).

CAUTION: Do not reuse the thrust shim if the

outer race was pried out.

NOTE:

• If the outer race was removed by heating the

case, let the transmission cool to room tempera-

ture before adjusting the bearing preload.

• Do not heat the transmission housing in excess

of 212°F (100°C).

• Replace the bearing with a new one whenever

the outer race is replaced.

• Repeat on the clutch side.
