Note these items:
. The bearing outer race and tapered roller bearingshould be replaced as a set.. lnspect and adjust the tapered roller bearing preload
whenever the tapered roller bearing is replaced.
'1. Remove the oil seals from the transmission housingand clutch housing (see page j3-43).
2. Drive the bearing outer race and thrust shim out ofthe transmission housing, or remove the bearingouter race and 75 mm shim from the clutch housingby heating the clutch housing to about 212"F(100"C) with a heat gun. Do not reuse the thrustshim if the outer race was driven out.

1. Remove the bearing outer race and thrust shim
from the transmission housing (see page 13-40)'
NOTE:
. Do not reuse the thrust shim if the bearing outer
race was driven out.
. Let the transmission cool to room temperature il
the bearing outer race was removed by heating
the clutch housing.
2. Do not use more than one thrust shim to adjust the
tapered bearing preload. First try the same size
thrust shim that was removed. There are no shims
used on the clutch housing side

After installing the thrust shim, install the bearing
outer race in the transmission housing (see page

With the mainshaft and countershaft removed,
install the differential assembly, and torque the

NOTE: lt is not necessary to use sealing agent be-
tween the housings.

Select the proper 78 mm shim from the chan by
using the formula below.
Shim S€lection Formula:
From the measurements you made in steps 4 and 5:-1. Add distance @ (step 5) to distance @ (step 4).
-2. From this number. subtract 0.93 (which is the
midpoint of the flex range of the clutch housing
bearing spring washer).
-3. Take this number and compare it to the avail-
able shim sizes in the chart.
(For example)
A: 2.39 2.61
+ Bi O.22 - 0.93
= 2.61= 1.68
Try the 1.68 mm (0.0661 in) shim.

sion housing as shown.
Note these items:
. Use liquid gasket (P/N 08718 - 0001 or 08718 -
0003).
. Remove the dirty fluid from the sealing surface.
. Seal the entire circumterence of the bolt holes to
prevent fluid leakage.
. lf 20 minutes have passed after applying liquid
gasket, reapply it and assemble the housings.
a Allow it to cure at least 20 minutes after assem-
bly betore filling the transmission with MTF.
Install the 14 x 20 mm dowel pins.
Set the stopper ring as shown. Place the transmis-
