CAUTION: Do not reuse the thruEt shim and th€ 79.5
mm shim if the outer race was driven out.
NOTE:
a The bearing outer race and tapered roller bearing
should be reDlaced as a set.
a Inspect and adjust the tapered roller bearing preload
whenever the tapered roller bearing is replaced.
1 . Remove the oil seals from the transmission housing
and clutch housing (see page 15-13).
2. Remove the bearing outer race, the thrust shim, and
the 79.5 mm shim from the transmission housino.

7. lf the tapered roller bearing preload is not within the
standard, select the 79.5 mm shim from the follow-
ing table which will give the tapered roller bearing
preload closest to the standard mean value o{ 2.50
N.m (25.5 kgt.cm, 22 lbf.in).
NOTE: Changing the 79.5 mm shim to the next size
will increase or decrease tapered roller bearing
preload about O.3-0.4 N.m (3-4 kgl.cm,
2.6 - 3.5 lbf.in).

8. Recheck the tapered roller bearing preload.
9. How to select the correct 79.5 mm shim:
1) Compare the tapered roller bearing preload you
get with the 79.5 mm shim that was removed
with the soecified mean Dreload of 2.50 N'm
(25.5 kgf .cm, 22 lbf.in).- 2l ll vour measured tapered roller bearing preload
is less than specified, subtract your's from the
specitied.
lf vour's is more than specitied, subtract the
soecified from vour measurement.
For example with a 1.38 mm {0.0543 in) shim:
@ specified 2.50 N.m (25.5 kgf.cm, 22 lbl.in)- you measure 0.54 N.m (5.5 kg{.cm, 5lbl.in}
2.0 N.m (20 kgf.cm, 18lbf.in) less
@you measure 3.29 N.m (33.5 kgI.cm, 29 lbt.in)- specified 2.50 N.m (25.5 kgf.cm, 22 lbf.in)
0.8 N.m (8 kgf.cm,7lbf.in) more
-3) Each shim size up or down from standard
makes about O.3-0.4 N.nt (3-4 kgf.cm,
2.6-3.5 lbl.in) difterence in tapered roller
bearing preload.
a In example @, your measured tapered roller
bearing preload was 2.O N.m (2O kgt.cm,
18 lbf in) less than standard so you need a
79.5 mm shim live sizes thicker than stan-
dard {try the 1.53 mm (O.0602 in) shim and
recheck).
a ln example @ your's was 0.8 N.m {8
kgf.cm,7lbf.in) more than standard. so
you need a thrust shim two sizes thinner (try
the 1 .32 mm (O.O52O in) shim and recheck).
1O. After adjusting the tapered roller bearing preload, as-
semble the transmission, and installthe lransmission
housing (see section 13).

27 N,m (2.8 kgt'm, 20 lbf.ft)
11. Rotate the difterential assembly in both directions
to seat the tapered roller bearings.
