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

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).

Operational Check
Set the parking brake and block the rear wheels.
Raise the front of the vehicle, and support it with
safety stands in the proper locations (see section 1).
With the engine off, shift the transmission into lstgear,
Rotate either front wheel bv hand and check that
the other wheel rotates in the opposite direction.
lf the opposite tront wheel does not rotste, or if voucannot spin the front wheels at all, the limited slip
differential is faulty and should be roplaced.
Rotating Torque Check
Setting parking brake and block the rear wheels.
Raise the front of the vehicle, and support it with
safety stands in proper locations (see section 1).
With the engine off, shift the transmission into
Neutral.
Measure the rotating torque with a beam-type
torquo wrench in the direction shown, Rotate the
torque wrench morg than two complete turns and
take the maximum reading.
Shift the transmission into 1st gear and measure
the rotating torque again.
Calculate the rotating torque:

Tapered Roller Bearing Preload Adjustment
lf any of the items listed below were replaced, the
tapered roller bearing preload must be adjusted,
. Transmission housing
. Clutch housing
. Limited slip diffsrential assembly
. Tapored roller bearing and bearing outer race. Thrust shim
. 79,5 mm shim
Remove the bearing outer race, the thrust shim, and
the 79,5 mm shim from the transmission housing.
Replace the thrust shim and the 79.5 mm shim if
they were dsmaged when the bearing outer race
was driven out.
First try the same size 79.5 mm shim that was
removeo.
HOUSING
Install the thrust shim and only one 79.5 mm shim
in the transmission housing, then drive in the bear-
Ing our€r race.
Noto these items during rassembly:
. Install the bearing outer race squarely.. Check that there is no clearance between the
bearing outer race, shims and transmission
housing,
With the mainshatt and countershaft removed,
installthe differential assemblv. Assemble the clutch
housing and transmission housing without a sealing
a9ent, and torque the case bolts.
8 x 1.25 mm
27 N.m (2.8 kgf.m, 20 lM.ft)
Rotate the differential assemblv in both directions
to seat the tapered roller bearings.
Measur€ the tapered roller bearing preload of the dif-
ferential assembly in both directions with the special
tool and a toroue wrench.
