7. It the tapered roller bearing preload is not within the
standard, select the 79.5 mm shim lrom the follow-
ing table which will give the tapered roller bea.ing
preload closest to the standard mean value of 2.50
N.m (25.5 kgJ.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-O.4 N.m (3-4 kgf.cm,

Recheck the tapered roller bearing preload.
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 specified mean preload of 2.50 N.m(25.5 kgf .cm. 22 lbf.inl.-2) lf your measured tapered roller bearing preload
is less than specified, subtract your's from the
soecified.
lf your's is more than specified, subtract the
specified from your measurement.
For example with a 1 .38 mm (O.O543 in) shim:
@ specified 2.50 N.m (25.5 kgf.cm, 22 lbf.in)- you measure 0.54 N.m (5.5 kgt.cm, 5lbt'in)
2.0 N.m {20 kgf.cm, 18lbt.in} less
@you measure 3.29 N.m {33.5 kgl.cm, 29 lbl.in)- specified 2.50 N.m {25.5 kgf.cm, 22 lbf.in)
0.8 N.m (8 kgf.cm, 7lbt.in) more
3) Each shim size uD or down from standard
makes about O.3-O.4 N.m (3-4 kgf.cm,
2.6-3.5 lbf.in) difJerence in tapered roller
bearing preload.
a In example @, your measured tapered roller
bearing preload was 2.O N.m (20 kgf'cm,
I 8 lbl.in) less than standard so you need a
79.5 mm shim five sizes thicker thsn stan-
dard {trv the 1.53 mm (0.0602 inl shim and
recheck).
a In example @ your's was O.8 N.m (8
kgf.cm, 7 lbJ.in) more than standard, so
you need a thrust shim two sizes thinner (try
the 1.32 mm (0.0520 in) shim and recheck).
After adjusting the tapered .oller bearing preload, as-
semble the transmission, and installthe transmission
housing {see section 13).
