9. How to select the correct thrust shim:-1) Compare the tapered roller bearing preload
you get with the thrust shim that was removed,
with the specified preload of 1.4 - 2.5 N.m(14 -- 26 kgfcm, 12-23lbtinl.-2) lf your measured tapered roller bearing preload
is less than specified. subtract yours from the
specified,
lf yours is more than specified, subtract the
specified from your measurement.
For example with a 2.17 mm (0.0854 in) thrust
shiml
@ specified 2.5 N.m (26 kgf.cm,23 lbiin)- you measure 0.6 N.m (6 kgf.cm,5 lbf.in)
1.9 N.m (20 kgicm, 18 tbt.in) tess
@ you measure 3.3 N.m (34 kgf.cm,30 lbf.in)- specified 2.5 N.m (26 kgncm,23 lbf.in)
0.8 N.m (8 kgf.cm,7lbt.in) more
Each shim size up or down from standard
makes about 0.3 - 0.4 N.. (3 - 4 kgf'cm,
2.6 - 3.5 lbf.in) difference in tapered roller bear-
ing preload.
In example @, your measured tapered roller
bearing preload was 1.9 N.m (20 kgf.cm,
18 lbf.in) less than standard so you need a
thrust shim five sizes thicker than standard {trythe 2.32 mm (0.0913 in) thrusr shim. and
recheck).
ln example @, your measurement was 0,8 N.m
{8 kgf.cm, 7 lbf.in) more than standard, so you
need a thrust shim two sizes thinner (try the
2.1'l mm {0.0831 in) thrust shim, and recheck).
