Bearing Outer Race Replacement
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.

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).

Transfer Assembly
Reassembly
Note these items during reassembly:. While reassembling the transfer assembly:- Check and adjust the transfer gear tooth contact.- Measure and adjust the transfer gear backlash.- Check and adjust the tapered roller bearing start-Ing rorque.
. Coat all parts with MTF during reassembly.. Replace the tapered roller bearing and the bearingouter race as a set if either part is replaced.. Replace the transfer drive gear and the transfer dri-ven gear shaft as a set if either part is replaced,
Outline of Assembly
1.Select the 35 mm thrust shim.
Perform this procedure if the transler driven gear
shaft or the tapered roller bearing on the transferdriven gear shaft is replaced.
Preassemble the parts to check and adjust transfergear backlash and transfer gear tooth contact.
Disassemble the parts, then assemble the transferdriven gear shaft and its related parts.
4. Measure and adjust the staning torque of the trans-fer driven gear shaft tapered roller bearing.
5. Assemble the transfer shaft and jts related parts.
6. Measure and adjust the total starting torque.
35 mm Thrust Shim Seleqtion
1. Select the 35 mm thrust shim if the transfer drivengear shaft or the tapered roller bearing on the trans-fer driven gear shaft is replaced.
Calculate the thickness of the 35 mm thrust shimusing the formula below.
