2. Reinstall mainshaft rear bearing outer race without shims.
3. Clean mating surfaces of clutch housing and transmission
case with solvent.
4. Install mainshaft and mainshaft front bearing outer race into
transmission case. Turn mainshaft while holding bearing outer
race so that bearings are properly seated.

5. Put straightedge [width must be more than 50 mm (1.97 in)] on
transmission case, and measure the distance from upper sur-
face of straightedge to surface of the bearing outer race using
a depth micrometer.
+Measure at three places on bearing outer race, and take
the average.
6. Determine dimension A to be used by the following equation.
Dimension A = Width of straightedge þ measured dis-
tance
7. Measure the distance from mating surface of clutch housing to
portion with which mainshaft front bearing outer race is to be
mated.
+Measure at three places on the portion, and take the aver-
age.
Dimension B = Measured distance
8. Determine dimension C to be used by the following equation.
Dimension ªCº=BþA
9. Determine total thickness of shims with SDS table as a guide.
Mainshaft bearing adjusting shim:
Refer to SDS, MT-134.
10. Install selected mainshaft bearing adjusting shim and main-
shaft bearing outer race.
11. Check total turning torque after assembly Ð Refer to
ªASSEMBLYº, MT-114.
