17. Select case cover using the following procedure.
a. Measure distance between case cover fitting surface and
mainshaft rear bearing outer race.
Clearance ªCº between the end of case cover and
main shaft rear bearing outer race (Main shaft end
play):
0 - 0.1 mm (0 - 0.004 in)
b. Select case cover so that clearance ªCº will be specified clear-
ance.
Case cover:
Refer to SDS MT-89.
18. Install O-ring and case cover on transmission case.
IApply recommended sealant to mating surface of trans-
mission case.
