TRANSMISSION REPAIR (Continued).
Cleaning solvent (Appendix D, Item 54) is
both toxic and flammable. Keep off skin.
Use only in a well-ventilated area and
avoid prolonged breathing of vapors.
Keep away from open flames.
(n) Check needle bearing assembly (64).
Wash and flush the needle bearing
assembly thoroughly with cleaning solvent
(Appendix D, Item 54). Dry it, and lubricate
with transmission oil (Appendix D, Item
38). Replace the freewheel race only and
rotate the bearing while pressing upon the
freewheel race. If there is no roughness or
binding, the needle bearing assembly may
be left in the stator and cam assembly and
reused. Do not mistake dirt or grit for a
damaged needle bearing. Reclean and
reoil the needle bearing if dirt is suspected.
Check the needle bearing end of freewheel
race for smooth finish. Replace the
freewheel race if the bearing end is
scratched or contains chatter marks.
NOTE
If it is necessary to repair the stator
assembly (60), remove needle bearing
assembly (64) before starting repair
procedure.
(o) If needle bearing assembly (64) needs
replacement, follow steps (p) through (r)
below.
CAUTION
Do not scratch or nick any stator bores.
Do not attempt to disassemble the
stator and cam assembly, unless part
replacement is necessary.
(p) If the needle bearing must be replaced,
remove it carefully to avoid nicking the
aluminum bore in which it is held.
(q) Place a new bearing assembly, thrust race
first, into the aluminum bore of the stator.
Using bearing installer, install the thrust
bearing.
CAUTION
Apply the load only to the outer shell of
the bearing during installation.
(r) Drive the bearing assembly into the stator
until the top of the outer shell is 0.025-
0.035 inch (0.64-0.89 mm) above the
shoulder in the side plate. The installing
tool will seat on the stator area surrounding
the bearing when the bearing is properly
installed.
(s) Remove needle bearing (64), bearing race
(65), and remove roller bearing (66) with
converter pump hub roller bearing remover
and installer from converter pump hub
(67). Remove sealring (68).
