threaded holes in the flange and rotate the jackscrews to
force the flange
off
the transmission case. Position the
transmission with the input shaft up, then remove the
flange from the transmission case .
9. Remove the output shaft (A, Fig
ure
9) assembly from
the transmission case and set aside for disassembly.
10. The input shaft (B, Fi
gur
e 9) and intermediate shaft
(C) assemblies must be removed together. Proceed as fol-
lows:
a. Insert a suitably sized bolt or rod through the hole in
the rear
of
the transmission that supports the inter-
mediate shaft (
figure
10).

b. Carefully drive out the intermediate shaft while re-
moving the intermediate and input shaft assemblies
from the transmission case.
I!. Using a large screwdriver, pry out the oil seal in the
transmission case. Be careful not to damage the case or
the adjacent bearing race.
12. Using a large screwdriver, pry out the oil seal in the
transmission mounting flange. Be careful not to damage
the case or the adjacent bearing race.
13.
If
inspection indicates additional disassembly is nec-
essary, refer to the following sections.

shaft
I. Check the gear teeth for excessive wear, corrosion and
mechanical damage. Check the teeth for galling, chips,
cracks, missing pieces, distortion or discoloration from
overheating. Replace the input shaft if the gears are dam-
aged.
2. Inspect the input shaft bearings
(Ffgure
II)
and seal
surfaces for excessive wear, grooves, metal transfer and
discoloration from overheating. Use a press 10 remove
damaged bearings and to install new bearings.
NOTE
Shims behind the outer bearing race in the
mountingflange determine bearingpreload
for
the input shaft hearings. Save the shims
and reinstall them
if
reusing the original
parts.
3. Inspect the input shaft bearing outer races in the trans-
mission case (A, Figure 12) and mounting flange (A,
rig
-
ur
e 13). If either race is damaged or excessively worn,
remove it using a suitable puller.
