7. Inspect output shaft: See Figure 2.119.
7a. Visually check the end splines (for the
front and rear drive shafts)
7b. Visually check the spline that engages the
bull gear.
7c. Check the surfaces that ride in the ball
bearings for galling or fretting. Damage to
this part of the gear also dictates the need
to replace the corresponding bearing.
8. Inspect input shaft: See Figure 2.120.
8a. Visually check:
*The end spline (CVT mounting)
*The reverse pinion (machined onto shaft)
*The spline that engages the Low pinion.
*The spline that engages the high pinion.
*The surfaces that ride in the ball bearings
and seals for galling, fretting, and
scratches.
8b. Damage to the shaft dictates the need to
replace the corresponding bearing or gear
that rides on that part of the shaft.
8c. Check the high gear pinion and low gear
pinion for damage.
NOTE: The gear teeth are unlikely to be hurt
except in cases of extreme contamination, corro-
sion or foreign object damage. In any of these
cases the transfer case is likely unfeasible to
repair.
8d. Check the hardened flat washer. It should
be .060” (1.52mm) thick.
