To replace input shaft (23) or bearings (24
and 25), remove particular bearing cone
from shaft using a press and suitable arbor.
If bearing (24) is replaced, remove bearing
cup from differential housing using a
If bearing (25) is replaced, remove oil seal
(26) and remove bearing cone (25) from
bearing cap (21) using a press and a
If output shaft bearing (35) is replaced,.
(see procedure a. step 6 preceding),
bearing cup (33) must be replaced. To do
this, remove bearing cup from power
divider cover (12) using a suitable puller
If pinion shaft support bearing is replaced,
(see 2-21.2 REPAIR), remove retaining ring
(36) and bearing race (35) from power
divider cover (12). Use a suitable puller to
remove bearing cup.
Dry cleaning solvent P-D-680 (safety or Stoddards solvent is potentially dangerous. Avoid repeated and
prolonged breathing of vapors and skin contact with the liquid. Do not use near open flame, arcing
equipment or other ignition sources. Always wear eye protection and protective clothing. The flash point
of P-D-680 is 100 to 138 deg. F (30 to 59 deg. C).
Death or serious injury could occur if compressed air is directed against the skin. Do not use compressed
air for cleaning or drying unless the pressure is/has been reduced to 30 psi (2.11 kg/cm2) or less. When
working with compressed air, always use chip guards eye protection and other personal protective
Clean all power divider components with dry cleaning solvent (item 10, Appendix B). Blow components
dry using compressed air.
Inspect all parts for notches, visible steps or grooves created by wear. Look for pitting or cracking along
gear contact lines. Scuffing, deformation, or discoloration are signs of excessive heat usually related to
low lubricant levels or improper lubrication practices.
(3) Before reusing a gear set, inspect teeth for signs of excessive wear. Check tooth contact pattern for
evidence of incorrect adjustment.
Inspect machined surfaces of cast or malleable parts. They must be free of cracks, scoring, and wear.
Look for elongation of drilled holes, wear on surfaces machined for bearing fits and nicks or burrs in
