Drive System Service: Lubrication - Cub Cadet 6X4 Shop Handbook

DRIVE SYSTEM SERVICE: LUBRICATION

1. The universal joints in the drive shafts that con-
nect the transfer case to the front and rear differ-
entials are lubricated on assembly, and should
not need further lubrication in their normal ser-
vice life. See Figure 2.38.
Figure 2.38
2. The constant velocity (Rzeppa type) joints in
the axle shafts that drive the wheels are lubri-
cated on assembly, and should need no further
lubrication in their normal service life.
See Figure 2.39.

NOTE: Grease is contained in the constant
velocity joint boots. If a boot is damaged, the
grease will get contaminated. Once the grease
is contaminated, accelerated wear and joint fail-
ure will occur. Replace any damaged boot as
soon as possible. Clean and inspect the boots
regularly.

3. The transfer case contains 64 fl.oz. (1.9 l.) of
80W-90 Low Foam Oil (Cub Cadet P/N: 737-
04040). See Figure 2.40.
• The transfer case oil should be changed after
the first 5 hrs. of use, 50 hrs. of use, and at 500
hr. intervals thereafter.
• Inspect the transfer case vent at 100 hr. inter-
vals. A blocked vent will cause fluid loss.
• The transfer case gear lube should be checked
at 100 hr. intervals, or more frequently if fluid
loss is noticed.
• In the event of fluid loss, identify and repair the
leak as soon as possible to prevent catastrophic
failure of the transfer case, disabling the vehicle.
4. To check the fluid in the transfer case:
