III automatic transmission
fluid. See the manufacturer's operator manual for intervals and
quantity.
앫
Manual transmission: Use a mineral or synthetic oil. Check oil level
periodically. Level should be to the bottom of the inspection hole.
19. Auxiliary axle(s):
If equipped, use a lithium-based grease with
specification API NLGI No. 2. Also, lubricate the brake, cams, slack
adjuster and tie-rod ends.
20. Rear axle:
Check the oil level in the differential by removing the fill/level
plug in the housing. The oil should be level with the bottom of the fill/
level plug hole. Add oil if necessary.
Most rear differentials have a large screw and nut protruding from the
housing. The screw and nut hold the thrust plate shoe against the ring gear
and are not to be confused with the fill/level plug.
21. Fifth wheel:
The fifth wheel and slider assemblies should always be
re-lubricated after steam cleaning or at least every 24 000 km
(15,000 miles).
A heavy coating of grease is recommended on the fifth wheel plate by using
the grease fitting under the fifth wheel top plate or by direct application to the
top of the plate. The fifth wheel can be greased with the trailer connected, by
using the grease fittings under the top plate.
Grease the support brackets trunnions through the fittings over the bracket
pins.
Grease the fittings at the saddle plate (1 each side) and the saddle plate lock
pockets (1 each side).
See “Oil Capacity Tables and Viscosity Charts” on page 108 for oil types.
