MAINTENANCE, LUBRICATION AND SERVICE
LUBRICATION
Manual Transmission
Use a mineral or synthetic oil. Check
oil level periodically. Level should be
to the bottom of the inspection hole.
20 Auxiliary Axle(s)
If equipped with auxiliary steer, lift or
steerable lift axles use a lithium
based grease with specification API
NLGI No. 2.
Also, lubricate the Brake, Cams,
Slack adjuster and Tie-rod ends.
21 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. The check
should be performed parked on a flat
level surface.
CAUTION
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.
NOTE
Refer to Service information for Oil Types
and for Approved/Correct Oils.
22 Fifth wheel
The fifth wheel and slider assemblies
should always be re-lubricated after
steam cleaning or at least every oil
change.
Due to different manufactures of 5th
wheels and models, some 5th
wheels may not have grease fittings.
Use a lithium based grease with
specification API NLGI No. 2 on
tracks and moving components.
NOTE
A heavy coating of grease is
recommended on the fifth wheel plate by
using the grease gun or a putty knife by
direct application to the top of the plate.
