GENERAL INSTRUCTIONS
LUBRICANT REQUIRED FOR SYSTEM
Grease requirements will depend on ambient tem-
peratures encountered during truck operation:
Above 32°C (90°F) - Use NLGI No. 2 multi-
•
purpose grease (MPG).
-32° to 32°C (-25° to 90°F) - Use NLGI No. 1
•
multipurpose grease (MPG).
Below -32°C (-25°F) - Refer to local supplier
•
for extreme cold weather lubricant require-
ments.
System Priming
The system must be full of grease and free of air
pockets to function properly. After maintenance, if
the primary or secondary lubrication lines were
replaced, it will be necessary to prime the system to
eject all entrapped air.
1. Fill lube reservoir with lubricant, if necessary.
2. To purge air from the main supply line, remove
the main supply line at the grease canister.
Connect an external grease supply to the line.
3. Remove plugs from each injector group in
sequence (right front, left front, and rear axle).
4. Using the external grease source, pump grease
until grease appears at the group of injectors
and re-install the pipe plug. Repeat for remain-
ing injector groups.
5. Remove the caps from each injector and con-
nect an external grease supply to the zerk on
the injector and pump until grease appears at
the far end of the individual grease hose or the
joint being greased.
Filter Assembly
The filter assembly element (5, Figure 3-4) must be
replaced if the bypass indicator (2) shows excessive
element restriction.
