LUBRICANT REQUIRED FOR SYSTEM

Grease requirements will depend on ambient tem-

peratures encountered during truck operation:

multipurpose grease (MPG).

• -25° to 90° F (-32° to 32° C) - Use NLGI No. 1

multipurpose grease (MPG).

• Below -25°F (-32° C) - Refer to local supplier for

extreme cold weather lubricant requirements.

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 (2, Figure 3-1) at the pump

outlet port and connect an external grease sup-

ply 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 (21, Figure 3-2) element should

be replaced if the bypass indicator shows excessive

element restriction. See Figure 3-5 for detailed infor-

mation about the filter assembly.
