HEEL EARING UBRICATION
Refer to Figure 6-2. Proper lubrication is essential to
the proper functioning and reliability of your portable
compressor axle. Wheel
lubricated at least once every 12 months, or more
frequently to help insure proper performance. Use
wheel bearing grease that conforms to military
specification MIL-G-10924 or a high temperature
wheel bearing grease such as lithium complex NLGI
Consistency #2.
If your axle is equipped with the E-Z Lube feature,
the bearings can be periodically lubricated without
removing the hubs from the axle. This feature
consists of axle spindles that have been specially
drilled and fitted with a grease zerk in their ends.
When grease is pumped into the zerk, it is channeled
to the inner bearing and then flows back to the outer
bearing and eventually back out of the grease cap
hole (refer to Figure 6-2). The procedure is as
follows:
1. Remove the rubber plug from the end of the
grease cap.
2. With a standard grease gun filled with a qual-
ity wheel bearing grease, place the gun onto
the grease zerk located in the end of the
spindle. Make sure the grease gun nozzle is
fully engaged on the fitting.

3. Pump grease into the zerk. The old, dis-
placed grease will flow back out of the cap
around the grease gun nozzle.
4. When new, clean grease is observed,
remove the grease gun, wipe off any excess,
and replace the rubber plug in the cap.

Refer to Figure 6-3. The main fluid filters are located
schematically in the coolant line between the
receiver tank and the compressor unit. The main filter
elements are replaceable. For installation of the filter
elements, follow the procedure explained below:
1. The compressor MUST be shut off and sys-
tem pressure MUST be relieved.
2. Position a suitable container beneath the
elements to catch fluid drainage.
3. Remove elements using a suitable tool.
4. Rotate each element counterclockwise to
remove.
5. Remove element and discard. These ele-
ments are not cleanable.
6. Make certain that the mounting surfaces and
filter heads are clean.
