Bearing lubrication

Refer to Figure 6-6. Proper lubrication of the portable
compressor's bearing axle is critical to its proper function
and reduction of wear on this part. Wheel bearings
should be lubricated at least every 12 months, or more,
to ensure proper performance and minimize wear. Use a
wheel bearing grease that conforms to MILSPEC MIL-G-
10924 or a high temperature one such as lithium complex
NLGI consistency #2.
Axles with the E-Z Lube feature can be periodically lubri-
cated without removing the hubs from the axle. This fea-
ture consists of axle spindles that have been 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 then back out of the
grease cap hold (see Figure 6-6).
1. Remove the rubber cap from the grease
cap's end.
2. Using a full charged grease gun, place the
gun onto the grease zerk located on the end
of the spindle. Make sure the nozzle is fully
engaged on the fitting.
3. Pump grease into the zerk. The old grease
will be displaced and flow out of the cap
around the grease gun nozzle.
4. When the new grease starts flowing out of the
cap, disengage the gun and wipe off any excess
off the cap; and replace the rubber plug.
