MAINTENANCE (CONTINUED)
E-Z LUBE® LUBRICATION
The Procedure is as follows:
1. Remove the rubber plug from the end of the grease cap.
2. Place a standard grease gun into the grease fitting located in the end of the spindle. Make sure
the grease gun nozzle is fully engaged on the fitting.
3. Pump grease into the fitting. The old displaced grease will begin to flow back out the cap around
the grease gun nozzle.
4. When the new clean grease is observed, remove the grease gun, wipe off any excess, and
replace the rubber lug in the cap.
5. Rotate hub or drum while adding grease.
NOTE:
The E-Z Lube® feature is designed to allow immersion in water. Axles not equipped with E-Z Lube®
are not designed for immersion and bearings should be repacked after each immersion. If hubs are removed
from an axle with the E-Z Lube® feature, it is imperative that the seals be replaced BEFORE bearing
lubrication. Otherwise, the chance of grease getting on brake linings is greatly increased.
BEARING REPLACEMENT AND DRUM INSTALLATION
1. Once the drum and bearing assembly is removed from the axle, remove “internal snap ring from
the bearing bore that retains bearing.
2. Using an arbor press and mandrel, press the bearing out of the
drum. Bearing will exit on the wheel side of the drum
3. When replacing a Nev-R-Lube™ bearing pack, the bore in the hub
should be cleaned and inspected for visual damage (replace as
necessary).
4. Install the new bearing using an arbor press fitted with a hollow or
stepped punch face to press only on the outer housing of the
bearing. Failure to follow procedure will damage the bearing and /
or seals during installation. Press bearing until it seats against the
backup shoulder machined into the hub.
5. Install “internal” snap ring into hub.
6. Clean and inspect spindle shaft. Apply a light coating of anti-seize lubricant to the spindle shaft
prior to assembling drum.
