It is important to note that most mounted tires will deect fairly easily when
enough hand pressure is applied while shaking the tire. Excessive pressure
will result in the perception that the bearings’ tilt is greater than it actually is.
This same phenomenon will occur when checking any wheel end, even those
equipped with conventional bearing sets.
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 tted 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.
