XLC Bearing Installation
2.1 The XLC bearing will come from the factory partially assembled without
the wiper seals and O-rings installed. Partially disassemble the bearing for
installation.
2.1.1 Unbolt the halves of the
housing and set aside the
cap screws for future use in
assembly.
2.1.2 Unbolt the halves of the
carrier assembly and set
aside the cap screws for
future use in assembly.
2.2 Join one ball and socket O-ring
around the shaft.
2.2.1 Do not attempt to disconnect
the O-ring. This will destroy
the locking feature and make
the O-ring unusable.
2.3 Place upper wiper jacket around
shaft so the anti-rotation tab points
up. Insert ball and socket O-ring into
wiper jacket cavity from below.
2.3.1 Repeat step 2. 2. Place
lower wiper jacket around
shaft so the anti-rotation tab
points down. Insert ball and
socket O-ring into wiper
jacket cavity from above.
