H-30. CR SCOTSEAL (Cont.)
How To Remove a Scotseal:
The first step is removing the
Scotseal from the hub. You do
this by inserting a pry bar
(crow's foot) between the seal
and the bearing cone. The bar
should rest on the inner race
to
avoid
damaging
the
bearing.
Do not clean the seal. In this
case, dirt can be helpful in
providing valuable clues.
NOTE
The Scotseal maintains a
metal
to
metal
contact
between the seal O.D. and th e
hub bore surface as well as a
metal contact between the
packing I.D. and the spindle.
Installation:
1.
Thoroughly clean the wheel hub and seal bore.
2.
Thoroughly clean the spindle and spindle threads.
3.
Pre-lube the inner bearing with GAA lubricant.
4.
Place seal onto hub bore and insert drive tool into the seal. Hold tool handle firmly and straight.
Drive seal into hub bore with firm hammer strokes.
CAUTION
Seal must be squarely seated when bottomed in hub bore. Check
for freedom of movement by manually moving the seal packing up
and down. A free movement of the packing is required for proper
bearing end play adjustment.
