How to Remove a Scotseal
000103
NOTE
The Scotseal maintains a metal-to-metal contact between the seal outside diameter and the hub
bore surface, as well as a metal contact between the packing I.D. and the spindle.
1.
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.
2.
Do not clean the seal. In this case, dirt can be helpful in providing valuable clues.

1.
Thoroughly clean wheel hub and seal bore.
2.
Thoroughly clean spindle and spindle threads.
3.
Pre-lubricate the inner bearing with GAA.
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.
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.
