WHEELS, RIMS AND TIRES
2.
Apply a thin coat of Loctite Gasket Eliminator
(purple) hub seal bore. The coating must be
very light, yet cover the press fit area.
3.
To install unitized seal in wheel, seat outer face
of seal in the recess of tool adapter (Figure 23).
Insert centering plug of tool in bore of inner
bearing cone (Figure 24). Using the centering
plug aids in prevention of seal cocking in-wheel
bore.
Figure 23.
Figure 24.
4.
Hold tool handle firmly and strike until sound of
impact changes when seal is seated (Figure 25).
Then inspect seal to be sure it is uniformly
seated but not crushed. Remove excess
sealant.
Figure 25.
IMPORTANT Any time wheel Is removed with
a Scot Unitized Seal for any purpose, the seal
must be replaced.
A good check of proper seal installation is to
move the synthetic sealing member with your
fingers after installation in wheel hub. There
should be a slight in and out movement possible.
If wheel seal parts requirements require a wiper
ring installation, refer to installation of wiper ring
in preceding text.
Unitized Barrier Seal
The barrier type seal (Figure 18) is installed by hand and
new seals do not require any special lubricant or sealer
to outer or inner surfaces, except when new seal
appears to be free of lubricant. Then it is permissible to
wipe the leading edge of inside and outside diameters
sparingly with light bearing oil. These seals do not
require any special tools for installation.
Position seal over hub and use care so that the seal is
not cocked when pushed into place.
Push seal into the hub by hand until it is completely
bottomed and uniformly seated in the bore.
Do not use wheel bearing or chassis grease to install
seals, since grease could result in seal slipping in hub or
on spindle or axle tube.
