(purple) to shoulder on spindle or axle tube, and
place wiper ring on axle tube or spindle using an
installing tool (Figure 20). Remove excess
Gasket Eliminator sealant.
Figure 20. - Installing Wiper Ring on Axle Shoulder
The care with which the axle ring is Installed
cannot be over-emphasized. Damage to this
ring will result in shortened seal life.
2.
Tap on end of axle tool driving axle ring firmly on
shoulder until axle tool contacts shoulder.
3.
Check position of axle ring to make sure edge of
ring is parallel with shoulder.
Lip Type Seal (Grease Packed Bearings)
Lip Type Seal With Wiper Ring (Oil Lubricated
Bearings) - Not Guardian Oil Seals
The following instructions pertain to lip type wheel seal
used with grease lubricated bearings as well as lip type
seals with wiper ring used with oil lubricated bearings.
1.
Apply a thin coat of Loctite Gasket Eliminator
(purple) hub seal bore. The coating must be
very light, yet cover press fit area. Gasket
Eliminator should never be allowed to contact lip
of seal nor contaminate oil.
2.
Lay wheel flat on a steady surface with brake
drum up. Place inner wheel bearing into bearing
cup and place hub seal Into starting position on
hub.
3.
Install hub seal using SE-1905 Installer Set to
prevent cocking seal (Figure 21). Select the size
disc which will apply force to outer edge of hub
seal and prevent seal from becoming distorted
or damaged.
Figure 21.
Drive hub seal into hub until it bottoms in hub bore. Do
not continue to drive after seal is once seated as this will
distort or damage the seal. After removal of seal installer
tool, clean off excess Gasket Eliminator. Be sure to
confirm uniform seating of seal (Figure 22).
Figure 22.
Unitized Scot Seal
1.
If seal is being changed to a unitized seal from
another type, remove wear rings if present. Do
not use a chisel to remove wiper ring since the
chisel could mar the axle. Use a ball peen
hammer and tap the ring lightly on the seal lip
surface. Do this in a small area, causing the ring
to expand, and allowing the ring to slip off the
axle housing.
