L322 Range Rover Service Procedures
GENERAL INFORMATION
03-8
l
When fitting a bearing to a shaft, only apply
force to the inner ring of the bearing. When
fitting a bearing into a housing, only apply force
to the outer ring of the bearing.
l
In the case of grease lubricated bearings (e.g.
hub bearings) fill the space between bearing
and outer seal with the recommended grade of
grease before fitting seal.
l
Always mark components of separable bearings
(e.g. taper roller bearings) when dismantling, to
ensure correct reassembly. Never fit new rollers
in a used outer ring; always fit a complete new
bearing assembly.
Oil Seals
General
Always renew oil seals which have been removed
from their working location (whether as an individual
component or as part of an assembly). NEVER use
a seal which has been improperly stored or handled,
such as hung on a hook or nail.
l
Carefully examine seal before fitting to ensure
that it is clean and undamaged.
l
Ensure the surface on which the new seal is to
run is free of burrs or scratches. Renew the
component if the original sealing surface cannot
be completely restored.
l
Protect the seal from any surface which it has to
pass when being fitted. Use a protective sleeve
or tape to cover the relevant surface.
l
Lubricate the sealing lips with a recommended
lubricant before use to prevent damage during
initial use. On dual lipped seals, smear the area
between the lips with grease.
l
If a seal spring is provided, ensure that it is fitted
correctly. Place lip of seal towards fluid to be
sealed and slide into position on shaft. Use
fitting sleeve where possible to protect sealing
lip from damage by sharp corners, threads or
splines. If a fitting sleeve is not available, use
plastic tube or tape to prevent damage to the
sealing lip.
l
Grease outside diameter of seal, place square
to housing recess and press into position using
great care, and if possible a 'bell piece' to
ensure that seal is not tilted. In some cases it
may be preferable to fit seal to housing before
fitting to shaft. Never let weight of unsupported
shaft rest in seal.
