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.
• Carefully examine seal before fitting to ensure that it is
clean and undamaged.
• 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.
• 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.
• 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.
• 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.
• 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.

General Information
• Use the recommended service tool to fit an oil seal. If
the correct service tool is not available, use a suitable
tube approximately 0.4 mm (0.015 in.) smaller than
the outside diameter of the seal. Use a hammer VERY
GENTLY on drift if a suitable press is not available.
