Always replace 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 every seal before fitting to make sure that it is clean and undamaged.

• Make sure the surface on which the new seal is to run is free of burrs or scratches. Replace 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.
