Frequently Asked Questions

Q: What information should be supplied to find the correct seal?

A: The following options are give in order of preference

  1. The make model and year of the vehicle.
  2. Numbers from the old seal.
  3. The outside diameter, shaft size and width of the seal and the constuction of the seal.


Q: Should a modern seal be used where the original was metal/leather?

A: A modern seal can be used but only if the shaft to which it is sealing has a suitable surface finish. If for example the shaft is a new axle shaft this will probably be OK. If the shaft has any imperfections a leather seal will usually seal better as the lip of a leather seal is wider than a modern neoprene seal. If the shaft is made of a soft material a modern seal can wear a groove in the surface for the same reason.


Q: How should leather seals be prepared for fitment?

A: The following steps are recommended for best results

  1. If there is any corrosion or light rust on the metal casing of the seal this should be removed with fine emery cloth or wire wool.
  2. If the leather is coated in a protective coating of grease this should be removed with white spirit.
  3. Soak the seal for at least 24 hours in oil in a warm place.
  4. Drain excess oil from the seal before fitment.
