70-4568 - Points Seal (Taiwan)

This particular Taiwan seal is rated very low and should only be used for the points seal on a vintage Triumph twin. We do not recommend using the Taiwan seal as the crankshaft seal despite it having the same part number  - it could cause low oil pressure.

70-4568 - Crankshaft Seal (USA)

The USA made seals we stock are the best quality seals to be used as a crankshaft feed seal and also as a points seal. Seals (just like original) are rated up to 100+ pounds to withstand oil pressure.

70-6387 - Crankshaft Seal (-.020")

If your oil feed spigot on your crank end shows signs of wear (grooving) it is wise to use an undersized seal. The 70-6387 seal features a smaller inner diameter (-.020) to make up the wear on your crankshaft end spigot. To be clear this part is the same as 70-4568 but with a smaller inner diameter.
