Norton Chaincase/Oilbath Rubber Seal - Normal Type (All Models)

This item is the rubber seal that fits around the circumference of the Norton inner chaincase/Oilbath, and provides an oil seal to the Norton type pressed steel oil bath.

Fits all roadgoing models using the Norton Oilbath

This particular type is the standard width type fitted to most SOHC and Postward models (and all road going models from the early 1930's through to the late 1950's). The width of the rubber seal is 7/8" (20mm).

We also sell a slightly slimmer version that was supposedly fitted to some WD16H models (Item 0359).  I have tried and these will also fit standard oil baths (if we are out of stock of these) - and may also fit the earlier late 20's/early 1930s Royal Enfield type chaincases (email for more information if you have one of those and need dimensions)
