Primary Chaincases for Triumph Pre-Unit Motorcycles
(Alternator/Swingarm Models)
An improved sealing arrangement around the gearbox mainshaft gives the new Triumph pre-unit alternator primary chaincases a big advantage over the originals. The system utilises a lipped seal running on the high gear bush. The case has a wider gasket face. The kit comes with the stator ring (machined to take a modern stator) and all gaskets, screws, etc. Highly polished finish; made in the UK.
