PRIMARY GASKET 1954-59 TRIUMPH GENERATOR CASE
Primary chaincase gasket for 1954-59 pre-unit Triumph twins with generator (dynamo) charging.
This is the primary chaincase gasket for pre-unit Triumph twins running the generator (dynamo) style charging system, catalog dated 1954-59. It seats between the primary case and the engine, sealing the chaincase that houses the primary chain and clutch so oil stays where it belongs instead of weeping out at the joint.

You'll also see this part turn up under the older T1189 number, which is the legacy form of the same gasket before Triumph moved to the modern 57-series numbering. If you're working from an old parts book that lists T1189, that's this gasket.
We don't have much more on file for this one beyond the basic description, so if your bike's charging setup or case style is in question, give the shop a call and we'll help confirm before you order.
