O-RING,OIL PUMP-3CYL
O-ring that seals the oil pump on Triumph triple-cylinder engines, PN 70-6570.
This is the oil pump O-ring for the triple-cylinder Triumph engines, part number 70-6570, also known under the older C015 designation. It seals the oil pump body against the crankcase to keep oil pressure where it belongs instead of seeping past the pump housing.

It's a small part but an important one for keeping the lubrication circuit tight. If you're pulling the oil pump for inspection or cleaning on a triple, this is worth replacing rather than reusing the old one, since a tired O-ring is a common source of a slow oil leak or lost pressure at that joint.
We don't have much more detail on file for this one beyond what's in the catalog record, so if you're not sure it matches what's on your pump, give us a call and we'll confirm before you order.
