SEAL, POINTS/ TIMING SIDE CRANK OIL FEED - HIGH PRESSURE RATED PIONEER BRAND - TRIUMPH TWINS AND SINGLES
Timing-side crank oil feed seal, Pioneer brand, high-pressure rated, for Triumph twins and singles.
This is a crank oil feed seal for the timing side of Triumph twins and singles, sitting where the crankshaft passes through the timing cover on the points side. It's the seal that keeps oil pressure contained at that feed point instead of leaking out around the crank. This one is the Pioneer brand version, rated for higher pressure than a standard seal.

The part number 70-4568P replaces the older factory numbers 70-4568 and 76-0291, so if your parts book or an old box in the shed has one of those numbers on it, this is the current equivalent.
We don't have much more detail on file for this one beyond what's in the description. Since it's an oil seal in a spot that sees pressure, it's worth checking your timing cover and crank bore condition before fitting a new one, and give us a call if you want to confirm it's right for what you're working on.
