Joint washer
A joint washer that seals the oil pump assembly on the engine's bottom end.
This is a joint washer for the oil pump assembly, sitting in with the oil pump and release valve components on the engine's bottom end. It's a small sealing piece that keeps oil where it belongs as it moves through the pump and manifold area rather than leaking out at the joint faces.

The catalog carries this under 71-1461, with 13-37705 and E11461 as the same part under older number forms. If your parts book is from the early-to-mid 70s and lists 71-1461, that's this washer. Triumph later renumbered it to 70-3730, so if you're working from a newer parts book or ordering against a current listing, that's the number you'll find it under now.
It shows up across a couple of oil pump figures in our records, tied to the release valve and manifold hardware. Given how cheap it is to keep one on hand, it's worth grabbing a spare any time you've got the oil pump apart, since these thin sealing washers rarely survive a second use once torqued down and disturbed.
