O-RING - FILLER CAP 1 1/16 ID
O-ring seal for the filler cap, 1 1/16 in. ID, part of the FRAME group.
This is the O-ring that seals the filler cap, listed in the catalog under FRAME with an inside diameter of 1 1/16 in. It's a small rubber part but it does real work keeping oil from seeping out around the cap threads or lid, so a hardened or flattened one is worth catching before it starts weeping.

The older part number for this seal is D3616, which is the form you'll see printed in earlier parts books before the 60-3616 numbering came in. Triumph later renumbered this O-ring again to 70-7310, so if you're cross-checking a newer parts book and don't see 60-3616 listed, that's where it went.
Catalog appearances for this seal run from 1971 into 1985, so it shows up across a fair stretch of production. Cheap to keep a spare of on the shelf since these do dry out and crack with age.
