A timing cover oil seal guide tool (alias D486) used to protect the crank oil seal when refitting the timing cover.
60-0486 is a timing cover oil seal guide tool, sometimes called by its earlier alias D486. It's a service tool rather than a part that stays on the bike: you use it to protect the crankshaft oil seal in the timing cover while you're fitting the cover back into place, so the seal lip doesn't get cut or rolled by the crank threads.

The catalog places this tool in Triumph service listings spanning 1964 to 1969 in our records, and it shows up across a number of gearbox and toolkit-related figure entries. Because it's a guide tool tied to a specific timing cover thread, it's worth confirming you've got the right one for the cover you're working on before you buy - there's a related tool for later covers that isn't this same part.
If your parts book lists this under D486, that's the same tool under its older factory number.
