BUSH SMALL END BSA B44/50
Bronze small end bush for BSA single-cylinder engines (B44/B50), fits into the connecting rod eye where the wrist pin rides.
This is a small end bush for BSA single-cylinder engines, not a Triumph part despite how it shows up filed in our records. The description on the catalog card is plain: bush, small end, BSA B44/B50. It's a bronze bushing that sits in the eye of the connecting rod at the small end, where the piston's wrist pin (gudgeon pin) rides.

We carry it under 66-0492, which also turns up in older listings as V147 — same physical part, different number depending on which book you're holding. If you're pulling a BSA single motor down for a rebuild and the small end is worn or knocking, this is the bush you're after.
We don't have more detail on this one beyond what's on the card, so if you're not sure it matches your rod, give us a call and we'll sort out fitment before you order.
