SWING ARM BUSH BSA B44/TRI 25 - Replaces 40-4241
Swing arm pivot bush for BSA B44 and Triumph 25 models, part number 82-8993, replaces 40-4241.
This is a swing arm bush listed for the BSA B44 and Triumph 25 models, carried under part number 82-8993. The catalog record shows it replaces the older 40-4241 number, so if your parts book still lists 40-4241 you're looking at the same physical piece under its current number.

The catalog also cross-references this to 97-0388 and the legacy H388 prefix form, which is worth knowing if you're trying to match up a bush from an older book listing. A swing arm bush of this type sits in the swinging arm pivot, taking up the play between the arm and the frame pivot tube and letting the rear suspension move without slop.
Our record on this one is brief beyond the cross-references, so if you're not certain your machine matches the B44/Triumph 25 listing, give us a call and we'll confirm before you order.
