VALVE SPRING SET- A7/10 47-62
Valve spring set for the BSA A7/A10, covering 1947-62 production.
This is a valve spring set for the BSA A7 and A10, covering machines built in the 1947 to 1962 span according to the catalog listing. It's a BSA part, not a Triumph part, so if you're working on a Triumph twin this one isn't for your bike.

Valve springs do the job of closing the valve after the cam and rocker have pushed it open, and a set like this covers what's needed for the job on this engine. Beyond that we don't have more detail on this one in our records.
The part also shows up under the numbers 60-0402B and D402B if that's what's printed in your parts book. Give us a call if you want to confirm this is right for your particular A7 or A10 before you order.
