PULLER,BSA MAGNETO PINION - 5/8-20
A magneto pinion puller tool, 5/8-20 thread, for removing the pinion from a Lucas magneto, also known as P108.
This is the magneto pinion puller, catalog number 61-1903, also known by the older P108 designation. It's a service tool, not a bike part — the kind of thing that lives in the toolbox rather than on the machine. Its job is pulling the pinion off a Lucas magneto so you can get in there for service or replacement without beating on the shaft with a drift and hammer.

The canonical description ties it to BSA magneto work, and the thread callout on the tool itself is 5/8-20. If you're working on a magneto-equipped machine and need to get the drive pinion off cleanly, this is the tool that's meant for the job.
We don't have much more history on this one in our records beyond the part number and its older P108 alias, but the tool itself is straightforward — one puller, sold each. Give us a call if you want to confirm it matches what's on your magneto before you order.
