BSA Pinion, layshaft second gear (22 teeth)
Layshaft second gear pinion (22 teeth) from the gearbox cluster, catalog PN 41-3070.
This is the layshaft second gear pinion out of the gearbox cluster, 22 teeth. It's one of the gears that rides on the layshaft inside the gearbox and takes the drive from mainshaft to layshaft when you're in second, meshing with its mating gear to give you that ratio.

Our catalog record ties this part to the gear cluster figure with appearances spanning 1969 to 1970. That's what we can confirm from the books - beyond that we can't say which specific model or engine this cluster belongs to, so before you order, check it against what's actually in your gearbox.
If you're rebuilding a cluster, it's worth pulling the whole set and inspecting for wear on the dogs and teeth together rather than replacing this one gear in isolation, since mismatched wear between mating gears can cause problems.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
