I'm trying to find the part number for the gear on the end of the 1355 process unit mag roller. The service manual shows the inner gear but there's also another gear at the end of the shaft that meshes with the dev drive gears. I've looked for it in the drive section page also but what they're calling the dev drive gear doesn't resemble the gear on the mag shaft.
Thanks!

Try 63814080 gear 18 magnet roller

Yep, that's the only one I see too. But that's the gear that is up close to the mag roller on the outside of the dev unit frame. The gear teeth on that gear face the mag roller. There is also a gear about 1/2 inch away toward the end of the same shaft that has a set pin and the gear. The teeth on that gear face away from the mag roller. Can't find that one. Might be #24 in the drive figure, #65822020 gear 15 dev drive gear since I'm looking for a 15 tooth gear. Picture just doesn't really match up with actual gear though but worth a chance I suppose.
