Trying to replace the gearbox seal on my 59 B33 BSA. Having trouble removing the spindle at the end of the drive shaft coming out of the gear box into the clutch. Held in with a key I believe and could be threaded, I just don’t know. Can’t get a puller on the nubby spindle. Any body know how this comes off?

I assume you are talking about the clutch center hub. The trans main shaft is tapered and the hub engages the taper and is further kept from turning by the key. There are pullers that screw onto the hub to facilitate removal. Do you have a 4 spring or a 6 spring clutch ? 4 spring puller is a Triumph tool, 6 spring puller is a BSA item. Make sure the tool fully engages the threads before you apply pulling pressure or you might damage the puller or hub threads. Sometimes helps to tap on the puller after you apply pressure. Sometimes helps to heat the hub. Sometimes you have to put pressure on the hub with the puller and just wait (maybe days). It can be a real drama to get the clutch hub off. Hope yours comes easy.
