173 has killed 2x N/S rear bearings in 3 months!

Evening guys. Long time, no see.

The bullet is still in my possesion (just) and has failed its MOT on a few niggly points today, 1 being the N/S rear bearing.

I first changed the rear bearing about 3 months ago after it gave way spectacularly around a roundabout and ended with the rear wheel having 2 inches of lateral movement.

The old bearing literally fell off. At the end of the stub axle was a washer with a tapered lip which I assumed should be there but I couldn't remember how it should sit at rebuild time.

I fitted the washer flush to the back of the stub axle with the taper pointing towards the wheel sitting inside the new bearing. This bearing died abut 4 weeks later.

I rebuilt it again but the new bearing has now gone.

Can someone confirm the correct configuration and also the correct torque setting.

Thanking you.

sorry cant help you but havent seen you around for a bit,you keeping ok?
I've been good thanks mate. Had a stressful 6 months though.

I've put my heart and soul into my job, moved house and my partner has not been too well. All is good now though. Settling in nicely, the graft has resulted in a very tidy promotion and Doris is all clear too.

Just the tin pot to cause me stress now LOL!
