Sleeve gear

Forums

When did Norton stop using rollers in the sleeve (4th) gear (behind the thrust washer), and why?. Ive just ordered some rollers for a laydown gearbox. It was stripped so I assumed it had rollers in, same as an upright box. Looking at the parts list for the laydown, the rollers are omitted.

Cheers

John.

P.S. thanks for the help so far, great forum with informative chaps (and chapesses)

Hello From Chapess, Well I maybe wrong here but I think it was when they went to the AMC Box in September 1955. Yours Anna J Dixon

The laydown definatly does have rollers in the sleeve gear as standard, but I know someone who has machined the sleeve gear on his dolls head box to take a bush same as the AMC box
