Swinging arm spindle, engine and gearbox mounting bolts

Posted by Dan Field at Wednesday 22:36

Im trying to build a bike from bits but I don’t have any mounting bolts (except gearbox upper mounting) does anyone have a list of the bolt sizes and threads so I can procure them?

Cheers

Oops .... Sorry should have said, in my defence it was past my bet time! It’s a 1955 pre featherbed swinging arm frame fitted with amc gearbox. Thanks for the molnar link, they seem to have some, but not the swinging arm spindle. sadly I don’t have a parts book yet which doesn’t help!

I notice that the LHS swinging arm mounting in the frame is in fact a slot, having found that I do have a parts book I can’t see any special washer or bush, how do you make sure that the arm is central in the frame.
