Who amongst us possesses or has experience with these older CT90-type bikes?  I am gradually sorting through my 1965s dual sprocket rear axle, but I cannot figure out how to put it all together so that the axle bolts are tight enough to stay on without binding the rotation of the rear wheel.  There may be some later-model bits that came with the bike, but do not seem to fit properly.

A look-see of a similar, correct bike would be really helpful.

I have two of these in bits but cannot advise on assembly as I have not done it yet. Could possibly come up with some spare bits but have not dredged through theses boxes in many years.

Thanks, Frank.   This bike is pretty complete, just needed just about every bolt touched.  Reassembly shows where questionable repairs have been attempted.  Actually, I had it running up the street late summer, so not a lost cause, by any means.

Canucklehead Graeme restored one last year.

if there are spacers on the axel make sure they only go up against the bearing inner race. sometimes one end is bigger than the other. good luck.

Thanks, Ken.  On mine, the spacer is symmetrical, same size on both ends.  I've checked with another source of knowledge, and it appears that I am correct in my required parts and assembly order.  I will try a nyloc nut on the chain end of the axle, and not tighten the main nut and axle nut down so much.

It seems that the axle nut is just there to keep the axle from slipping out the other end, with the main nut holding the tightness of the chain.

I never had any trouble with that axle. Had both wheels off to replace the tires. As with every bike I've had, I snugged it up so it wouldn't move. The wheel spun just fine.

Newer/"different" hub.  You may have a project to massage some metal.

Probably have to bring the frame to get the right fit.
