Hello!

Yesterday I picked up my bsa's wheels. I had them in a workshop for new brakes, tubes and tyres. I chose a heidenau tyre with a modern-classic design, but which is safer to ride than the old made-in-india dunlop.

But yesterday I wasn't able to fit the rear wheel correctly. If I try to tighten all the nuts, the weel won't turn (which has been kind of a joke between my coworkers: "after all the money spent, you own a bike with non-turning wheels"). If I loosen the nuts, the wheel can turn, but it doesn't stay in position, and the rear axle moves forward and backward.

Is there any method to tighten the nuts and the axle that I am missing? Could someone tell me which order or precedure to follow?

And another question: on the left side of the axle, there is a funny eccentric washer (66-6096). I don't think it was just an artistic design, but I have no idea of what it is, or how it works. Could anyone tell me?

Thanks,
Albert Pascual

Eccentric washer is a cam that moves your rear wheel spindle forward or backward to adjust your driving chain tightness

It's very easy to put the 'SNAIL CAM' upside down. Which will still work to adjust the chain but will have an adverse effect on the position of the rear stand in the up/riding position.

It's all in the workshop manual and worth getting one for all the routine maintenance procedures. Ron

Oh. I see.

My BSA lacks the alignment adjusting screw. I knew there had to be some problem. Straight to my wishlist!

Thanks!

I am afraid there may be more wrong than the missing screw which is horizontal as the diagram is rotated 90 deg.

Inside the hub should be a spacer adjusted by a nut with vernier pin, washer with corrosponding holes & a lock nut.
You will find the drawing in the technical section of this site.
Overtightening can put a small load on the wheel making it a little stiff to turn but if it locks up fully you have problems inside the hub which could cause the bearings to fail ( not funny )

And there is very little space so you need either the original BSA tool or a tube spannar to tighten / loosen them.
Sorry about the LH thread I should have mentioned it, having just installed new rear bearings myself.

There is also a hardened thrust washer that fits over the bearing carrier sleeve...If that's missing the wheel will lock up when the nuts are tightened.....

It's best to get the manual and parts list if you are unfamiliar with the bike...That way you'll have a chance of sorting it...

I believe Henk has them all on CD for a reasonable cost...Ian

Hi

Just need to check that the sequence of re-assembly for the half spindle is:

Half spindle nut with peg, followed by the half spindle nut lock washer, followed by the half spindle nut lock.

I can't seem to see clearly on the Maintenance Manual.

Thanks in advance of your help.

Regards

Pat
