I am fitting a rear wheel to my D1 plunger build, the wheel I am fitting did not have a sprocket so I fitted a new one, new rim tape tube and tyre, bearings ok..... all ready to fit, but, the spindle I have is not the correct diameter, it's too small.

Reading other posts it seems there are two sizes, and two sizes of bearings, it looks like I need a new 'larger diameter' spindle, my question is, are all the wheel nuts, locking nuts etc the same size on both spindles and it is just the central unthreaded section of the spindle which is a larger diameter?

also, does anyone know who stocks them?

Thanks Larry

The spindle is larger in diameter along it's whole length so new fittings will be needed.  I don't think you can buy new spindles but they do come up for sale on eBay either as individual items or in hubs.

thanks, I will look out for one or complete new wheel, these mistakes are made to test us, I should have checked that the spindle fitted first!

I have it down as 9/16" BSF, BSA part No. 90-6092

Supposed to come with a nut, as a set.

See also, for other parts:

From around February onward I managed to get hold of stainless versions of most of the nuts etc., eBay etc.

Thanks, I have bought a second hand wheel with spindle and most fittings, so I am sorted now, so it is tyre off the old one and refurb the new one.

another lesson learned when buying 2nd hand wheels!

thanks All, larry.

Hi Larry, do you still have the small spindle?  If so, would you be willing to sell it? I'm trying to find parts to build a rear wheel for a rigid.

It sounds like you have a rear wheel for a rigid machine. Pictures/measurements would help. You cannot just “swap the spindles” the whole assembly is different. 

There are people on the forum in the opposite position to you, who have a plunger wheel and a rigid frame. It may make more sense to look to do an exchange of wheels with someone than to modify what you have; even if it means removing the tyre and sprocket again. 

While it would be possible to make up some new shouldered nuts to allow you to fit the wheel to your plunger frame, BSA increased the size of the spindles for a reason; that being the fact that the smaller one is not strong enough to withstand the additional forces put on it by the rear suspension movement, so I could not in any conscience advise that route.

Yes I modified the plunger type wheel nuts to use a plunger wheel in my rigid, the plunger spindle fits the drop outs,

Turned off just enough of the sleeve so as to retain the adjusters but to enable the nuts to clamp the frame.

Not got to sorting out the brake rod yet. 1605968305721824358488.jpg1605968389218434178828.jpg
