British Bikes / Re: T140 rear wheel, binding when tighten spindle
« Last post by iansoady on November 07, 2024, 04:48:06 PM »
Some bikes have a top hat spacer that fits inside the speedo drive to stop it being crushed. But I don't know about T140s.

If you're sure the bearings are fully home, try adding a suitable washer under the centre of the speedo drive on the wheel spindle and then see if the wheel spins freely.
I've had a few do this over the years, and a spacer seems to free up the working of the speedo drive from being clamped by the wheel spindle.

British Bikes / T140 rear wheel, binding when tighten spindle
« Last post by Eedward on November 07, 2024, 01:52:36 PM »
Hi all.
I have had a couple of T140's over the years, and love them. I've now got another, which came mainly in 'kit form' and am slowly assembling the kit ! All is going well, though I am scratching my head with the rear wheel assembly. When I tighten the spindle, with everything apparently in place, it pinches the assembly and the wheel won't rotate freely. It appears there is something missing, though as I didn't dismantle it, it is hard to find what is missing. I believe it's something on the right side, something around the speedo drive unit, a washer/spacer maybe, just difficult to see what's missing in the manual pictures. Any thoughts/help would be much appreciated.
Thanks, Edward

I had to use the large horn so it could be heard over the exhaust.😁

Looks to be the same engine as my old Coventry Eagle had fitted.
I guess you'd need a pokey engine to drag that huge horn around... ;)

Yes shim stock, .1mm thick. Here's before and after pics, I didn't  want to repaint the tank because I'd lose that originality so have done little cosmetically on any of the bike.

Get a pic ?

We are assuming this stuff must be mighty thin - shimstock ?

Update in case someone else might find it useful.  I curled a 3/4" x 10" strip of 316 (a4) stainless into a 7" circle and wound it inside the carb. It's springiness held it tight to the outside and tried the fit, it was too tight so kept removing 1/2" of length until it was a snug fit. Carb is now tight with no air leaks and engine running sweet. Many thanks to all for your suggestions.

Yes, Villiers did eventually move to bronze manifolds. Seems to have started in the late thirties as I have 9D engines with brass manifolds. They last much better than aluminium but boy, are they heavy.

If I ever make any more they will be bronze.

I too worried about electrolytic action between brass and alloy so have ordered stainless shim (I never thought about a drinks can). This combination seems to work on marine equipment fairly well. I did notice in the kit of spares is a bronze manifold but this would seem to carry the carb at a odd angle but is worth digging out and checking again. Thanks all for your input, I now have a few avenues to try.
