British Bikes / Re: T140 rear wheel, binding when tighten spindle

Thanks for that, very helpful.
What keeps the face away from the hub to stop it wearing, as it has done on mine ?

Hi again.

I had yet another head scratch while looking at it, as spacer (as mentioned by L.A.B.) is there, though there is nothing to stop the spedo drive from being pinched/bind against the wheel as there seems to be a spacer or something missing. In one of the photos, if you can see, there is a space between the wheel spacer and spedo drive and I wondered if there needed to be something there so they didn't touch when the spindle nut is tightened, and therefore binding on the wheel hub ? If so, I can't see anything in the manual to show this.

I have attached some photos to try and show what I mean.
Further thoughts would be much appreciated.

Thanks,
Edward

Thanks for the replies chaps, much appreciated.

L.A.B. I will have a look at the spacer you mentioned, that sounds like what is missing ! Thank you.

British Bikes / T140 rear wheel, binding when tighten spindle
« 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

British Bikes / 1979 T140 rear wheel spindle set up ?
« on: September 20, 2022, 04:23:37 PM »
Hi all.
I have been away for a while as sold my last T140, sadly, though have now recently bought one again.
It was in bits, pretty much everything was off it following the previous owners aborted rebuild, hence the pile of bits. As I didn't take it apart, it is harder to put it back together, though doing ok. The problem I have at present is the rear wheel spindle assembly. When I put it back together and tighten it up, the wheel pinches and does not spin freely. I've looked at images of how it should look with spacers/speedo drive etc, and it looks as it should. I've tried various combinations though it always pinches when tightened up.

Any advice/thoughts would be much appreciated.

Thanks a lot, Edward

British Bikes / T140 regulator/rectifier replacement
« on: July 14, 2019, 09:59:24 AM »
Morning chaps and chapesses.

Can I ask please, what are your thoughts about replacing the regulator/rectifier with something along the lines of a Wassell or similar solid state one ? Who has done this, were there any benefit over the original setup, eg starting/running etc, and how easy/hard are they to fit ?

My bike starts fairly well, only a few kicks needed, though I think would benefit from a card set up, as it doesn't always tick over when up to temp, unless the tick over is raised a little.

Thanks,
Edward

Thanks a lot for your thoughts. I will have another look / head scratch and take it from there.
Thanks again,

British Bikes / Re: T140 strange oil leak

Thanks L.A.B.

Sorry, yes, it's an S reg = 1998 T140V, a positive earth model.
There is no breather from the exhaust rocker cover anywhere, just the crank breather where it exits behind the barrels on the left.
It does chuff a little smoke on over run, which suggest worn valve guides or rings ? Though why would oil, not just fumes, be exiting from the breather behind the head stock ? Could it be pressurising the oil in the frame, A - because there is no exhaust rocker breather, and/or B - because the valve guides/bores are worn, and therefore sending it out the frame breather that way, along with some oil ????
Also, where does the exhaust rocker cover actually breath from, as my last 1981 T140V didn't have a breather there either ?

Your further thoughts would be much appreciated.

Thanks,
Edward

British Bikes / T140 strange oil leak
« on: July 12, 2019, 07:34:00 AM »
I have recently been lucky enough to be the proud owner of a 1979 T140. I owned one a few years ago though sold it, now my garage is happy again with another one in it's place !
All is fairly well, apart from a serious short when the neg terminal wire touched the frame and burnt out 2 wires. A pain, though a fairly easy fix.
What has me scratching my head is an oil leak. An oil leak I get, it's a Bonnie. It's where it is coming from that really puzzles me. There is a fairly constant drip/dribble from the bottom of the head stock, which does not make sense !
I get it's an OIF model, though the max oil level is much lower than where it is coming from, and I don't understand how it gets there, to then leak out, over pretty much everything, as the wind does a great job in covering pretty much everything behind where it leaks from.

Has anyone experienced this before, and if so, or if you have any thoughts, I would be very appreciative for some enlightenment.
Thanks a lot,
Edward
