Here's the short story...

New clutch plates installed along with a custom engineered bronze clutch bush (couldn't be had any other way).

The new clutch plates were provided by the Club (Big Up to Dorian & Jerry) and are the Surflex 'unipart' plates. The old clutch plates were, well, different.

The mechanics have had the clutch apart three or four times now and each time when they reassemble the clutch it appears to work until it heats up and the suddenly it doesn't work anymore.

They don't seem to be getting anywhere with it and the constant dismantling/mantling isn't improving things.

Does anyone have any bright ideas ?

Cheers.

Geez, Jon, you are having more than your share of trouble with the TR. I hope one of the guys figures out what's wrong.

Hi
I have had the same problem with my Ducati clutch i.e works fine until warmed up, so fitted thinner metal plates to cure problem.

I would think that the clutch plate pack is too thick.

How much adjustment is left on the pressure plate?

Are the metal plates new? (Warped).

:: Thanks

For the steer Keith,

I've suggested that the mechanic look at the two sets of old plates and find the thinnest and flattest and swap it out for the thickest of the new plates.

Hopefully they'll eventually work out a combination that will provide the requisite clearance.

I thought that a ball bering went in before the rod to help with heat transfer. But what do I know about these things.

Okay, they *seem* to have reassembled the clutch finally although there's some troubling noise and stalling..... *sigh*

If it's not one thing, it's yer mother....

And still they can't reassemble the thing correctly! That's it. Come Saturday I'm going to get it, cause a scene no doubt when I start refusing to pay the full price for failure, and take it to Motori di Marino where I should have gone in the first place! $**********!

What can I say? Six months on and £££s later already and I can't find a competent mechanic in London to work on the old lady. WTF?

It fails when it gets hot ? ? ?

Metal expands when it gets hot. The only way I could see the metal plates failing is if they are broken and expand when they heat up. In my experiences I've had springs that lose their tension when they warm up. That's the first thing I'd replace.

Was that the same bike shop that did your rebuild, Jon?

I don't understand how some of today's mechanics got their degree.

It's like one of my trained-as-a-mechanic mates once said: we can't fix the broken parts anymore. We plug the car onto a computer, the computer tells us what's wrong, we jank the part out and put a new one in. That's it.

My brother took his old Beetle once to a VW-Audi specialist to have the wheel bearings changed. Reply from the garage owner: sorry, Sir, we can't do that kind of job. You got to take it to someone who knows these things.
He: :wtf: ???
True story.

Hey oepie, unfortunately that's more & more common & a sign of the times - if it doesn't have a diagnostic plug forget it. I live next door to an old Sicilian guy who used to work for a company (before he came to Australia) that used prepare race cams & crankshafts in Alfa Romeos & Lancias. He was teaching my son the fine art of bearing removal (in one piece) from all the pivot points on his downhill mountain bike, I fear when those guys are gone, a decent mechanic will be more sought after than a brilliant neurosurgeon who will a dime a dozen, everybody wants to be a professional these days!

Sorry I can't help you Sheriff, if it's any consolation I certainly understand & sympathise with your frustration.

@MVista & @Oepie

Well I called Pietro from Motori di Marino and he is happy take the old girl back on Saturday to work out a) what the hell is really wrong and b) what if anything the guys at Big Jims have done (the good, the bad & the ugly). That's about an hour and a half drive from London so I guess I'll call road recovery and have it transported.

The interesting conversation will take place on Saturday afternoon. Exactly what am I expected to be paying for here? I provided all the parts except a clutch bush which had to be engineered. Okay I'll pay for that, plus oil and whatever else was purchased. As to paying for labour should I really be paying for failure here? As a matter of goodwill I would pay for some labour costs but it'll be very interesting to see what they attempt to charge me. I've got a feeling this could end in dispute.

After all, I could be told later by Pietro that they've screwed something up badly especially viz the clutch plates or that the bush they've had engineered is wrong &c...

Sure is going to be an interesting conversation. I'll let you know what happens.

Thanks again.

Jon,

I hope the guys at Big Jim's are half decent and will say: sorry but we can't solve it, just pay for the parts we used.
It would be the proper thing.
In some job sectors there's this saying: no cure, no pay.

I hope it doesn't end like my Centomila's engine rebuild. The poor thing is still standing in my garage since September cos
1. those mechanics here screwed up the gearbox reassembly so I dare not ride it because the damage could get worse,
2. I can't have it properly rebuilt before an independantly appointed expert will have tested it and written his report.

Fortunately I can keep myself busy with some other toys. In the meantime I'm waiting and half hoping that the judge will be on my side. From an objective outsider's point of view, he really should be.

Well I manged to retrieve The Flying Ant on Saturday. The guys at Big Jim's were pretty good about the whole thing as it turned out..... They put their hands up and admitted they hadn't been able to fix it and charge me £50 for various bits'n'bobs used in their attempts. Made mee feel a bit sorry for them really but in all honesty I was relieved we weren't in for a showdown.

I was able to ride it away even though the clutch problems soon made themselves known. Managed to 'breakdown' in front of a lovely pizza joint in Ealing where I sat for a couple of hours in the sun drinking Pino Grigio, occasionally interrupted by the usual series of phone calls from the AA. "No, you will not have any spares for this bike," "No, you will not be able to fix it by the road", "Yes, you will need to send a trailer or van..." and so forth.... All in all the best breakdown I've had....

Now the old lady's with Pietro at Motori di Marino for a proper seeing-to. I've not heard from him yet but hopefully things won't be too bad.

Thanks for help & words of advice & support....

Well, if you have to have a break down you certainly got it absolutely right :laughing:

Looking forward to hearing of a successful ending & more-so the whys of what went wrong.

All the very best & good luck :)

I have the good fortune of having a father who has been a BMW mechanic for 35 years. It's nice when I'm trying to fix the bikes or I have problems with the cars. All the new cars are all drive by wire it's insane the training the techs need. I recently received a YouTube video from a fellow collector that you Guys might find interesting

Fantastic vid Alex, thanks for putting it up. I think it kind of deserved its own thread under the general section - I think EVERYONE ought to have a look at it.

What he says is so true & frankly also sad.

I REALLY admire that man and what he had to say. I don't care whether it's carpentry with hand tools, cabinet making, gardening, metalwork, upholstery, furniture restoration or whatever .... the same ethos applies and the need for there to be individuals who continue to demonstrate their love of what they do persists. Wonderful!
