:: Any ideas?

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.

B750 and B1078 RR both gone now.

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: ???
True story.
