Clutch, again

[Guest]

Hi all, last year i fitted a new 3 piece clutch from paddocks, i also replaced the bearing carrier.

My clutch has now started to act like a switch again and has become juddery!:X

I intend to remove my gearbox hopefully next week, anything i should pay particular attention to? I've only done about 1500 miles on this new clutch.

Would it be worth fitting a grease nipple to the bearing carrier and drilling a hole in the gearbox whilst its out?

Thanks, Jason

when I had my car rebuilt several years ago, I had the choice of auto or MOD, I went for the Auto to keep as was, I used to think that I had made a big mistake but the more I read about the MOD and the clutch the more I think I made the correct choice.

sorry Jason to have gone off piste.

Hi Jason

Ive got a noisy release bearing after similar mileage.

Can anyone recommend the best brand of clutch bearingor any tips on installment.

Why do certain bearings need renewing after this small amount of miles?

Thanks in advance for any advice.

What's the make of the bearing you fitted? OEM is RHP which is still avalable.I can only imagine it's a cheap bearing or it's been fitted out of alignment

I can only suggest you read the relevant section in the Technical Reprintson the SOC website, members section. There is some help there about clutch problems.

nib, is your car fitted with the Triumph Stag V8 or a Rover engine?

The clutch bearing wears out quickly becasue the box wasn't aligned properly, therefore it runs concentrically. 1000-1500 miles is the right amount of time forany grease to wear off the bearing carrier and show you if it is aligned/assembled properly. I put a grease nipple on my carrier and machined a hole in the gearbox to allow access, though I have not had to use it yet, the problem is if you have to keep pumping grease into your clutch, eventually some of it will find its way onto the clutch plate and you will end up taking it out again anyway. The best thing is to assemble very carefuly with absolute care in accurate alignment of the box. Replace anything that is worn or could be worn, cross shaft sleeves, cross shaft, trunnions etc.

Ive just had the same problem mate, its a right old bugger!

When you had the bearing carrier replaced did you replace the pins in the fork too? thats what I was advised to do aswel. Also check that the gearbox nose extension isnt worn and letting the bearing carrier rattle.

From reading old posts on this board as well as advice from other places, it seems that the problem, as others have mentioned is getting the clutch aligned and then getting the box to line up.

If you want to look on the bright side at least your clutch lasted erm... around 1500 times longer than mine did (all be it mine is a different problem to yours)

I find that the Borg Warner Type 35 is a pretty good make of clutch ! Martin.

Every one keep going on about aligning the box /clutch ,When ever i've done a clutch on other cars the alignment was needed to get the gearbox shaft with spline through the clutch drive plate and then into the bush in the back of the crank .once the box was bolted up and the clutch was operated the clutch plate is then free to find its own position .I don't see how alignment comes into play after the initial fitting ,Surely the box and engine can mate together in only one position with a couple of dowels i imagine .so what can stay out of alignment?


The only thing i can think of is dirt between the engine and the box ,but that would be just obvious and wouldn't keep happening to so many people.

Stag rear plate doesn't have any dowels ! They used slightly different bolts, if they were once replaced in the wrong holes you're lost, the box bolts up out of line with the crankshaft. Martin.
