Clutch kits

[Steveo]

Hello all and merry Christmas
General enquiry on luk clutch kits

Is there any difference between the friction plate ,pressure plate and release bearing on a solid mass flywheel compared with a dual mass version ie are they interchangeable components ?
Regards

All I can tell you is that the clutches and clutch kits are different depending on the engine it is being fitted to - and as most of the X7 have Dual Mass Flywheels apart from a few early petrol engines, these too are different according to engine. So there's no comparison as there's no single flywheel versions to compare with on a diesel.

I know about the dual mass, I was just wondering if the three parts (not dual mass) are the same for the single mass as well as the dual mass
But if there's nothing to compare against I guess that's it
Thx

Yes, that's about the long and short of it

Theoretically the friction plate at least can't be the same as on a solid flywheel the cush springs are very noticeable. The damping is done within the flywheel on a DMF vehicle and the friction plate is therefore solidly attached to the splined centre.

No, they're not the same type of friction plates.
A DMF friction plate does not incorporate springs - the shock-absorption is in the DMF flywheel.
A traditional or SMF friction plate is sprung, as the flywheel is solid.
You must not mix the two.

God, can you imagine the driving experience if you did? Sprung plate and DMF might make for a very smooth transfer of power, while a solid plate and SMF might make for a very ABRUPT transfer of power!

Hill starts with DMF can be less than slick anyway, but can you imaging doing one with a "double twangy" in the drive train?!?

Thank you for all that information, might come in useful in the future.

That effect could be enhanced even further by replacing the CV's with the good old rubber doughnuts so loved in the Lotus Elan!!

Cheers guys
I was only asking because we went to Scarborough a few weeks ago after the car had been stood for 14 days do to covid (me not the car) and the clutch was definitely slipping on occasions maybe twice there and once coming back .
This only happened slightly as the revs increased on acceleration the speed didn't increase at the same pace.
However this now seems to have rectified itself
I have tried to accelerate hard going up a long steep hill on numerous occasions in various gears and no slippage has occurred.
Just wondering now if it was because it was stood for the 14 days

Strange

It’ll be either clutch and or DMF. If it’s started to happen it will get worse. You’ll notice it more when putting the power on when in 5th or 6th gear.

Be prepared to have both replaced at about a grand. If the DMF is on the way out, be wary as it will run the risk of breaking up and causing periphery damage if allowed to do so.

When mine started slipping, it started off just occasionally, but got more noticeable quite quickly after. Not long after I had them both replaced, (and I did see the worn DMF and clutch), I started getting slipping again after about 11k miles. Turned out the second slipping issue was the crankcase oil seal had gone, leading to oil on the clutch.

Had to have the clutch replaced again which I paid for, but the labour for the job was covered under extended warranty.

Cheers Marc what mileage was on the car at the time ?

The auto adjusting clutch on these is known to be a bit rubbish at auto adjusting. It can mostly be pursuaded to auto adjust if you give it a bit of high revving abuse in 1st / 2nd / 3rd and by doing some harsh downchanges. This in addition to the rubbish DMFs and leaky crankshaft oil seals that some come factory fitted with.
Mine has been leaking for a few years now - I just keep an eye on it, and it has also been slipping due to the auto-adjust being lazy for many years now.
