Dual Mass flywheel - replace or not?

patrolman pete · 15th February 2011, 13:32

Hi, that day has arrived that we all dread ( not hgf or belts! c'os she's a diesel) but my clutch has started to slip under heavy throttle. I'm pricing up the parts and are using LUK components as i believe these are what MGR used. I can get my trade discount at Europarts and a 2 part clutch kit is £138 inc vat and the slave is £145.19 inc vat too. However they are recommending that i also change the Dual Mass Flywheel which is £378 inc the vat! Total £661.19 for parts alone! Can anyone advise if it is really necessary to change the flywheel on every clutch change? The car has done 108,000 mile on her origional clutch and there are no rattles and the pedal feels great

PS i'm getting a garage to do the hard part for £300 labour if i provide the bits.

I would advise YES I did a clutch change on my 160 V6 and ended up with massive vibration, ended up having to strip it all down and start again,at much cost, so do it now whilst you have it stripped down and then you are sure about all the work

At that mileage I would agree that with the whole lot out, it would be worth replacing the DMF too.

Why not just wait until it comes out and then check it.

If it's in tolerance then leave it as it is.

More are used again than are changed.
If you are a sensible sort of driver and don't race people away from the lights then it's probably OK.

Colvert.

Bit a generic DMF question, why do some marques seem to suffer more with failing (by failing I mean rattling) DMF's than others...? Is it by design of the DMF, or the engine/drivetrain?

Sorry, not a mechanic so maybe a stupid question but..... If it's fine before and just slipping why would it rattle or whatever after? How can you tell before you change a clutch if the dmf is duff? If no symptoms before, why would you afterwards? Me no understandy?

never had to change a DMF on a 75 yet they are fairley robust but there will be a first one day the price for fitting is a bit steep we fit for £150 labour or supply and fit for £400 inc vat with 2 year warranty

not including DMF
