has above has any body replaced there duelmass flywheel with a solid one
it seem to make the cluch kit alot cheaper and my just gone

yes its done all the time ...the same clutch is in the transit .. just make sure you order the right kit they are widely available.
if your clutch is gone more than likely the fly wheel is knacker also as its a common problem

Is it a TDCI ?
My brother tried it on a 08 corsa cdti it worked alright but made the engine sound like a tractor or should i say an older non common rail diesel engine.
I think the only reason they are on modern diesels now is to make them sound better.

If you find debris on the starter drive the flywheel is about to become history.

Also the maximum allowable amount of free movement allowed in the flywheel is ISTR 25mm/1 inch with no excess looseness or clicks or crunching noises.

Personally if a 4 in 1 solid flywheel kit is available I would skip the checks and fit a 4 in 1 clutch kit.

IIRC, Valeo started manufacturing direct replacement solid flywheel kits some time ago.

They really two purposes they act as a torsional vibration damper and as a drive line shock absorber to even out the torque fluctuations created by each firing stroke. By evening out the torque fluctions a DMF allows manufacturers to getaway with using a lower torque rated gearbox and drive shafts.

In modern diesels they can just about be justified but when used in petrol engines they are just an added complication.

If going to a solid flywheel, bare in mind that there's been reports of Mondeos breaking the crank due to the lack of damping. Ensuring a damper front pulley is fitted is recommended to try and reduce this. Not actually seen one do it, but it's been reported in the 'trade press.

Don't quote me on this but I'm fairly sure I've heard of problems with crankshaft damage if you don't have the dual mass thingy to absorb some of the shock load from modern torqey engines. I don't know if its common or just possible though

It amazes me how long people keep driving on a knacked DMf . I did a vectra last week that was so bad I had to cut the centre out to get at the flywheel bolts . Shop around as there are some good deals from the factors , euro car parts seem to be keenest on price at the moment .

How do you know when DMF is going or even gone?

They usually start rattling, especially at idle.

My TDCI Mondeo has always been a noiser engine, compared to a friends Focus, wthe exactley the same TDCI

does that mean my woes will start soon .....................

Other thing to check when doing the job is the condition of the big bush on the lower engine tie bar --- an expensive part but you can rebush them using a Peugeot diesel engine mount bush which costs about £10 and is slightly stiffer but you need to enlarge the hole to 12mm and pack the width with washers.



(How i know this is the Mondeo lower engine tie bar also fits the Rover 75s which is handy as the lower engine tie bars for diesel 75s are like gold dust.)

The service limit angular free movement on a DMF is surprisingly high I have seen some web pages quoting 50mm/2" as acceptable I have even heard tales of new flywheels with 50mm movement.

The new clutch will probably be a type with springs in the centre hub these last longer than the original LUK solid design which tended to suffer from fatigue failures and the springs help absorb any shock loads to the DMF.

The motor factor may offfer you a "National" brand at a keen price I have found these OK and prefer to LUK.

i have a dmf sitting in my garage..... available if you want it

this is the part im looking at
eBay - The UK's Online Marketplace

Fitted a kit from that seller to my 03 tdci estate approx 25k ago no noticeable noise increase clutch feels fine and as an aside ford now do a sanctioned single mass replacement for some transits so I take that as the green light.
