DUAL MASS REPLACEMENT ISSUES FOCUS TDCI

[octo0072000]

DMF clutch centre is solid no springs the DMF is the springs

solid flywheel clutch centre has springs

 

[paceman1]

so do the dmf clutch kit weigh the same as a normal set up clutch if there different there will be issues
harmonic vibes can be sorted by fitting a fluid damper

Sure my DMF Astra clutch had springs when I changed it.

Dark now but will look in the scrap pile tomorrow.

I'm actually going to take more notice myself in future.

The one i took out of a Mondeo a couple of months ago defo had spings. One had either worn through the back plate and then broke or it broke and came out of the back playe not 100% on which way round it happened

Thanks for all the replies folks you have been great - I did think about welding it (Migmag) but issues with balancing etc. The mechanic only wants £150 to fit it, it's the long-term issues for 'erindoors most bothered about. Is approx.100k the normal span for DMF then? If so most likely get DMF again, read today that the quality of LUK may have gone down a little when I googled focus 2.0 TDCI flywheel though! Again cheers to all contributers.

I may not post much but I do read it every night, otherwise I feel a little hard- done- to!

100k miles is a fair estimate. Still fitting LuK daily myself with no complaints. I refuse to fit anything that isn't LuK, valeo, sachs or on jap stuff ADL blue print, when it comes to aftermarket clutches or flywheels

1 at 98k, one still going at 130k ... so yeah that kind of ball park..

petrol engines onvert to sigel mass flywheel ok, pump diesles some of seem to convert ok, common rail diesels seem to need the DMF the gearboxes can make some nasty chattery noises without and i've heard of crancks snaping.

the people who destroy DMF's are overly steady drivers who insist in being in 6th gear before 30 mph and refuse to rev the engine in the misguded belief that there saveing fuel by not useing the turbo

Mine is at 145k on original clutch & DMF.

It is nearing time to replace the clutch.

At that mileage I will do the DMF as well.

I always wondered what kills them. I had a seat toledo TDI with 240k miles on the clock with the original Flywheel/clutch, was still going strong even when I sold it.. Some have even gone to over 300k with the original clutch/flywheel. It did develop the slightest vibration on idle at 160k and never got worse.

My Citroen C8 will not run at 30mph in 6th gear
around town 5th and 6th gear are are no use at all

So I checked today.

It sort of has springs in the clutch plate. Not as big or as many as in a standard plate & they seem to be in a plastic enclosure.

that's interesting as far as i know the early DMF the clutch centre plate had no springs
looks like not enough spring then in the DMF so add to the clutch so now two lots to go wrong instead of one

Hello all,
looking for some advice. The Mrs car C-Max tdci needs a new flywheel. The dual mass one is slowly becoming more than dual. Have seen the kit for it around £400 (Sachs) but motor factors quoted £500 (unknown) for kit - oh and what are LUK like as a product/brand? Back to point - have been told that the conversion from dual to single mass flywheel causes issues in time e.g. vibrations eventually knacker fuel pump/engine overtime requiring new engine at £1500.

Anyone heard/know about such issues?

Thanks for looking

Over the passed 3 years I have weldedup 5 DMFS a transit for a m8.. its still ok 2 years on..a volvo v70 d5 my own still ok. a vauxhall astra deisel 1.9 150 bhp still ook 40000 miles later.. DMFS ARE JUST CRAP WHOEVER INVENTED THEM SHOULD BE WHIPPED!!

done 30k on a solid flywheel and clutch from eurocarparts in a chipped tdi golf estate,and i hammer it every day.no probs,although slightly noisier than dmf but good bit cheaper.

 

[HughF]

Done 70k miles on a solid converted mk7 transit 2.4, knocked 4th out 5k miles ago, exchange gearbox sorted that (but I think it was dying when I got it from rac)...Done 50k miles on a mk6 2.4tddi, no problems.

I would never fit a dmf back to any of my vehicles.

What kills DMF is driving like a pensioner and short shifting - expressway to wrecking them...better give it the beans 2.5-3K, get some decent revs up, then its got centrifical force to keep it spinning between gearshifts...

Most of them I've heard of going bang are driven "carefully"...no coincedence...

I've replaced 2 DMF's now for others, both drive like pensioners (they actually are pensioners) and neither of them ever revs above 2k, I've tried telling them they are killing it but they both say "I've been driving diesels for years and this is how you drive them for maximum life & economy" they won't listen when I tell them the diesels of their era and today's are totally different beasts.

As this is a welding forum I'm surprised nobody has suggested it - weld the 2 halves of the DMF together to make it a solid flywheel, get it balanced if you want and stick it back onto the car. I know a mechanic who does it regularly without a problem!

The first one I did the owner can weld, so he stick welded it, I spun it in the lathe at work and it ran true but when fitted back in the car it was awful to drive, fit a new DMF and it was fine.

175000 miles and counting from my passat tdi 130 (+ !) on the original clutch and dmf, I have a very heavy right foot! Sadly it's just about to get replace by a Nissan Qashqai, it's been a brilliant car

that will be a bit awkward to get a shoe on
