DMF or SMF

Money no object dmf....because money is really no object
Personally I would go solid
 
Most people wouldn't notice the difference tbh. You hear horror stories about broken cranks and smashed gearboxes due to vibrations but I suspect most are unfounded.
If you go for a SMF, make sure the clutch plate is designed for SMF use. If so the damper springs will take the vibration out before the drive goes to the box.
A side effect of going the SMF route is improved acceleration in 1st and maybe 2nd gear. This is due to the lower inertia of the lighter single mass flywheel.
 
SMF Conversion kit is cheaper than a DMF. Mine has the Valeo conversion kit, which includes SMF, pressure plate, bearings etc. The clutch plate is a heavier duty carbon kevlar mix too. Slightly more vibration at very low rpm (like when trying to pull away in the wrong gear), but in normal driving it's no different, if anything better!

Hmmmm I dont know what to do, Its for a Rav4 but the principle is the same....

For £450 I can get a LUK DMF, Clutch, Clutch plate and release bearing...... The SMF kits vary from £100 to £450????:confused:

An LUK smf kit is £300 so for the extra £150 should I get the DMF? it should last at least 50k miles right?

As for vibration, I have always had vibration at low rpm or when the engine is under load, accelerating in 5th, Which im starting to think was the DMF at fault for a long time, probably so when I bought the car with 65k on it, now has 90k and has failed, the DMF was making scrapping noises, so I pulled it out.....

I read reviews of the smf`s causing vibrations etc....but I had the same with the DMF.....??

Will a new DMF give me a silky smooth ride....??

I just dont know?

Rav4 eat clutches and flywheels. Me mothers is on her 5th I think at around 109k miles. We put a blueprint kit in for £180 parts. Would have liked a luk one but that's all I could get in the short time I had.

No change in driving, she says it's better than before!

Mother needs to keep her foot of the clutch when driving, And might need a few lessons

She has only done about 10k if that and half of that was on the solid flywheel. The extensive service history and flywheels put in under warrantee told me the rest.

It's a weak point on the rav4 as i said, google it. She was very careful when she brought the car to get one with good main dealer service history and proof of recent flywheel change but she needed one anyway.

Dmf is around £800 if you want genuine if my memory's right,
 
Well mine made it to 90k.....Seems DMFs are a weak point on all vehicles nower days...

My clutch and clutch plate are ok for 90k miles, It seems like the springs have worn on the DMF, probably due to no lubrication, ie I cannot detect any grease in it at all, all that came out was lots of clutch dust, no doubt the grease has long gone, and the internals were just rubbing on clutch dust....its as dry as a bone, metal on metal squeaks......

where did you get the blue print one from? and was this SMF
 
DMF is the work of the devil. When mine failed on the Transit, they wanted over €800 just for the flywheel. I got a solid flywheel complete with clutch & release bearing for £150 which I fitted myself. Now It's not a Freelander but the principle is the same, there is a little more vibration at low revs if you let it slog, but the gear shifts are much smoother. I've done a fair few miles since the change with no problems.

No springs in the DMF's Ive seen, the 2 parts are bonded with a sort of rubber sandwich. the rubber breaks up and produces the dust which fecks the starter motor on the Transit:mad:
 
Hmmmmmmm maybe your right would explain all the dust, but the newer ones for sale now seem to all have springs..... Hope fully they have come on leaps and bounds in 10 years......As its looking like £437 for the parts......

Yeah the ones I have seen were springs. If your real lucky the springs can brakes and ruin your gearbox on other cars

Got my parts from euro car parts
 
There are a couple of designs of DMF. Some are made from 2 separate sections of steel (masses) with springs between, much like those found on a clutch plate. There is a variation of the design that uses bonded rubber between the masses, much like a standard crank damper. The rubber type is supposed to be better from a damping point of view.
Personally I prefer a solid flywheel. They have been in use for hundreds of years trouble free, god knows why suddenly in the last 15 years or so manufacturers have reinvented the wheel into a troublesome pointless lump?
 
Apparently they improve fuel consumption amongst other things

Think ill go for the dmf at that price it would be rude not to....a branded smf is not far off the same money...

Another interesting point made was that....most dont notice any difference with the smf as there origional dmf had fail damping effectively some time ago......hence they gradually get used to the vibrations etc.......I can relate to this.(mine may have been past its best when I bought it on 65k)......I would be gutted thou if the new dmf made no difference:(:eek:

I can't see how adding a massive lump of iron to the engine will improve Mpg, the opposite it true if you fit a lightweight flywheel to the KV6!!
The SMF is cheaper at the next clutch change as you don't have to replace the flywheel like you do with the DMF ;)
 
Well finally fitted the DMF only took like 2-3 weeks to do.....dont want to do another one ever....:(

But I have to say the drive now is totally different, no more vibrations at any speed/gear. I can drive at lower rpm speeds 1k gear changes with no booming or vibrations....All I can say is im glad I went dmf and not smf........When I bought the vehicle with 65k the dmf must have been faulty as now on 90k if finally went. ......Now I will Definatly be able to tell if the dmf is faulty or not.....such a huge difference....

Lets hope it last at least 40k :)

Hi any recommendations for a solid flywheel kit ?
Mine as just starting to slip in 5th under load 130,000
The joys the joys
