Dual Mass Flywheel Kit

[greenwidow]

I don't have a dual mass flywheel and don't want a car with one but wondered if this conversion is a good idea:-

There is an occassional visitor to the forum called HEMI who is in the motor trade and has converted his ( wifes? ) RAV to a Single Mass Flywheel. He is very much in favour of the conversion. There was a fairly detailed debate on the forum about the issue with some of our technical guys for and some against. Don't know if you found the pinned article ( top of the forum topics list ) about DMF's but there is a lot of very good info in there too, thanks principally to Anchorman. From a personal point of view, I wouldn't do it for several reasons but hope I'm never faced with having to make that decision anyway.

I've read someone with a Landrover did their own conversion on a failed dual mass flywheel. They welded the two parts together to form a single flywheel! Apparently it worked fine, until the weld failed a few days later.

Blimey! wouldn't fancy that. I assume that the 1st section of the flywheel ( nearest the engine ) is Cast Iron, so a structural weld for a dynamic load is a challenge, as is getting the alignment good enough and preventing distortion. If I was really, really desparate for a quick, cheap fix I'd stick it on a machining centre, line it all up and drill and ream/bore it for ( a lot of ) fitted bolts.

I will just say briefly, because i have said it many times before, we have been converting DMFs to solids for years with no ill effects whatsoever, and yes even welding them up before a solid flywheel was available, these are blackcabs fitted with the Ford 2.4 duratorque engine, and mine was converted 140,000mls ago, now try + imagine any vehicle that experiences more gear changes + stop starts than a hard worked Taxi, SMFs are OK Stew

sorry local hero, i've been a manchester cabbie for 30 years and have experienced the dfm problem on the tx2.

I changed to a solid flywheeland and afterwards the cab ran and sounded like abag of spanners.I am not alone,iknow dozens of cabbies that will tell you the same.so my advice is to stick with the dmf.

On French cars there have been cases of gearbox failure a few thousnad miles after fitting a SMF - the bearings inside the box start to grumble.

DMF's have allowed manufacturers to reduce weight and economise in many other aspects of the transmission.

As a matter of interest has anyone ever dismantled a DMF to see what's inside??:)

Probably the best explanation of what happens with DMFs is via:

I don't want to turn this in to a taxi forum but the tx2 has always sounded like a bag of spanners mainly due to timing chain problems, and anyone owning one has experienced DMF problems, along with lots of other problems, but back to toyota, I think we would both agree that Toyota engines should be better than fords, whereas the early 4.2 ravs have had DMF probs from as low as 20,000 mls + the latest models are experiencing EGR probs at very low mileage, now I hate cabs + M+O as much as anyone but considering the life we give them we don't "usually" get serious probs till about 100,000 + once sorted I hate to say it but they are comparatively quite reliable Stew
