hey guys just looking for some quick info.
believe it's time for a new clutch in my 92.
been reading and pretty sure Im still running an original dual mass setup.
correct me if i'm wrong, is that was came stock?
what are you guys using now?
I know its probably cheaper to convert to a single mass but I wana stick with the dual, if that's what ford put in it that's what I wana use. haha. anyway just wandering what would be a good stock replacement? everything is stock on my truck so I don't need anything crazy. also what size is a stock clutch? 12? and should I need to worry about replacing the flywheel?
any advice much appriceated.
thanks

 

if for some reason you want to keep the dual mass flywheel than you better get a new one. it will come apart!
me personally I am running a LUK with single mass, most have gone to single mass to get rid of the time bomb (dual mass flywheel) a lot of people here on FTE are running the valiar clutch, I am ok with the LUK and tow heavy with it, just have to be nice to it. I have about 80,000 miles on it so far.
when you go to single mass you will get noise from the transmission, it is the reason ford used the dual mass. adding 1 extra quart of trans fluid dampens the noise. as for being "right" to have a dual mass, ford changed their mind later and went to the single mass.

 

Put aside some money to replace your tranny case (if you can find one) when that dual-mass flywheel comes apart and grenades it. Think of it this way - one of the best engines International (NOT Ford) ever made, mated to one of the best transmissions ZF (NOT Ford) ever made, and what does Ford do? They put a time bomb (DMF) between them. Ford didn't build the engine or the tranny; why would you take their word for what's best between them? I bet if either ZF or International could say so with impunity, they would say Ford should NOT have set up a dual-mass flywheel in this application.

 

I converted to a single mass because my dual started rattling really badly, sadly I still have a lot of meat on the clutch and the pressure plate looks amazing. The conversion kit was about $550 which included the single mass flywheel, clutch, pressure plate, throw out bearing, and pilot bearing. To get just the dual mass flywheel through Napa, was about $1200. The only difference in performance between the two? The dual mass absorbs slightly more vibration from the engine so you don't get the gear rollover noise with a single mass. All comes down to will the noise bug you. And if you are concerned about noise you've got the wrong engine

 

Hmm, a little gear noise..... hmm... my tranny grenading.... hmm.... decisions, decisions....

 

That and the gear noise is only in 1st gear at any speed under 15 mph

 

 

Holy hell how did the block look after that?

 

I dunno, I got it like that. It was mated to a running engine, but I have no clue if it was a replacement or not.

Dumb thing is even after that experience the PO put a new dual mass flywheel back in....

 

Block is cast iron, doubtful a DMF explosion would hurt it.

Fixed....

 

thanks for all the input guys. sounds like everyone is convinced the dual mass is junk. only reason I was thinking of keeping it is because the truck has 180,000 on it an either 180,000 or 120,000 on the clutch. I got it from the second owner and he got it with around 60,000 on the truck and hadn't had it replaced yet. either way I just figured even if it lasted 120,000 if I can get another 120,000 out of a stock replacement why not just do that. also can't forget the possibility the original owner had it replaced the a single mass tho.
been doing some more reading and u all have persuaded me to go with a single. question though. do I need to worry about what size I should get? I don't do a whole lot of towing with it never more than 12k every now and then.

 

FWIW I have 350,000 miles on my dual mass flywheel. When I did the my ZF swap in my current truck I took the ZF and DMF from my last truck. Works fine for me and that way it only cost me $250 for a new clutch. Not sayin' it won't grenade, but I opted not to do the SMF upgrade. On my particular truck keeping costs down is important.
