Dual mass flywheel to single yes or no

[chriz1]

I'm going to be changing clutch on daughters corsa d 1.3 cdti. Is a dual mass to single conversion advised?
What's the difference apart from cost some folk say they don't see a difference others say its horrible with more virabtion etc...
Cars done nearly 100k but no sign of failing flywheel

Some people get on ok with it others lots of vibes, what is the difference in price?

I believe you can get SMF kits which are "silent" -

Stick with the dmf these engine don't have many dmf.issues


I'd be looking at a cam chain. Soon however seems to be the weak link on these

I've done a few SMF converstions on VAG stuff

MK1 Leon TDI PD150
MK2 Leon TDI PD170
MK2 Leon Cupra R (petrol)
MK2 Golf TDI

Always preferred the feel of the pedal etc, most have been fairly silent apart from the PD170 which ironically had a "silent" kit on it and was quite loud.

OK thanks all. What's the acceptable play when I get it all apart

Google is your friend.

Can't really compare different makes to each other...because they're all different.

On a small horrible diesel though, I'd say it would need all the vibration damping help it could, stick with the DMF if you intend to keep it.

Not sepcific to the Corsa, but I've seen a few conversions ending up in tears down the line, so wouldn't advise.

Manufacturers fit them for a reason.

Well that is debatable.

But when the entire package is designed to have them....removing them is not a great idea.

[chriz1]

Well clutch all changed was suprised to see a single mass flywheel which I assume is standard as it was the original vauxhall clutch unless the dual mass has been changed without changing clutch can't imagine it mind

Skoda started fitting SMF's to the Octavia when they had many DMF failures, think it was the MK1 generation.

How do they make a flywheel, which is just a solid lump of metal, "Silent" ?


This DMF or SMF topic has been done to death here and on every other car forums.
My take on it is, if it comes with a DMF keep it. All these modern engines are designed around a DMF. A DMF has springs that "Give", take that away something else will have to "Give" ? OE replacement DMF kits are very much better than they were a few years ago.

Do single solid lumps of steel generally make noise ? Or does that require more than one piece ?

The clutch plate has springs instead, I ran a "silent" kit once.

Same, the 1.9 diesel found in fiat/VX/Saab. Doesn't seem to like it and can cause engine issues.

Not just about pedal vibration, it's what it sends back into the engine
