Dual Mass Flywheel wear

[Van Black]

Goo'day to y'all.
I'm in the middle of rebuilding my engine and just wanted to ask: how much play would be considered normal for the flywheel?
Mine moves rather easily about half way from neutral to full lock, in either sides. From what I've gathered on the interwebs it's too much.
From what I saw on parts sites 16 degrees would be normal play.
Another thing worth mentioning would be the fact that the car jerks when I change first 3 gears and no, I'm not a manual noob.

I have a Clutchmasters steel single mass flywheel I can sell you for cheap.

From everything I read about the car before buying it the dual mass disappears when the clutch does . no one pays the ridiculous money for the DMF. I will be interested on what people here have done.

[Van Black]

The clutch and the pressure plate has already been replaced. Car should be around 300k Km. DMF also looks like shit, I just took it off tonight.

Appreciate it but the cost to ship in Europe will probably kill the deal. I'm digesting it though

I bought a used low mileage DMFW years ago as a spare and still have not replaced my clutch, but that could be soon. Does anywhere resurface them?

[aluthman]

Resurfacing them generally isn't the issue. They tend to come apart as they get old and are subjected to abuse.

Dual mass just absorbs some of the impact from clutch engagement, right? I think I prefer single mass even for daily driving as it's much more predictable when and how it's going to grab.

they're suppose to also absorb vibrations from the engine while it rotates. clutch engagement is what worries me on mine, it otherwise seems okish...depending on where you read. The surface is worn though

Yea I'd want to go single mass. Luxury is nice but not if it messes with my pedal feel.

So, anybody know what's the normal play for a new DMFW?

[Charles.waite]

I would think at 300,000km that Flywheel is toast.

FWIW, I swapped my b6 1.8t to a valeo single mass kit and LOVED it. Exactly like stock, super smooth engagement, and was $375 WITH the flywheel.

Valeo has yet to develop a similar kit for the b7 which is a huge bummer because its the perfect setup for a lightly modified car (think stock turbo tunes).

[Theiceman]

if I remember one of the downsides ( if you can call it that) of the SMF is its lighter and the revs Hang up between shifts, making shifts a little trickier, have any of you noticed that who have done the conversion ?

[aluthman]

Lighter fw will make revs fall faster between shifts. Using a heavy clutch can cause hangups when shifting but that's independent of the fw.

$60 USA from New Jersey to Europe. Just sent complete clutch kit to a member over there Ove. He has the info he found the carrier (jet carrier) grab it from Adam have it delivered. I wrote up the bill through my business and I'm not sure if he had to pay too much for the duty. But it cost me more to ship within the USA then overseas. I had mine resurfaced b4 sending. As per advice from jhm and drakelore it wasn't an issue on the single mass. It only gave the new owner 100% completely new surfaces for the kit I sold.

This. Revs were ever so slightly faster, but the Valeo SMFW was only 2lbs lighter than the stock flywheel. The ONLY negative I experienced was a sort of resonant rumble in the drivetrain at low rpms at WOT (>2500rpms in 5th or 6th gear). Also here was slightly higher idle NVH but that could have easily been due to the 034 Street Tranny mount I installed at the same time as the new clutch.

There were no major deal breakers in my book and if I still had my b6 I wouldn't hesitate to replace it with the same kit again. Also keep in mind the 1.8t is a much more vibration prone engine due to its lack of balance shafts. Couple that with my b6s major issues getting the engine/Snub mounts aligned properly (never did figure that out, but I think the engine subframe was tweaked or maybe a subframe bushing was sagging since my snub was always bottomed out in the snub cup) and I suspect the NVH i had was due to some other issue in my car, and wasn't an issue with the clutch or flywheel.

This is the 1.8t Valeo kit I'm talking about for reference: https://www.ecstuning.com/b-valeo-pa.../52285615~val/

LUK makes a stock replacement clutch and flywheel for the b7. Pervious owner put one in my car. I'm sure any shop with worldpac or another parts supplier can get them.

I've already went for a Luk one. Oddly, the one in the car is also Luk, so unless it's been changed already......

Wow, shipping a LSD would have cost about 300$ if I remember right. That^ price is a steal. Unfortunately I've already ordered a DMFW since all the singles I could find were twice as expensive.
Maybe later on if I decide to go whack on the car

[Van Black]

As soon as the new FW arrives I'll make a comparison between old and new as far as play goes. If I'm not happy with it I'll go SMFW
