Can I machine a dual mass flywheel?

[pjdm1980]

I'm doing a clutch on a 2000 VW Passat with a 2.8 V6 and ran into a problem as I've never delt with dual mass fly wheels. My fly wheel has some hot spots and I've searched the net and come up with some mixed answers such as
- You can but it will shorten the life of your clutch
- No you can never machine a DM flywheel and so on.
So can I machine the dual mass flywheel and if not can I replace it with a standard flywheel?

I don't think you can machine a dual mass fly wheel. I think its like the manual GEN3 V8 Holdens, see if you can replace it with a standard fly wheel.

You can do it how ever it isn't recommended.

I'll call a few places in the morning I'm just a bit worried about availability of a normal flywheel being a VW.

Why is that?

[wraith]

Just a lot of hassle to get it balanced as far as I can remember. Most places won't go to the hassle.

[pjdm1980]

OK thanks for that dude.

[wraith]

By all means give it a shot could be different for those model cars but I doubt it.

I'll ask some shops tomorrow but I'm pretty sure you'd be right from what can find.

Machine shop/engine re-builders/brake and clutch place would have the best answer i would reckon man

[pjdm1980]

Rang around and found one shop that said they might be able to depending on the condition of the flywheel, so I took it in and they said-
1. The internals where to far gone
2. It was a pressed on version so they wouldn't be able to anyway.
VW dealership $3300
Clutch Australia $1300
IMP parts $ finding out now.
No one that I've called (a lot) make solid flywheel conversions.
I now know why I've always steered clear of European cars!!!!!!!

Some of the clutch kits for vehicles with a dual mass fly wheel often come with an option of a conventional flywheel due to cost of replacement and disposable design of the DM.
Nissan patrol is one example.

Yeah, they can be a bit pricey.

I would suggest you see about importing one from the US. Probably be alot cheaper than what you would pay here.

Good luck.

All Gen 3 and 4 ran a solid flywheel, even the VE's do.

NO.

No they don't. Pretty sure I have replaced a few clutches in GEN3's before and they were all dual mass flywheels, and we replaced them with solid flywheels.

[Biznatch303]

The countless numbers of rear mains and clutches and slaves that ive replaced from VT to VE, have all had solid flywheels, never have i seen a dual mass. And this is working in a holden dealership doing this work. Always solid the ones ive seen.

Ok then, either the ones that you did were already converted or maybe I am wrong.

But I know for a fact that my my cousin's VY SS and my Dad's VX SS had a dual mass flywheel.

My cousin bought his VY SS brand new, his clutch was worn out about 120,000kms and he asked me to replace it. When I pulled it all down it had a dual mass flywheel and it was from factory.

My dads VX SS, he bought second hand with 130,000kms and the clutch was worn, pulled that down and it also had a dual mass flywheel.

And there has also been a few come in to work with blown slave cylinders and they also had dual mass flywheels, I didn't work on them but I still knew about them because they told me how much it was going to cost to replace the dual mass, so the customer wanted us to replace it with a solid flywheel because it was about half price.

They're supposed to be dual mass. Holden's clutch kit comes with a new dual mass flywheel and they're not cheap.

Back to the golf (edit passat). If you convert to single mass, ensure that the clutch plate has clutch springs. Otherwise if you load it up fast without some movement in either the flywheel or the clutch plate you can rip the centre out of the clutch plate.

Ok sorry mate, you were right. Apparently they did come out with solid flywheels. I don't know why it cost so much to replace them though, and maybe the cheaper flywheel was just a different type. Oh well, you learn something new everyday.

It turns out that the Ecotec and Alloytec V6's have a Dual Mass Flywheel.

It's all good

After a lot of hours of searching around I found a supplier in the states called South Bend Clutches that can do a solid flywheel and heavy duty clutch delivered to Australia for $1300, oh I hope it was worth the hassle! LOL
