changing Clutch, Do I resurface the flywheel?
#16
So, who would you trust then? LOL

With few exceptions, almost any "mechanic" is going to tell you to replace the flywheel when you do a clutch. He can make more money that way. This is also his way of having an "out" if the clutch "goes bad".
Truth is, unless you have been driving with a slipping clutch a for a period of time, it should be fine. The second you pull the clutch off, you'll know. You cannot grind a factory dual mass flywheel either.

because the amount of time on the lift is the main issue this is a simple fix.
buy a replacement flywheel. if you need it when you tear the trans apart you have it. if not return it for a refund minus a small restocking fee.
the pros and cons are equal on both sides. from my experience working on these cars is diffucult and the chance of other things going wrong while doing something else is 50/50. if it were me i would replace it once and not worry about it. but then again i have had my car apart so many times i have lost count.

I am going to trust a master Porsche tech over a typical shop mechanic.
And the proof is in the pudding with my dual mass being good after my HP level, driving style and 3 clutches later. .

I think of it this way: New clutch and flywheel will have perfectly smooth faces contacting each other for optimal contact. New clutch on old flywheel would have clutch gripping an uneven surface. That's enough for me. Why cheap out with these cars?

I believe there are instances for any thing to go bad. And things do go bad..
I am sharing my experiences and what I have saw.. And I know how I drive and beat on my car to go through 3 clutches and still have the original DM wheel.. So am I Lucky then?? and the others that have theirs still?
Look at my signature with my power level,full mods with 18g..

Its being in the know from being around and seeing and doing,,
Not by others speculation to jump on others band wagon over a few mishaps...
Its all good here, sharing info and helping spending money as needed..

Ya this is not about money. If it has to be done I will pay to have it done. If it doesn't have to be done I will not spend the money for no reason.
There are so many members on this board who have so much knowledge I love posting questions like this and learning.

For those of us that are "feeling lucky" about re-using our DMFW I ask:
What should I look for when inspecting it? I am replacing my clutch because up-coming HP upgrades not any issues with it now. My car has 30k miles on it and I've had it since 5k miles.
Should I clean it up with ultra fine(1000grit+) sand paper? or anything else like that?
Thanks

Highly recommend you replace it. But considering you only have 30,000 miles you may be okay. But please make sure to use a feeler gauge and check for warpage.
Take a look at the first page of this thread where I made a comment about this before. I attached a link you may want to check out. In fact, make sure you read that other thread in its entirety. It's definitely worth the read.
On our high-end platform, I cannot reiterate how important it is to simply replace the flywheel with a new one (Whether it's a dual mass or a lightweight flywheel).
Good luck!

I would recommend replacing it for the peace of mind as well as not taking a chance of curbing the life of the new clutch due to uneven wear. If you need a LWFW, I have them on the shelf and could get it out today for you. There are points to both sides of this, but with how big of a job it is I personally would want all of the bases covered when it comes time to disassemble. Especially this time of year when shop time can be limited.

BTW, I love the feel of the CM FX350! More aggressive than stock but no steep learning curve.

OTOH, if the DMF was not exhibiting any symptoms of trouble before and the clutch wasn't slipping -- which raises the specter of overheating which can result in a grabby clutch operation once the new clutch hardware is installed -- and with a precision straight edge the DMF friction surface is within flatness specifications, I'd leave it alone.
Had my Turbo in at around 110K miles for an RMS job. Tranny came out and of course along with the clutch and the DMF. Clutch disc thickness was still at the new dimension (1.7mm). I measured it myself with a precision depth micrometer. The DMF was just fine. The only piece of hardware the tech replaced were the two small needle bearings in which the clutch control shaft fits.
