Dual Mass Flywheel Resurface?
Can the dual mass flywheel be resurfaced?
I finally got the old clutch, pressure plate and release bearing out of the '96 and the flywheel doesn't look new but it's not the worst I've seen.
The guy at the local NAPA store sez they cannot be resurfaced because they won't stay level when being cut.

According to the factory manuals - no, you're not suppose to do it. According to several old threads on this forum - some of those that heve tried, have regretted it. A new flywheel is very expensive (I know, I went through this process a couple of years ago) but pulling the tranny twice is no fun either.

Thanks a bunch for the replies. Now I just have to decide if I want to get a new flywheel or give the old one a try!

When you get your new flywheel, be sure to not cut corners and get a slightly different one than factory. You dont want to be in the shoes I'm in right now. :nonod:

Has there ever been an explanation as to why they cannot be re-surfaced, or is this one of those deals where 1 forum member says it can't be done thus the entire forum begins preaching it? I don't see why .005 or .010 will make that much of a difference on a hyd. clutch. Personally, I would say that alot of it lies in the quality of the machine shop.

Second, the surface that mates with the clutch is slightly concave, therefore resurfacing takes out this concavity and affects clutch to flywheel contact. Some forum members have said that a good machine shop can actually put this concavity back in, but it sounds like a sketchy procedure to me. Really a moot point since the flywheel will be ruined anyway.

There has been quite a bit of discussion about this, and basically it boils down to two things. First, the cutting oil used and the metal debris created during the surfacing procedure will damage the "internals" of the dual mass system. There's a rubber piece in there that mates the two masses together and it will usually be degraded by the resurfacing process.
