View Full Version : Flywheel question

02-12-2008, 04:37 AM
Hey folks, got the gearbox off the car today. Noticed the flywheel has a bit of play in it so can move it left and right a little bit to cover a little of the bolts.

Does this mean I need a new one? I have read that people always replace the flywheels when doing the clutch.

Nope. Slight normal is movement.

Go to southbends website and they have the detials for the test. Some play is normal, but to much means you need replacing.

Cheers mate.

I will read up on the southbend page.

I can move mine just over half a bolt either way.

Also is it ok to get a duel mass flywheel skimmed? Just as they are balanced.

Which part of the page is the test on?

Bottom, it will say testing dual mass flywheel or something aroudn the installation.

Cheers mate, I will do those tests tomorrow. I hope mine is ok.

Just need to find out if its ok for it to be skimmed now?

Oh just noticed at the bottom of the southbend page it says.

f the DMF passes these inspections consider taking it to a flywheel or clutch shop for further inspection and possible resurfacing.

If your DMF has 125K don’t expect to get the same mileage with the next clutch replacement. If you require another 100+K replace it with a new one.

If you are increasing the HP expect to get fewer miles on a DMF than you would if you had stock power. The same goes for spirited driving and launches they will reduce the life of a DMF.

Keep in mind that a DMF is a wearable item just like brakes and tires so expect to replace it at some point.

The final step for the flywheel is .350" to .345". Do not remove more than .020" from drive surface.

So I guess it can but only a tiny amount.
