Just machined my flywheel. as i'm installing a new clutch.
The actuall friction surface was sitting 0.5mm higher than the surface the pressure plate bolts to, anyway i'm sure that the friction surface would have been machined down a few times, but by the look of things the ouside ring had not, so i was thinkin that maybe the difference in hights used to be greater than 0.5mm, and because it is now less that the pressure plate would not be putting clamping pressure on the disc. Anyway i took a punt and i've made the difference 2.0mm, as long as the clutch still disengages i guess it should be better than ever?

Completely lost me with what your tryiong to get at.

If you sent your flywheel to a reputable business they know what they are doing and keep everything within the manufactures specifications.

I was doing ok up until the 2.0mm difference, where did that measurement come from??

But you would me right, if you were worried you could always have the out side where the bolts go in machined back a little to give the friction face that 0.5mm difference. You will soon know if it will operate when it comes on boost, it slips then the pressure on the clutch isn't enough and that friction pad will need to be higher than the rest of the clutch.

when i took the flywheel off the friction pad was allrready 0.5mm higher than the rest of the flywheel, i figured that this used to be a greater size, 1mm or something, so i have already machined the oustide edge where the bolts go down abit, to make it so the friction pad is now 2mm higher, i was just wondering if anyone knew if 2mm was a good size... as i've just taken a guess with it.

ahh... makes sense now

yeah, good question mate, I have no idea with VL flywheels, but I'd have to say you would have to be ahead of the game and if it's disengaging the clutch then it's working spot on.
