I would beg to differ. As a shop boy in a machine shop, I got the dirty job of re-surfacing flywheels. Even ones which didn't show any signs of warpage or damage still had lots of hard spots in the mating surface due to people driving while slipping the clutch, worn pressure plates, etc. The hard spots tend to "glaze" more and will affect the way the clutch disc slips on the flywheel. You can also hear the hard spots go by in the lathe, as they make little "thunking" noises as they hit the cutting tool. I never took off much of the surface. Just enough to get the hard spots out (like 1/16" or so). I do all my flywheels, because after all, when's the next time you're going to be able to get at it? Besides, whack a half inch off the flywheel and you get better acceleration right? *smirk* YMMV Keith Adams Calgary, AB, CA 86 Westy "Roxy" / 87 Syncro project "Hugh" |
