a few other pictures of a calibra, with a DIY job :
****!!!!!!
Holy sh!t!!!!
That's scary!
when you say a d.i.y job whats been done?? looks standard to me from the pics? ive had my flywheel skimmed , wasnt done d.i.y it was done on a lath so hopefully be alright
When they have been skimmed to fukkery on a lathe.
Then not balanced.Everything that goes round ie wheels propshafts flywheels etc needs balancing to stop vibrations.
Vibrations can undo hobos re used bolts with no locktite.
Boom boom boom is the result
or even if its been balanced, it might have been skimmed to the point that the thermal mass isnt enough and when using the clutch the flywheel gets hot and cracks
Yes that aswell.
Its a stupid thing to do.
A light skim wont harm but iv seen somebody showing carrier bags of swarf off to people thinking its funny.
Now he drilled holes in to balance it too.
I saw a rover sd1 fall out with its flywheel on the stebbe straight at Mallory somewhere in the mid 80's.... it luckily went down not up, but the whole car jumped in the air when it did, leaving a pile of shrapnel.
its well known that a lightened flywheel is worth thousands of php(pub horsepower), so prats keep doing it.
another version of the flywheel skim I've seen done badly is in the agricultural world, where they mostly use sintered plates, and the flywheel gets a load of stick.. the flywheels need skimming when the clutch is replaced, but they only have about 3 skims in them. to skim one properly entails having the wear & mounting surfaces machined down the same amount, then the clutch gets adjusted out so it works fine.. people either don't skim the mounting surface and adjust the clutch, so the thrust bearing falls off the end of the snout, wrecking the clutch, or they over skim it, so the clutch plate rubs on the flywheel bolts wearing them away with fairly terminal results...
