sorry for all these amature questions.....but why do flywheels need to be resurfaced when u install a new clutch? and do they really need to be resurfaced?

 

I'm thinking it just incase there's any score marks or scratches, so it doesn't damage the new clutch plate plus I think it's so the surface on the flywheel isn't to smooth and the clutch start's to slip. Not to sure on the last bit.

 

Actually you should. The black & blued marks that are on the surface is really raised and will take some life out of the clutch disc. most manufacturers will not warranty the clutch in the event of a failure unless it has been done. Use a machine shop that will grind with a stone the flywheel, not a lathe type (the lathe has a hard time removing the rough spots due to the hardness).

Also by not having the flywheel ground, you shorten the life expectancy by quite a bit depending on the surface condition.
