I was looking at the flywheel on my 170g and it is worn severely. I know that the depth of the surfaces is supposed to be 1.437" and i'm sure this will be greater than that after it is resurfaced. My question is the outer edge cut down so that the surfaces are back to the original specs? and how does this affect the clutch adjustment?

A good clutch shop or machine shop that's done flywheels before should know how to do this. You cut the lip where the pressure plate bolts down the same amount you take off the clutch surface of the flywheel. Normal operating procedure for flywheels. If it's not warped and hasn't been resurfaced a billion times, it should be good for resurfacing. Check the yellow pages or ask around the truck repair shops to find a good clutch shop. Way less money and if you ask around for a good shop, definitely better materials than you can get in the aftermarket and OEM kits. Also, they can tweak the set up slightly to better suit your situation if it needs to be.

I should have said, you may want to take a copy of the depth spec (1.437 inches) with you in case the flywheel is really worn down so the flywheel can be machined back to spec. Also, if done correctly, there will be no effect in clutch adjustment, you'll just have to adjust it back out.

It had a button clutch in it. I thought the button was a heavy duty clutch?
