Well here are my results of 15mins of my time after work. I took it to a machine shop to be resurfaced. The stock one was alittle bit warped, but nothing bad that wasnt trued out. After all was said and done, he said it was between .004 -.005 of an inch. He had a hell of a time getting the dowel pins outta the flywheel so he could resurface it, when he put them back in he barely tapped em in with a mini sledge hammer. Is there a certain depth that the dowel pins needed to be pushed back in, or does it really matter and just kinda help keep the clutch and stuff in place?? Here is what it now looks like :

 

Wow, that's nice! Looks brand new.

 

yup, that is until you flip it over.

 

Bump for the question about the dowel pins after resurfacing.

 

The dowel pins just have to be in to a depth equal to just over the pin diameter (it will shear at that point which means it has maximum holding power). Your wheel looks great.. no signs of it ever having beenover heated and the grinding job left just the right finish to mate with your new disk. If it only took .005 to get it there you will probably not have any problems with warpage from it being too thin.

 

Is this out yet? In another thread, Dirk from ACT said they were still a few months away.

I don't need one right now, but just in case I need one soon...

Thanks,

Thanks man.

 

 

Looks good man The dowels are always a pain in the *** to remove as per the machine shop. Usually what they have to do is heat it with a torch and pull them with a pair of vise-grips, not exactly good for the dowels since the heat weakens them and the vise-grips cut them up. They end up shoving the cut up part of the dowel into the flywheel so that you could never tell. Since I do so many clutches I actually bought a Snap-On dowel remover ($250) that pulls the dowels perfectly and easily.

As for the flywheels being balanced, they all have different holes cut into them. Its a way of balancing them from the factory. The flywheel will only bolt up to the crank in one way. There is a small dimple in between one of the holes on the flywheel , this dimple lines up with a dimple in the crank.

 

Gil, what is your opinion on them putting them in? Should I tap them in alittle more?

Actually the pulled the pins out with a slide hammer and some type of thing that slid over top of the pins. No heating required. He banged up and down on the slide hammer and they eventually popped out. I got to stand there right beside the guy and watch the whole process.
