Flywheel and Clutch question?

frank.herbst_old · January 23, 2011 at 1:07 PM

We have our HiPo engine at the shop for rebuild. They have asked me to bring over the clutch I want to use for part of the overall fit and balancing process.

My flywheel is original and doesn’t look like it is very thick to me. The area where the clutch disk would mate up to is only about 1/8 of an inch thicker than the starter gear ring. Does this sound OK? Does anyone know what the thickness of the flywheel should be?

Also what type of clutch do you guy’s recommend for a car that will get driven but not raced.

Centerforce I is plenty of clutch for a Hi-Po.

this is from the 1966 Ford shop manual: ..."If it is necessary to remove more than 0.045 inch of stock from the original thickness, replace the fly- wheel........"

I don't know the original thickness

I'm using a Ram 10.5in. clutch and pressure plate in my car and very happy with it. I think when measuring the thicknees of the flywheel you should go to the outter edge where their is no wear take readings and then measure the center section. This will normally show the difference in wear. (0.045)

I agree, don't think I'll ever use anything else.

Measure the thickness of the flywheel edge. It should be .85" when new. You can cut up to .045", so minimum thickness should be .805". The ring gear is .14" below the clutch surface, so even at max wear there sould be .095" clearance.
