will be installing a fidanza alum. flywheel and blue spring clutch i got from the GREAT Lee Gaff and was wondering what everyone thought.....should i get the flywheel balanced? should i change the pilot bushing and throwout bearing while i'm there? do you believe the pressure plate is good? the car has 40k miles....it's Peter Bernards old ylw 93 Z....by the way if anyone knows how to get in touch w peter please PM me..... brody p.

Definitely change pilot bushing and release bearing (throwout bearing), there'll never be an easier time to get to those items! I suppose one could argue that with 40K, the throwout bearing might still be very serviceable, but given that the trans needs to be pulled to change it, do you really want to tempt ol' man Murphy?

As for the pressure plate, if the clutch previously was holding well, I suppose you could reuse it as long as the friction surface looks good. I know that the fingers of the diaphragm spring are rated for a certain number of cycles, and at 40K I am sure there's lots of life left in it. I'd probably still replace it, but I have gotten tired of doing the same job twice.

I concur with Andrew on the bearing and the bushing. I would replace the friction ring as well since it is used.

Marc Haibeck advised me if there is nothing suspect on the throw out to not change it...rare part

good price from Mr. White...might be worth it...

I would attend to the rear seal also while you are in there.

Good advice BTW. Something I need to get to once I pull Dana 44 for gears.

Brody,

The usual trick for the pilot bushing has been to pump grease behind it and have it pop out. However, I think I heard that was a no-no with the
LT-5. I have a small puller where 2 jaws get in there and then draw the bushing out. Also told the brass bearing should be used. The roller bearing
breaks down.

Also, no need to balance the Fidanza. They're pretty good from the manufacturer. I've had 2 of them and Marc H says he install them with no balancing necessary. JUst make sure you are using the coorrect ARP bolts.

Here's a simple tool I made from bolts to help align the trans during install to avoid ever letting the weight of the trans rest on the clutch disk which can warp the disc. Just screw them into the bellhousing, a couple in the top holes and another on the side or bottom, just enough to have full thread engagement in the bellhousing. Slide the trans in & install one bolt just snug to hold it in place then use your fingers to remove the alignment studs.
