Clutch component purchase... - ZR-1 Net Registry Forums

Roadster · 02-28-2017

After making a purchase a few months ago, I finally unpacked it today....
This was off a ZR-1 with 40K miles. There are lots of pics when unpacked and after a quick cleanup of the parts. I am no clutch expert by any means, so those in the know feel free to comment on the condition of these parts.
Also the DMF has slight movement from side to side. I would imagine that this is good??? Meaning that the flywheel springs are still good???

Packed very well from the shipper...

clutch disc looks good to me...

Pressure Plate....

Also included was the clutch fork...

Clutch disc certainly looks useable but that clutch...hope you didn't pay much for it because it's been run pretty hard as has the flywheel.

You put that stuff in your car and it's may chatter.

There are a few...very few...machine shops which can machine a DM flywheel. If you can find one, I'd have it done. Then I'd buy a new clutch.

If I am going through the hassle of removing and reinstalling a trans, fw, etc, no way am I installing a used clutch disk. I agree w Hib, dump the weight and go w a low mass FW.
There are ways of mitigating the rattle.

Appreciate all of the remarks.....Jim @ Power Torque was the person I spoke to before I made the purchase mentioned. I also had him rebuild my clutch MC and purchased a stock slave from him a few years ago. I also new that I was taking a chance making this purchase. He did mentioned that they can cut the DM (as Craig said)and have cut some already. Tried contacting him yesterday, but he may be out on the race circuit this week.
As mentioned I do have a NOS PP and clutch disc that was sitting on the self since 2004 from another purchase. And yes there is the possibility that the disc in the pics above with this purchase may have been added, as the disc looks pretty good.
Just putting away parts for the future, making easier for when the grandsons inherit the Vettes.

I rather stay stock, but then that may be just me. I read to many stories when some owners have been unhappy with going to low mass FW. Again I don't have any noise from my trans and just don't want to take the chance changing to something different down the road. And this is something I don't need to change soon, who knows my current setup may well last for a long time.

So right now I have 3 PP's, one in the Z, a NOS unit and the one shown in the pics. Also have 3 clutch discs, the same as just mentioned. And now have 2 DMF's, which both can be cut and hopefully reused once again when or if ever needed.

Cost, yes cost....for what I spent on the two separate purchases between the new NOS and used original pieces, it was still less than purchasing a NOS DMF, if you can find any. Or less or close to buying a used DMF in good condition, again if you can find one. And if Jim can cut the PP & DM shown and still be in specs, then I would say I did good

. If not

, then I still have the NOS pieces and some expensive wall or table art.......lol

I thought about going with the LW flywheel when I had mine apart. What kept me from it was remembering when I was at Marc's and he started one up to move it - I about freaked because it sounded like it had a rod fixin to come out the bottom. He said no that was the aluminum flywheel. I'm not driving something that sounds like the engine could ventilate at any moment...

Another vote for the Al FW, and bumping the idle. Like Hib and Dom said, the accelleration - especially in the lower gears...is well worth the sometes rattle.
