Identify clutch, pressure plate and flywheel
 
20 Attachment(s)
So I am parting out a 95 and keeping what will be useful on my 91 which is getting an old Greddy kit. I need to identify this clutch setup and figure out if it's worth using (otherwise it will be sold, which I also need the info for). Any help/idea are appreciated.

Here are some photos:

Apparently I forgot to take a full shot of the friction side of the flywheel. I can if that is important, but hopefully the marks will be enough.

looks like the clutch is shot. The Fidanza flywheel needs a new plate, but only if the pilot bearing area will still hold a pilot bearing.

Yeah, the clutch disc is reasonably worn. I haven't measured it though since I don't know what the thickness should be. I assumed I would probably be replacing that (and I prefer full face anyway).

I assumed on getting a replacement face for the flywheel since it has some heat scoring. Good to know it's a Fidanza. I thought it looked like one and the F at the beginning of it's code seemed to indicate that. Are they all the same or do you know the specific model? If not I'm sure Fidanza can identify it....

What do you mean hold a pilot bearing? Does the hole wear out or.... I have only done a few clutches over the years (DSM, WRX, Civic) and always on stock flywheels. I may have some gaps in my knowledge.

Any idea about the pressure plate?

pressure plate look too worn. On Fidanza flywheels to diameter that holds the pilot bearing seems to loosen and the bearing can fall out. With the part number, Fidanza should be able to identify which plate to use.

Thanks, so I suppose I should scrap these and only reuse the flywheel with a new friction surface.

Is the friction surface the part that looks too worn to use on the pressure plate? The fingers seem straight to me and the grooves from the throw out bearing are minimal.

yes
