Had to pull the gear box in my truck to fix a leak... the clutch was one of MANY things I have been inspecting... what are your thoughts on its current condition?

2 thoughts:
- some of the rivets seem to show wear marks, so not much pad left
- you already have it out, may as well put a new one in now instead of later...

Personally it's out already. If you are questioning it, change it and not have to pull it again in a year or two when it is really bad.

I think I spent around $220 for a brand new clutch kit and a flywheel and the original factory parts lasted 10 years, I'd replace it and have the satisfaction of knowing that I won't have to worry about it for a good long while.

This is from a 3/4 ton diesel so nothing is coming cheap here... hmmm. The pressure plate and flywheel are in very good looking condition, the machine marks still look just as good on the contact surface as they do on the non-contact... I wonder if I could get away with just having them turned?

Do they sell just clutch discs? Kits typically appear to consist of pressure plate, clutch disc, pilot+throwout with an optional flywheel. I was planning on replacing the pilot and throwout initially... now it looks as if I should replace the disc... perhaps I should just spring for the pressure plate as well... when the flywheel gets thrown into the mix is when the price goes way up...

Mine was a 93 Ford Ranger and I could not find a parts place to sell me a disc only. Mine the kit was $140, the flywheel was around $85.

There appears to be sufficient wear left on the friction material to go for quite a while yet, depending on your driving style.
What does the friction surface of the pressure plate look like?
How about the surface of the flywheel? Any hot spots? Is it smooth?
the flywheel can be re-surfaced, there is no need to replace it unless it is REALLY bad.
However, as others have said, you have it out now, you might as well go ahead and install a new (or rebuilt) disc and pressure plate. If you have the option, get the heavy duty unit. By the same token, replace the release bearing and the pilot bushing/bearing now that you are in there.
Be sure to tighten and torque the pressure pplate bolts properly!

It depends on what you do and don't like to do.

Depending on your driving style, you can probably get a lot more miles out of this disk. And if you don't mind pulling the tranny again when it actually does need to be replaced, why not get another year or two out of it?

On the other hand, if you paid a shop to remove the tranny, I'd have probably have a new disk put in. That way you're only paying to have the tranny removed one time.

Pretty much what Omaha said, although, I will note that the work to put in a new clutch disc is no more than putting the worn part back in.

Me, I'm a lazy sort and don't like to re-do a job I have done recently, unless money was uber-tight, I'd spring for at least a new friction disc while you are doing the pilot and throwout bearings.

I have put in clutches without turning the flywheel or the pressure plate and got away with it.

Offhand I don't see any reason the flywheel should be damaged, I would think turning it is all that's needed, if that is needed at all.

Frequently with HD Diesel stuff, the OEM part is all you can find, you might check NAPA or similar for an extra-thick friction disc, and/or something equivalent to the OEM part for a little better price.
