There are several different length collars and the release bearing rides on the collar. Different collar heights require different pressure plates, so you just have to match the set. Somewhere on this site there is a chart that shows all of the collars and what they go to. I just can't find it.

Hey, thanks a lot for all the tips you guys.

The clutch and pressure plate are sold together as a kit so I should be good to go in that department.

What is the collar you are talking about? Is it part of the release bearing? do I reuse the old one? What's the story?

The bearing is a press fit onto the collar. You need to remove the old bearing and install the new one.

Here's a link to that picture that Jeff G might have been referring to. You can see the bearing on the bottom and the collar on the top, with the important measurements.

Thanks Zed. That's the one I was trying to find.

Now I'm getting paranoid. As far as I can tell the transmission is a Type FS5C71A if that means anything.

Chances are good that the collar stayed with the trans when they did the swap, but it's possible that they reused the old clutch setup from the 240 and transferred the collar to the new trans. Just measure the collar height before you order your clutch kit.

If you guess and get it wrong, you'll have to pull it all apart and find the right collar to fix it. Another option if you are in a hurry is to order both clutch kits and return the one you don't need.

Should be the 71B, not C, according to the attached from the FSM. European, correct? Factory stock 240Z? Is it working now? If so, there should be no major problems. You're changing the clutch, nt the transmission.

Just make sure to measure before installing. Where people go wrong is when they change the relationship of the throwout collar ears to the slave cylinder position, accidentally, by trying to match a combination of aftermarket parts to the year of their car. Measure before installing. The various web pages, like the one I linked above, are just starting points to help find the right parts, to get started on a swap.

I'm probably over-thinking the situation and worrying about a problem that probably won't exist. I'll stack all the old parts on a piece of glass and stack the new ones next to it and compare measurements before installing.

Considering the agony of trying to diagnose a problem after everything's installed, you can't really over-think it. I got lucky on my first clutch maintenance because my car was factory stock and the clutch kit came with its own collar and bearing. Since then I've read the painful stories and collected a variety of used pressure plates and collars, so I can see where you can go wrong. I will always measure first in the future.

Hi you guys,

I figured I'd give you the update/outcome of my clutch repair. I ordered the Exedy kit from RockAuto that was listed for 1972 240Z. This was Exedy part number 60029. I think someone had mentioned part #60009 so I was a little afraid that I might have the wrong part.

Well, 60029 was the correct kit. It matched up perfectly with what came out. No collar was included with the kit.

My only "problem" was that the release bearing was damaged (new in the box) I called Rock Auto and they credited me the cost of a new bearing purchased locally and I didn't have to go through any rigmarole about sending the defective part back or anything like that.

Man, what a difference. You can tell that the previous clutch was worn out and slipping even before it became obvious. The new clutch grabs so tight now I have to rev a little higher than I used to in order to keep from stalling on takeoff.

I've gotta be more careful now because it's a ticket waiting to happen.
