Default Correct throwout bearing for M46?

I need to replace the throwout bearing for the M46 I am swapping into my 91 245 auto.

I see the Sachs SN3727 from FCP Euro. Is the the correct part. It looks a little different from the bearing I pulled off.

Here is the set up on the M46 I purchased a new fork, but it matches what is pictured here.

Thanks for your help

Throw out bearings are different for Sachs and Borg & Beck clutches. The bearing pictured is for a Borg & Beck clutch.

You need the one that the bearing slides onto the locating pins in the release arm. https://www.fcpeuro.com/products/vol...40-760-3549881

That is correct one in the picture.

I have this Luk clutch and pressure plate. They are in like new condition and I figured I would use them.



I understand these are similar/the same as the Sachs clutch.

That seems to be the same one in my FCP cart, inching closer to putting the new transmission up....

I learned that the hard way. The clutch just refused to work correctly until I figured out there were two versions.

I do not believe my previous message was clear. Can anyone confirm that the Sachs style throw out bearing will work with the Luk clutch?

Buy both, they are cheap. The one I ended up with also fit a Mustang of some sort. Been too long since I did it to remember. I actually had to cut the old one out, it was so beat up and missing bearings.

Use the 6202 RS bearing for the pilot bearing. Yes, the Sachs release bearing works with the LUK pressure plate. That is what I have in my 93 wagon.

Depending on the combination of the mismatched clutch and throwout bearings the clutch would either not disengage all the way when the pedal was pressed or it would slip all the time. I wasn't able to adjust the clutch arm and slave cylinder to make it work right. Then I figured out I had the wrong throwout bearing for the clutch I was using.
