Need HELP to identify the correct throwout bearing to use for my 66 Mustang

Post #1 by BobSled » Mon Aug 20, 2018 11:16 pm

Hi!

I'm new to this forum but am hoping you can help. I recently purchased my first car...a 66 Mustang with 200ci engine and T5 transmission (T5 is F2ZR-7003-AA REP-AW). Unfortunately it stopped shifting shortly after I purchased it so now I'm in the middle of a clutch replacement!

I'm a newbie when it comes to repairing vehicles...and the fact that it isn't "stock" seems to have complicated things a bit. I ordered a clutch kit for a 66 Mustang (200ci)...seems like a safe bet, right? Well, the 9" disk and pressure plate that came in the kit look the same as the old ones, but the throwout bearing that came in the kit is quite a bit different than what was in the vehicle. See attached picture.

So my question...will the new throwout bearing (with tabs) work ok with my old clutch release lever and T5 transmission, or do I need to buy one that looks like the old one? If I need to buy a different one (one that looks like the old bearing), will there be any issues using it with my new pressure plate?

Thanks for any info you can provide! Or let me know what additional info you need to help me figure out what I need to do to get my '66 back on the road!

To answer your question would need to see a picture of the throwout bearing arm. Good luck :thumbup: :nod:

Thanks for your quick reply! I took some pictures of the throwout bearing arm (front and back) but I'm unable to attach them to this message (website says "Error. Sorry, the board attachment quota has been reached."). Any idea as to how I get around this?

The lever/arm out of my car has a weld on it (modification?) but it sure looks similar to this one I found on the CJ Pony website!

Looks like someone welded it for sure, maybe it had cracked or they shortened a longer one or something. Anyway, have you tried the new TB on to your arm to see if it fits? Those two little clips go into the concave backs of the ears on the arm and hold the bearing in position. If the two bearing assemblies are roughly the same height when installed, and the new one clips on and looks pretty centered, then I think you are good to use it.

Well, I used the new bearing with the tabs, but after installation it didn't travel smoothly when I depressed the clutch pedal (there was a bit of a shudder as if it was grabbing). So I decided to go back to the old style (new bearing, but old style without the springs tabs) and it moved smoothly and without any noise. I re-installed the drive train and all seemed good...until I noticed a little oil dripping out from beneath the rear seal! Arrggghhh! I was so careful putting in the rear seal and oil pan gasket (including offsetting the rear seal so it wasn't flush with the block)!

I've taken it all apart again and I think I discovered the problem. At this point it's hard to tell where the oil is coming from, but I think it's the fact that I didn't seal the crankshaft bolts. I didn't notice this the first time around, but it looks like they go right through to the oil pan. Is this correct? If so, what kind of thread sealant do you recommend? It's a 1966 with 200ci 6 cylinder engine.

Yes, you do need to seal the flywheel to crankshaft bolts. Almost any sealer will do, as you are just keeping oil from seeping through the threads. Loctite PST (stick) is one that's common at retail shops, and the 545, 565 and several others are fine for this. Likewise, Permatex #2, ARP thread Sealer, or any other thick "non-hardening" sealer is fine. A little goes a long way.

Just be careful not to use Loctite 271 'red' threadlocker. Though it will seal, it will make disassembly a PITA. If you want a locker that seals, I would use the low-strength 'purple' 222. You normally just want a sealer though- not a locker.

Thanks for confirming that I need a sealant, and for recommending so many! :D
