WTB Throwout bearing for '94

[Rusty]

I'm looking for a German-made throwout bearing for my 1994. Any chance anyone knows where I could find one, or has a spare one they may be willing to part with?

I've been in touch with Jim Jandik at Power Torque Systems based on great recommendations from this board, and while he's very helpful with most parts and is also looking around for a thrwout bearing for me, he doesn't have any available right now and the part is proving elusive so far. I've heard bad things about the Chinese-made bearings that are mostly available now... the last thing I want to be doing is replacing the bearing again in a few thousand miles.

Thanks!

Try Jerry's Gaskets for a NOS GM part:

Bushing, Transmission Pilot, 90~95 [8B2]
Bushing, Transmission Pilot: One Transmission Pilot Bushing is required per engine. NOTE: This is a OEM, NOS part made by ACDelco.
$13.75

Kurt White of whiteracingproducts.com had them about 6-7 months ago. However, he would only sell TO bearings as part of a "clutch kit".

I think the OP is about a throwout bearing not a pilot bearing.
However, replacing the pilot bearing when doing the clutch is a good idea.

Thanks for the replies so far from everyone! Last ditch effort here, as my t/o bearing is definitely not working right anymore and I have no choice but to replace it when the rest of my clutch parts go back in (thanks to Jim at Power Torque Systems for being really helpful with those parts and being really great to work with).

Any recommendations for a t/o bearing anywhere? White Racing is the only one I've found ANYWHERE with the original German-made bearings, and he's only selling them with a complete clutch kit. I've checked eBay, Jerry's gaskets, and had our local GM dealer unsuccessfully put out a memo looking for NOS anywhere in North America.

Short of someone being willing to part with one that's in their garage, I'm guessing that I really have no choice but to go with the Chinese-made product? I guess a Chinese-made t/o bearing is better than a broken bearing...

I think I have a slightly used one in my stash of stuff; off Paul Dehnarts car probably has 4K miles on it

[LGAFF]

I have one, but if yours is not bad, I would not replace it

[Rusty]

LGAFF, that's great news. Mine is definitely bad, making a nasty squealing noise even out of the car. I'd love to get the slightly used one you have. How much are you asking and how soon can you get it in the mail? I could do Paypal... please PM me with details (price, payment, etc.)

Rusty, this one does not have the plastic insert but all of Pauls cars were 93 and up.......appears to be in good condition.....any way to confirm the difference? It does appear that this one machined for the insert

What are Original German Made Bearings?
Oops....just seen Jim Jandik Power Torque does not have any ;)
Here is some technical information anyway :cheers:

I have a 91' ZF S6-40 Transmission (Black Label) Parts List No 1052-000-035 with a collar diameter of 1.373 inches and a 94'-95' ZF S6-40 Transmission (Blue Label) Parts List No 1052-000-087 with a collar diameter of 1.305 inches.

a. Here is a source for the 90'-93' ZR1/LT5 Throwout Bearing Power Torque Systems Throwout Bearing (http://www.powertorquesystems.com/Corvette/CorvetteTB.htm) Part #: 23243
b. Here is a source for the 94'-95' ZR1/LT5 Throwout Bearing Power Torque Systems Throwout Bearing (http://www.powertorquesystems.com/Corvette/CorvetteTB.htm) Part #: 23244c. This is exactly what the Throwout Bearing looks like as cited above in both cases as the differences in internal diameter is not noticeable from a picture only.

Thanks, I will check it....seems all of Pauls cars were 94s.....

[Rusty]

LGAFF, I'm reasonably certain that the '94 and '95 t/o bearings had the plastic sleeve. If you're certain that the one you have is missing the sleeve, it sounds like the part probably won't work after all. Please let me know for certain... it seems odd that if the part came off a '94 it wouldn't be the same.

And thanks for the technical information, Dynamite.

[Rusty]

Took a close look at my t/o bearing, and had to look pretty closely to see the teflon sleeve in there. Any chance the sleeve is in the t/o bearing you have LGAFF, and just not obvious? It would be great if this part worked out for me...

I do not see it in there, will measure to see the diameter tonight

1.37, looks like a 91 version

Thanks for checking and getting back to me LGAFF. I guess I'm still on the lookout.
