Best replacement TOB

[smg1138]

Thanks! So I’m trying to understand why this part needs to be replaced too? Is it’s revised part of the same part that’s already in there?


Also, does anyone know if the Exedy kits are coming with the revised TOB now? Trying to decide if I should use what comes in the kit or go to Toyota and get one there just to be sure.

I'm going to post my DM response here so everyone can see it.

No problem, I'll try and explain this as best as I can.

The internal part of the throw-out bearing is plastic. This plastic essentially just glides back and forth across the shaft on the input housing. When the bearing get old, or if there is a clutch fork issue. The bearing will not slide properly on the shaft causing it to bind further degrading the bearing. The shaft itself could be taken out and cleaned however I have had no luck removing all of the worn plastic marring on the shaft when installing a new bearing. If the new bearing isn't installed on a clean shaft then the plastic marring left behind will further degrade and prematurely wear out the new bearing. Since it's a pain to get to it, I look at it as a rather insurance part. It may not need to be changed but I don't think you want to do what the rest of us have done and drop the transmission again or pay a shop to do it the second time.

I just bought one of the Exedy OEM clutch kits from 86speed a couple of weeks ago. I also got the revised OEM throwout bearing from Subaru.

- The OEM bearing had a dot of white paint on the side, the Exedy bearing did not.
- The box for the OEM bearing noted the country of origin as Japan, whereas the Exedy bearing's box was marked made in China.

My conclusion from this was that while I don't know whether or not the Exedy bearing is made to the "revised" specs, they are not coming from the same factory unless the country of origin was mislabeled on one of them. I put the OEM bearing in.

You got the OE replacement clutch kit, not the OEM clutch kit. Misleading, I know.

Exedy (Daiken) is the OE supplier, but their OEM parts =/= OE replacement parts.

You are correct, thanks for the clarification. Exedy calls it the "OEM replacement clutch kit", I guess meaning that it's the replacement for the OEM clutch, not that the kit itself contains the OEM parts.

This is interesting because my OEM TOB died at 59k miles and the one that came in my Exedy kit is just about to die at 55k miles. Why can't anyone just build a TOB for this car that isn't garbage? I'm installing the latest Toyota TOB (white dot) soon. Hopefully this one is better because dropping the tranny every 50k miles to replace a $20 part is ridiculous IMO.

It's not the design, but the size and use case.

I read somewhere that the flex in the OEM fork is the culprit and not the TOB itself.

Is there anyone with uprated Fork and pivot who has had the OEM TOB die prematurely?

[smg1138]

@Thefalls I'd like to know that as well. Just to be safe, I ordered a Verus forged clutch fork, snout, and revised OEM TOB. I'm trying to eliminate every possibility because doing this job is a huge PITA. I still love driving manuals, but dealing this this crap every 50k miles is stupid. I don't care what anyone says, it's an engineering failure.

I did the same, and I'm hoping that it lasts for a lot more than the 53k miles that the original did. Will let you guys know in five years or so how it worked out

Not to hijack a thread. I just installed an Act 6 puk clutch kit in my 2013 FRS. I put in a Versus forged fork, chrome moly pivot, and SKF TOB. It's working fine but I do have a slight squeak sound when the clutch pedal is out. If I put a little pressure on the pedal, it goes away. I've pulled the boot out of the transmission housing to let the fork move more freely and this helped. I don't know if the TOB is actually turning when to pedal is out. The top of the fork is against the housing when the pedal is out. Any ideas?

Well, I ordered the Sachs bearing. At 5 times the price of OEM I hope it's better. Also bought a Verus Arm and Pivot from a member. Now to choose a clutch upgrade suitable for a future Edelbrock S/C.
