1986 v6 4speed 3.4 swap, I need to know which way the throwout bearing goes on the clutch fork. I can not find pics or a video of the 4 speed and its been a month since I took the old one out. Thanks!

This should help a little bit:




fast-forward to 6:49, and you can watch her install the clutch kit and the throwout bearing.

Basically... the "bearing side" should face OUT and away from the transmission, towards the clutch kit. The two little arms rest on the pads, and then force the throw-out bearing INTO the clutch disc... if that makes sense. Basically... if the bearing side is facing the transmission, then you're installing it wrong, because nothing inside the transmission side of the bell-housing is spinning... and the throw-out bearing rests on the non-moving shaft. It's the clutch disc that's spinning.

Thank you. I was 90% sure that was how it went on but better safe than sorry, too much of a PITA to not do right the first time.

Yes... and really important... make sure you properly grease the shaft that the bearing will be sliding up and down on. It must be high temperature grease (the clutch kit should come with it). If you don't, you'll quickly wear through the ... **** , whatever it's called. The tube if you will that the input shaft spins from... the tube that the bearing slides up and down on. You don't necessarily need to grease the splines that the clutch disc slides up and down on, as the clutch material ends up "lubricating" it as well anyway... and the grease on the splines ends up getting caked anyway... but you can if you feel comfortable doing so...

be nice its an honest question and they learned something like lubing the sleeve and checking that its seated correctly. if you've never questioned doing something for the first time on a new to you car are you really wrenching properly?

Well now I am going to make things worse.

I say to NOT put grease on the input shaft of the transmission where the release bearing rides.

read 82ta's post about it seen above. ive seen and had to deal with the aftermath of not lubing that area at least a little. when you pound that stupid sleeve out of a getrag for 5 hours while cracking it into tiny pieces because its paper thin and locktighted in let me know. a skim coat of high temp wheel bearing grease is not gonna hurt the clutch unless you get that bearing real hot or submerge the fiero either way your doing something wrong if its above 400 degrees

I was hesitant as well, but the clutch kit came with grease, and I did a ton of research (because there were no instructions). I saw tons of articles talking about failure because they didn't use grease on the shaft that the bearing rides. It can start to bind pretty quickly, and starts wearing away at the sleeve. Without grease, it also won't properly return to the fully disengaged position, which creates a wear spot in the middle, and can lead to rattling at idle, etc. It seemed to be unanimous to put grease on there. The only place where people were 50/50 on, was on the actual input shaft itself that the clutch disc rides on. That's because people said that if you use too much, it can eventually fly off and get on the pressure plate.

I had my daughter put it on the sleeve, but very, very little on the splines... basically whatever residue was left on her finger after she did the sleeve (which was basically nothing). The internet people said eventually the clutch dust will lubricate the spline (in a sort of way)... but you definitely want to lubricate the sleeve.

I greased the sleeve, shift fork bushings, and shift fork attachment points. They need at least a skim coat just so they don't rust/bind up(but not enough to fly off and contaminate the flywheel).

Funny, I wish you knew the history of the person you are talking to. He's provided probably 80% of the knowledge base on this forum and it's all documented. And Buddy probably won't even reply to your post. He'll let you dig your own grave.

I'm glad the OP got their answer but seriously guys stop acting like children!

-Carter, take some feedback, digest it, and keep your mouth shut. Being disrespectful when a dissenting opinion from a very skilled member of the forum disagrees with you is a great way to end up unpopular, when its quite easy to look at your post history and learn you aren't quite an expert yet either, nobody knows everything, nobody is the last word on anything. We could have had a very interesting discussion on the benefits and drawbacks of lubing the input shaft, because I have heard it both ways, but you shut down any chance of Buddy explaining his view point when you post about beating out the collar on a Getrag basically said "you're stupid and wrong because of my anecdotal story"

-IMSAGT, I have a lot of respect for you and your work, but seriously what benefit is insulting Carters character, and calling names going to bring to the table. He was in the wrong here, but that attitude make this forum feel like every other crappy car forum filled with bitter people on the internet. Just let it go next time dude.
