Hey folks,

My buddy just finished a clutch job on his civic hb, and he forgot to put the exedy release bearing grease on the bearing, and right now its making quite a bit of noise til you clutch in.

Is this bad? How can he fix it without dropping the tranny again?

The release bearing would only make noise when it is engaged with the clutch pedal down. Is that when you hear the noise?

H22_CB7_JAY

No.. We hear it until we clutch down.. Clutch down even the slightest bit and it goes away almost instantly..?

H22_CB7_JAY

Kinda getting scared for him now!!

H22_CB7_JAY

It sounds like a metal on metal rubbing together almost.

If the noise is when your foot is OFF the clutch pedal, it's probably the input shaft bearing.

H22_CB7_JAY

Crap. How does he fix that? He's gotta drop the tranny?

H22_CB7_JAY

Also, hes saying he thought he replaced everything in the tranny that would've been bad, as far as bearings go. Does he just need to grease it and it'll stop making noise or what? And is this part in the tranny where the fork connects to?

jbpnoman

No, and no. It's the last bearing you can possibly remove from the transmission when overhauling it. It's inside the bell housing, and involves full disassembly to replace. That isn't the kind of thing you "think" you've replaced. You either know you did, or you didn't.

H22_CB7_JAY

Ok, he hasn't replaced the Input Shaft bearing. Just what came in the clutch kit, and for bearings it was just Release Bearing it came with.

Question is, how can he fix this? Or he can't without dropping the tranny and replacing the bearing? Will it get worse?

jbpnoman

It will get worse. Transmission overhauls aren't exactly easy. Your friend should pick up an FSM and start reading up on what's required, or just drop the transmission off at a shop and have them do it.

H22_CB7_JAY

LOL I appreciate your suggestion, so does he.. But he did it to learn, and just had to the hard way.. He'll fix it, and get it right your sarcasem isn't needed, and a bare boned answer was all I expected.

Thanks for the info have a good one.

jbpnoman

Uh, where was I being sarcastic?

H22_CB7_JAY

I apologize for taking your post for sarcasm. And, he read up as much as he could before jumping into all this. I feel bad for him and was hoping I could deliver some good news.

Check the FAQ sticky for a link to a DIY on replacing the input shaft bearing, it's what I used (and the Helms manual) and I made out fine. I would suggest snapping photos as you go when taking it apart, and follow the Helms manual carefully. Watch out for how the shift finger of the interlock fits into the shift forks before taking out the main and countershaft assemblies. You basically want the forks in neutral when putting it back together. Just take close up photos and study the diagrams too. He will want the oil seal that goes with the ISB also. Read through the entire disassembly and reassembly before starting.

Other than fresh bearings and seals, your friend will need basic hand tools, as well as feeler gauges. While he's in there, it would be smart to replace the synchros, which will require a small press. People do it without a press, but the correct (and smart) way to do it is with a press.

H22_CB7_JAY

Thank you very much for your info, I will pass this on. I did however hear from him that he had no interest in changing this anytime soon.

What kind of damage can be done by leaving it to get worse? How long roughly? Please and thanks.

I'll inform him of the press part, feeler gauges, and replacing the Syncros. Thanks alot.

Mine growled for a long time without seizing or blowing up, but his mileage may vary (literally). No one can say.

As far as damage, it could come apart and get pieces everywhere. It could seize and cause more damage. However, I got lucky, perhaps others can answer this better.
