I had a bad bearing noise and all the past threads told me (along with bauley) that it was the input shaft bearing.
Noise came when the clutch was not pressed, in gear driving and just sitting at idle, and stopped when the clutch was pressed in.

I replaced the input shaft bearing and oil seal, clutch, pressure plate, resurfaced the flywheel, changed the pilot and throwout/release bearings too.

After ALL the work I did with this thing (my first tranny job) the sound is STILL there only quite a bit worse

What else could it be?

anyone...

son of a bitch...

up for some REAL tech..............

I know you replaced the pressure plate but did you remove the bolts in crisscross patttern in several steps? Sounds like the plate could be warped. That is what will happen when you don't during the removal and install.

pdiggitydogg

I did that...but it was making this sound before I touched anything. I took it all apart because I was told it was input shaft bearing

Sounds like tranny bearings to me... the ones around the shafts, on the casing of the tranny.

pdiggitydogg

Which would have been the input shaft bearing.
Could it have been the countershaft bearing? (I swear if thats it I'll go berserk)

Lord Helmet

There's only three things I can think of that would cause the problem which you said you replaced already:

1. pressure plate warped
2. input shaft bearing
3. clutch release bearing

Ever thought about taking it to a trusted shop for a second opinion?

pdiggitydogg

Sadly, all the shops around here are shady...but, yes.
The only reason I would is because its such a giant pain in the *** to remove and install the tranny.

does it go away if you lightly touch your clutch with your foot?
it really sounds like the release bearing to me..
did you put lube on it b4 you installed the new one? did you use and oem release bearing? the ones that come with aftermarket clutch kits are made of a hard plastic and metal and are infamous for squeaking..

also you may have to readjust the clutch petal. doing this can take some of the pressure off of that bearing and stop the squeak. just don't go too crazy

pdiggitydogg

Goes away when fully pressed.
Release is an exedy piece, which is oem as far as I know.
Yes it was lubed well.

Pedal has nothing to do with it.
Remember, it was doing this BEFORE I touched anything.

I had the same issue as you did, replaced the input shaft bearing, clutch, pressure plate, throwout bearing/pilot bearing, noise was still there. There were other bearings though inside the tranny that I didn't replace that still could have been the culprit. There is another mainshaft bearing opposite of the input shaft bearing, and then there are 2 counter shaft bearings. There are also needle bearings on the shaft(s) of the transmissions.

If you look at this thread, he has replaced every bearing in the tranny, checked all clearances, and still has issues.

I came to the conclusion that I didn't want to pull the tranny apart, and I wasn't skilled enough to check all the clearances, play with the shims, and deal with removing the other bearings and having them press fit back on. Not to mention cost for doing all that would be about as much if not more than another tranny for my d-series. Plus there was the downtime.

I understand your frustration, trust me. It's a damn bitch to pull that tranny, do all that work on it, just to realize when you put it back in, that you feel like you fixed nothing. Did you happen to look at the other bearings when you had the tranny open? I had read previously that checking the bearings by spinning them was a good indication to tell how messed up they were, then was told that that's not always a good indication.

When my 99 D16Y7 tranny took a dive, and everyone told me it was the ISB - well, it was the ISB along with the bearing at the opposite end of the same shaft.

That bearing was majorly destroyed - chips were missing off of the actual ball bearings. It made my car sound like it was going to grenade itself....

BauleyCivic

As I said in your PM, its probably one of the other bearings on the mainshaft. My friend had this problem with his 00 Integra, and it ended up being one of the bearings at the opposite end of the mainshaft. Spin ALL bearings and check for clicking/unusual noise.

pdiggitydogg

I did mess with the gears along the mainshaft (well I played with the gears) and didnt hear any specific sounds.

I broke down and took it in. I needed some other bs crap done to it as well, since I failed on some other work.
For those that want to know what it is (if found), I'll post it up here.

dayum, thats sux man...

I just pulled my YS1 and cracked it open because I'm experiencing the same problem you have. A rattling noise when I'm in gear and sound goes away with the clutch in.. I have the main shaft and counter shafts out.

The input main shaft bearing looks good and seems to spin quietly. The counter shaft bearing in the clutch housing however seems kinda loose with the counter shaft pulled out. Is this normal? I think when I put the counter shaft back in place those bearing would be snug, right?

How do you pull out the main shaft bearing? and the counter bearing?

I think I'll repalce the bearing s since I'm alreay in there...

Stoich EG2

at least i don't think you are going through what im going through... i've been through about half you steps... took my tranny out 3 times already and even got a new tranny.... i have spun bearings ... aka crankwalk? basically, i can pull and push my flywheel in and out about 1-2 mm and it moves my pulley's on the timing belt side
