clutch/gearbox noise... a question not a problem :)

[CRXDEL501]

hey all,

my question is, i changed the input shaft bearing, and supposedly my mechanic said there was two, like a top and bottom bearing in the gearbox.. but i know only one input shaft..

they were changed because there was a noise when the clutch was out. before changing the bearings, it was alot louder, now a day later, there is still a slight noise, and you can hear it when the clutch is out still in neutral and when you change gears you can kind of hear it go into gear like a click or a clunk. nothing loud, but am i being paranoid?

is it normal to hear some slight noise when the clutch is engaged to disengaged?

Hey dude,

I have the same issue that I posted on thread http://www.ozhonda.com/forum/showthread.php?t=129866

For some reason the noise just goes away when the clutch is in.. =S

I have yet to find out what may be the issue..

[CRXDEL501]

Everyone will say input shaft bearing like I said... I just dont know if that's it since mine has been changed. Am I paranoid ? I don't know. It's louder when air con or windows are going up or down when more power is surging through

[Nonobui]

I got the same problem for mine. asked machanic that being suggested to change the whole gearbox which bost too much. LOL! but being told its still can be drive. so... let it be untill i got the money to.

[twing]

If the noise goes away when you clutch in, it's input shaft bearing.
If the noise comes when you clutch in, it's throw out bearing.

[Nonobui]

thanks a lot!!!

[Nonobui]

so reckon changing the whole gearbox or just do the bearing?

[twing]

Personally I would change the bearing only. The problem with 2nd hand gearbox is the unknown history. It may or may not fail again. Since it's a labour intensive job, I rather do it right.
you can wait until you need new clutch, so that everything can be done in one go.

[CRXDEL501]

if you read what i said, i changed the clutch bearing and input shaft..

noise is still there

we need to look into this problem more as there are so many threadson it.

[Nonobui]

twing: thanks for ur suggestion. Appreciate them.

Any suggestions for CRXDEL501? As said hes changed his input shaft bearing and still the noise is there.

that's okay DLO01 :)
suggestions would be good indeed. Most people you ask do say input shaft bearing but obviously not the issue.

Could it be oil?

Driveshafts are fine.

Synchro are fine

new clutch and new flywheel. I do know my rear engine mount is noisy but don't think this would have anything to do with noise when the clutch is out.

Did you let your ISB wear in? If you did how many kms?

If you didn't, that might be your problem.

[CRXDEL501]

Never knew I had to. How do you wear it in lol. Mechanic never said anything

[thegame888]

Depends how noisy it is. If it gets worse, then yeah, get a new bearing.

I'm guessing you've got a DC2R. They're notorious for being noisy and making a grinding whir from the ISB. Don't know if DC5R's are the same.

Mechanics are always going to recommend changing them. But even if you change it, it's likely the noise will still be pissing you off, except more so because you will be down a shitload of $$$$$.

If its not too loud, get over it and keep driving.

[drifta1600]

yer sounds like i cud bethe input shaft bearing, but it could be that the prongs have worna bit on you pressure plate and the through bearng is touching it slightly and making a noise. dose it shutter at all when riding the clutch on take off?

[FallenAngel]

Never knew I had to. How do you wear it in lol. Mechanic never said anything

Just driving normally will wear it in. I drove around 1000kms before i hit vtec although i think that was abit excessive...

[CRXDEL501]

Well I wasn't told to wear it in... How will the noise annoy you if you change it? I did and can still hear it

[thegame888]

Yep, it's normal.

[CRXDEL501]

how do you wear it in? just no vtec?
noise is back, so cut...

wanted it ready for my turbo set up. how long generally until other things screw up?

[FallenAngel]

by driving normally, hence no vtec or hard accel you wear things in.

I've just found out that there are two bearing regarding the Input shaft bearing.

I'm getting the sound again and i've brought it back to my mech and found out that the top bearing wasn't changed so i'm getting that done today/tomorrow.

might be the same problem with you crxdel501

[CRXDEL501]

quite possibly.
going to have to wait till i have the money to get it done again.
was a complete waste.

[twing]

how much do they charge nowadays for replacing ISB?

[FallenAngel]

Roughly 200odd for a home job
And anywhere from 500+ for workshop.

Ask AK Motors since ur in melbourne if you want it done

If the noise goes away when you clutch in, it's input shaft bearing.

Great info link :thumbsup:

Dam! looks like my input shaft bearing dodgy :(

Box has done less than 5000km since rebuild and LSD install :thumbdwn:

I thought i was just dirt getting in there coze I've got a big hole in the rubber boot cover

I assume you mean the CV with the boot cover? You should get that changed regardless. Any dirt isn't good for anything in the tranny.

What did you get done to the gearbox when you rebuilt it? I assume its not a dc2r box since you got a LSD installed.

Got a new boot waiting at Honda now :)

Thing is the noise stops with just the weight of my foot and no pressure on the peddle

Box is a hybrid B16/B18 F-Factory LSD

bearing were new though

[trentd]

why do honda gearboxes and parts have to be so dear!

[dvsx]

sorry to hi-jack but my dc2 vti-r makes a pretty loud squealing noise only when riding the clutch. would that be clutch or g/box related?

its probly obvious its the clutch but i just want to make sure before my mechanic changes my clutch

[Lukezen27]

Hahhny did so Adrian reused them

[Lukezen27]

I re-greased the release bearing and release fork today via the slave cylinder boot...

Sounds gone thus far :)

Early days yet though

Thrust bearing?

[Lukezen27]

Thrust bearing?

Release bearing

The bearing connected to the release fork that slides back and forth as the clutch engages

[DLO01]

Also known as thust bearing. Maybe Im just old skool. :p

[Lukezen27]

Yeah but you haven't just had the box a twice in 6 months :(

Clutch died with less than 1000k
Box out a few months later after getting damaged due to the clutch failing

In fact that makes 3 including the HD clutch that died
