Input shaft bearing?

Yeah I have had release bearing problems in the past. I've also done many clutch jobs. The reasoning behind my statement was that when a clutch it pressed, the bearings in a gearbox stop rotating, thus stop making a noise. I also have the same problem with my EP and had a second opinion given to me by a gearbox specialist in Worcester. I'm only here to try and help the chap, not to argue with people who may well know better than me about their cars.

I very much hope you're right, and that it is a release bearing problem, personally I can't see it, but it would be nice if it was.
 
Just to back up my point:

[h=1]DEFECTIVE CLUTCH RELEASE BEARING[/h]The clutch release bearing separates the flywheel from the clutch disc. If the bearing is defective, it can cause two main problems: 1) The clutch disc will not be able to separate from the flywheel, enabling usage of only a single gear. 2) The clutch disc will disengage at random points while driving, cause the transmission to "slip".

[h=2]Symptoms[/h][h=3]Squealing When Depressing Clutch[/h]A clutch pedal release bearing is what presses down on the rotating spring plate or "pressure plate" to release the clutch disk. Levers and springs in the pressure plate release the clutch from the engine's flywheel separating the power of the engine from the transmission. The Release or "throw-out" bearing, is only engaged when your foot is on the clutch pedal, this means that the bearing is pressing down on the levered springs of the pressure plate and holding them there while rotating at the speed of the engine. When this bearing goes bad you could hear a squealing or screeching noise whenever the clutch pedal is depressed. This bearing is not engaged when your foot is off the clutch pedal.
 
This is clearly a release bearing issue and also springs on clutch plate completely worn out had that problem myself nd a new exedy hyper clucth sorted that problem out!
 
O.k so after a second opinion on my EP from a fellow mechanic, it's the release bearing. I will happily admit when I'm wrong and I was! :lol:

I explained my thinking of why I would have gone with GB bearings, but as EP's are common to clutch bearings an older and wiser friend informed me I was wrong.

Loving the forum by the way guys :)

I will say thanks to everyone for the input, all opinions are welcome glad we have got to the bottom of it and cleared up the confusion :lol:.
 
Ive just had a new exeddy clutch supplyed and fitted and my gearbox re-built with new bearings and seals and gearbox oil for £600 at a honda specialist down near preston, just incase anyone else is needing this kind of work doing, i was getting quotes of around £500-£600 just for the clutch up here near newcastle but then came accross this company. They booked me in for the next day and i drove the 110 miles down they had the car turned round in 5 1/2 hours and job done drove home the same day happy. My clutch was pretty hard and right at the bottom of the travel, would crunch when trying to change high up in the revs and had a wine when rolling in gear from the gearbox. Now the clutch is super soft and gearbox is quiet. Sorted!!!

Would probably be more helpful to others if you actually named this specialist if you're impressed with their work... ;)
 
Fair play for you trying them.

I've not heard good things, however if you are happy with it all credit.
 
Hi

Im looking to re-light this debate...

My clutch has been bad for a while (pressure plate)

Got clutch here ready to do myself.

Ive noticed a noise getting louder and im certain its gearbox input shaft bearing, u can hear it best stood outside the car when its parked infront of a wall

Its making a racket and when clutch is fully pressed in the noise go's completely. Ive only ever know this as gearbox input shaft bearing.
Cause as others have explained when you push clutch in the input shaft shaft stops spinning... its simple logic

Looking on google the only other explanation of noise that gos away when clutch pressed in is a 'pilot bearing'

Fn2 doesnt have a 'pilot bearing' it has a Pilot bushing, theres no spinning bearing there

All info on google for noisy clutch release bearing says the same 'if the noise is there when clutch pedal is fully pressed in then gos away when you let the clutch out, this is a bad / noisy clutch release bearing

Im no expert on fn2, only had mine 7 mths, ive never split a gearbox but after watching several superb and detailed step by step videos on youtube showing k20 gearbox splitting / rebuild / input shaft bearing replacement its pretty easy if your ur used to fixing your own cars were you can

When my box is out im not gonna risk not doing the input shaft bearing and the noise still being there after doing the clutch.

A genuine honda input shaft bearing is around 47quid..

I really cant see grounds for an argument for the noise being there why clutch is out and going away when you press clutch fully in

Only crys 'gearbox input shaft bearing to me'

Diagnosing a Clutch Bearing or Bushing Noise
SKF See more from SKF
The Clutch Release Bearing
This applies force to the release levers or fingers. In doing so, the release bearing disengages the clutch. The release bearing is designed to operate with minimum friction between the rotating and stationary points of contact. If noise develops from the bell housing area, a few checks can be done.

Start with a road test of the vehicle. Listen for noise with the transmission in gear and the clutch pedal to the floor. Next release the clutch with the transmission in first gear. Noise under this condition indicates a worn release bearing or a worn pilot bearing.

To isolate the two, keep the clutch pedal on the floor and shift the transmission into neutral. If the noise persists, the release bearing is bad. If the noise is gone, the pilot bearing is bad.

A bearing noise that occurs when releasing the clutch pedal to engage the clutch while in neutral, but goes away when the pedal is depressed is caused by a bad transmission input shaft bearing.

Always make sure that all other components are in good condition. Check the clutch linkage for binding or mis-adjustments. Check clutch pedal free play and pedal reserve for proper setting. Check the clutch fork and input shafts for proper alignment

Sorry but this is wrong.

If the noise is heard when the clutch is not pressed, and it goes away when it is pressed then it is the clutch release bearing.

This still applies.

I had this on my 3rd EP3. Clutch change and the noise was gone. Many many owners have experienced exactly the same.
 
Thanks chris.

So when clutch is fully pressed in does the clutch release bearing stop spinning completely??

You would think it does as its pressed hard against the pressure plate fingers. But i know the pressure plate is still spinning while clutch is pressed in..

When my box is out i'll have to give the input shaft a wobble see if theres much play in it...

Just found genuine Honda input shaft bearing online for 29.99... 22quid cheaper than tegiwa

For that price im gonna replace mine when gearbox is out regardless..

More info below pasted of google searches that suggest it cant be the clutch release bearing...



****This action allows the pressure plate's springs to force against the clutch disc, engaging the clutch to the flywheel.
Once the clutch is fully engaged,(clutch pedal not pressed in) the release bearing is normally stationary and does not rotate with the pressure plate.****

What are the symptoms of a bad clutch release bearing?
Below are the top 4 symptoms of a bad clutch release bearing.
#1 – Strange Noises. The most common sign of a bad throw-out bearing is when you hear various noises when you depress the clutch pedal. ...
#2 – Clutch Pedal Vibrations. ...
#3 – Gear Shifting Issues. ...
#4 – Clutch is Too Stiff


Question - What noise does a clutch release bearing make?


Answer - The clutch release or throwout bearing depresses the pressure plate fingers, releasing the clutch. It contains a bearing that spins along with the spinning pressure plate as the clutch pedal is depressed. If this bearing is worn, a squealing or growling noise will be heard when applying the clutch pedal
