Noise from clutch / gearbox.

Postby imagoodbloke » Sun Apr 16, 2017 5:40 pm

Hi Guys, another question for you experts, when idling in neutral I'm getting a "gritty spinning " noise from bell housing area, it goes away when I engage the clutch. Is it likely to be serious or can I just I ignore it like all the other little noises.
Thank you for any info you can give me. Pete

Hi Woody, thanks for your super quick response, how long do they normally last before they meet their maker, and when it does, would it mean I couldn't select any gears?
Is it a gearbox out job to replace? Please forgive my ignorance, it' s an age thing ! Pete

You could check that the return spring on the clutch arm is still there.

The clutch thrust bearing should normally have some clearance when the clutch is out. (pedal not depressed).

Also check that the clutch pedal is coming fully up, not partially seized on its shaft restricting full movement.

To replace a thrust bearing it is either gearbox out or engine out.

If the gearbox cross member has been welded in like quite a few seem to have been then it must be engine out.

If you have access to a hoist then in my opinion engine out is probably slightly longer but easier.

Hi Custard, thank you for your advise, I've checked the spring and peddle shaft and both are correct. Could adjusting the clutch fix it ? As I understand it the adjuster must move the thrust bearing closer or further from the clutch. Pete

Yes as you tighten the nut on the rod it pulls the thrust bearing towards the clutch.

It should always be clear of the pressure plate when your foot is off the pedal.

The spring keeps it away as long as there is some free travel in the rod.

If you unhook the return spring you should be able to feel the play and see how much it is if you move the end of the clutch arm by hand.

Though you can probably tell when you press the pedal how much free travel you have before you start pressing the clutch.

Hi Custard, I got under the car and had a closer look, whilst the spring was present it was pretty weak and wasn't fully pulling the arm back, I've ordered a replacement, fingers crossed it'll sort out the problem. Thank you for pointing me in the right direction. Pete.
