Clutch

[clivvy]

mine is working ok but i have this noise when the pedal isnt presssed, just a huffy rattle almost, press itin and it goes away. is this normal, or indicative of some issue or other?

im not worried about it, its been like this since day one, hasnt got worse and gears are faultless!

i was just checking the cost of a newclutch kit, and £120 isnt too bad, but i was curious as to the cost of fitting said kit. if i could get it done cheap enough, then i think id consider getting the clutch done as i plan to keep this car.

Sounds like clutch release bearing to me, as long as the rattle does not get any worse don't worry about it. Don't have the clutch changed until you need to.:thumbs

clutch

mines same some say its the layshaft in the gear box?

 

[clivvy]

cheers Jimmy, ill stick with it, just curious about the noise..

Spider pig, not sure about the layshaft wotsit, i was leaning towards the clutch release bearing, but hey, open to suggestions!

its not a problem at all, just curious, and its good to be for-armed!

clutch release bearings

In my experience you get the most noise from a clutch release bearing when the pedal is depressed partially or fully as that is when it is rotating as the lever operates to release the clutch pressure plate and allows the centre disc to spin freely so you can put it into gear or change gear.

This load on the release bearing be it a bearing or the carbon thrust type of system is what causes a noise when it is worn.

Unless there is no free play in the clutch mechanism the release bearing should be stationary so will make no noise at all. On some vehicles you can get some chatter from the release lever system caused often by general wear in the lever or the fulcrum point that nowadays can be made of nylon or plastic.

Layshaft noises can occur when the car is in neutral as this shaft will be rotating but under no real load so its always a slight noise. When the layshaft or its bearings become worn this noise is usually very obvious as you drive off in the lower gears but will go completely when the gearbox is in direct drive top.

These days this is not when in top gear as they have a drive ratio of less than 1. Typically on 5 speed box the direct drive is 4 th gear and when this is engaged the layshaft has no load on it. If its a 6 speed box then often 5 th will be the direct drive. On 4 speed or less its always the top gear that is the final drive 1:1 ratio.

Hope this helps you decide.

er...

you know your stuff matey.

ill can tell you this much, upon releasing my clutch pedal after changing gear, its sticky...as in i have to flop it up with my foot! i heard that was the spring, but, what do you think??

clutch issue

Okay if the clutch pedal is not coming up without puting your foot under it there are a number of possible causes. If it has a spring in the mecanism this could be broken or detached. Best look at the manual as my motor is an auto !

Not sure if you do any off-roading or jet wash your car but you can have problems if you do as you can get rusting of the clutch disc on its splines this is usually not bad enough to seize the clutch itself but can lead to sticking. On some vehicles you can squirt some WD 40 at the shaft through a timing hole for the flywheel. (Trouble is if it get on the clutch plate it will make it slip and you are done for.)

This in turn will prevent the clutch lever from fully releasing leaving your clutch release bearing under slight load and of course its spinning all the time and it will soon wear out.

If its a cable operated clutch you can get sticking due to wear between the inner and outer cables. Most cars these days have a nylon coating or sleeve at each end of the cable and if water has got past these the cable will rust and stick inside. (If you have a hydrualic clutch you can of course ignore this bit)

On some BMW's the clutch lever fulcrum point is nylon type material and they just wear and that usually results in a loss of ability to release the clutch.

I am sure someone will know the specific operation of your clutch and reply accordingly.

i think this is hydraulic clutch....

i had the same problem with my clutch pedal sticking on my old tdi and it was the nylon pedal bushes that had shot it.replaced them with steel ones and gave them a blob of grease and never had any trouble again.
also you can adjust the pedal free play which also helps.recently done mine and given it a squirt with wd40 as it was squeaking and very annoying.

ill hav ea look at the weekend, perhaps my nylon washer are shot, i couldnt tell last time i looked...!

its a pain in the rear to do.you need to fold yourself up double in the footwell.probably easier to remove the pedal unit.three nuts hold it in place.two in the engine bay at the back of the clutch cylinder and one in the footwell if i recall correctly.then there is the little r clip and pin through the piston at the top of the pedal.
