Squeaky Clutch - How To Fix?

[chicane]

Hi All,

Got this annoying problem with my R33 - when I push the cluch pedal in it makes a squeak noise - you can hear it quite loudly outside the car.

Any tips on fixing this? It sounds like its coming from the engine bay rather than in the cabin.

Tnx!

can you get someone to press it for you, and then stick your head under the car? (car off obviously)

Maybe it could be the slave cylinder pushing on the fork? As far as the engine bay goes, your pedal is hooked onto a rod that pushes through the firewall and into the clutch master cylinder. That rod could make some noise possibly? I don't know if it is lubricated by the clutch fluid in the reservoir.

Anyway, isolate where it is coming from, then you might find you need a master or slave cylinder reconditioned. Personally, my clutch pedal's spring was VERY loud until I took to it with some silicone lubricant.

I had this problem recently, ended up being the clutch fork just needed some lubrication.

same prob here it was clutch fork. Supposedly to reach the clutch fork its a pain in the butt thing to get too.

I used a flexible piece of small diameter hose attatched to a cannister of silicone based lucbricant and just fed the hose (around 45cm) to the clutch fork and gave it a nice little spray, seemed to work fine.

you will want to put something that will stay there on it. like grease or something similar. the main spot it squeaks from is where the clutch forks sits on the pivot bolt. if it gets really dry then you don't drive it for a while (month or so) when you next put your foot on the clutch, if they have rusted together it will snap the pivot bolt. i have my bolt snap, and its a few hours work to get the gearbox off and back on, but only cost me 90 cents to fix it. mine broke off at the bell housing so we had to use a tool to get the thread out. a guy i know with another r33 had his break right at the fork and it ended up stuffing his clutch as well.

to lube it up get some grease on the end of your finger, get under the car on the drivers side, and you will see a lever coming out of the gearbox. that is the clutch fork. on the side opposite to where the slave cylinder pushes on it you can slide your finger in there and apply the grease.

apparently snapping pivot bolts is common on skylines, especially when the clutch has been replaced. the mechanics over tighten the bolt. they need to be firm, but not over tight. will thry to take a pic of where i am talking about tonight.

thanks heaps for that mad82, and ya if u can pic would be gr8

Awaiting pics as I have started to get the squeek with the onset of colder weather, bleh =\

[mad082]

will try to get a pic tonight. by the time i got home last night it was to dark and cold.

[mad082]

here is the picture. the pivot bolt is about 2 inches in behind that soft bit.

the picture is taken from the drivers side. if you stick your head under the car just behind the front wheel that is what you'll see.

[mad082]

a spray grease or grease gun with a hose would make the job easier. but any lube is better than nothing, but the thicker the better as it will stay there longer and lubricate better. also worth putting a bit on where the slave cylinder pushes on the clutch fork.

[No Crust Racing]

Yeah I looked at all that. So you can get your finger in under that grommet to get some grease in there?

Does you go in behind the fork as in closer to rear of car or in front?

Cheers

the rear. the left of the photo is the rear. the bit where the arrow points to is just a tab.

[No Crust Racing]

Sweet, I've got a grease gun so will have a poke in there and see how we go. Cheers for tha pic.

[mad082]

no worries, hope it helps.

just discovered that UAS (unique autosports) do replacement pivot bolts. they are supposed to be stronger than stock, but they are $55.

i had this problem, thou greased basically everything possible (btw when u do this make sure u don't spray ur clutch plate!!), still didn't go. ended up having to remove box replace the pivot release ball and withdrawl lever, they had excessive movement in them causing a metal on metal kinda squeak. Also replaced clutch slave cylinder at same time, cause mid bleeder went only a few weeks earlier and once one goes, generally they all start to fail at same time.
