Clutch Issue

[efertsman]

Hey guys... and girls if there are any...
I am new to this mistubishi forum in search for a few tips on an issues with a recently purchased (summer 2010) car (Evolution 1 CD9A 1992). I've spent a good amount of time on the forum in search of similar problems, however havent stumbled upon anything of usefull help.

Since ive bought the car i;ve been fiddling, and adjusting the clutch to remove low clutch engagement, which is having a toll on my gearbox. Reverse grings unless I really step on the clutch pedal, and shifting directly into first from neutral also grinds unless i push that clutch really hard. With every other car ive driven, when realasing the clutch from the floor, the clutch tends to engage (or disengage, might have my terms mixed up) towards the end of the pedal travel. This clutch is engaging strait off the floor.

I;ve bled the clutch system a few times
I've also adjusted the clutch pedal by the clevis (bolt going from the pedal to the cylinder)

Adjusting the clutch has not changed the points of which the clutch engages.

Another thing i've noticed, is that there is a crunch sound when pushing the clutch pedal. Ive always thought this was normal, since many imports around (Nova Scotia, Canada) are making the same sound. But their setups are fine.

the symptoms you describe are common to a worn pivot ball and fork. unfortuneately that means removal of the gearbox to correct this. the best remedy is a new fork and ball but you can sometimes get away with placing a 2mm thick washer under the pivot ball.

the crunch in the clutch pedal usually indicates a broken pedal mount and sometimes even worse a crack in the fire wall. the crack will be visible from the engine bay and normally goes from the hole that the clutch master cyl protrudes from across to the hole for the speedo cable

I see your point about the crack in the firewall or broken clutch pedal bracket. However when we were bleeding the clutch, the sound seemed to be coming from the gearbox itself. AND after being bled a few time, the noise only apears after the car had been driven, or after things have warmed up.

Try some OEM gearbox fluid (DiaQueen) and replace your slave cylinder with and the fluid in that system too. Worked wonders in my old RVR with a W5M33 gearbox.

Not sure about where you'd source the DiaQueen locally but the salves should be the same as a 2g surely?

Replacing Gearbox fluid is a must for sure. I'm thinking its never been changed.
After doing more research, i've figured perhaps shimming the pivot ball and fork is the only way to go. The fork is leaning away from the slave cylinder when you look at it from underneath, instead of being in the middle, probably almost hitting the bell housing.
Now if i could only get some guidance as to what im getting myself into if I decide to take off the tranny ^_^

what do you mean it worked wonders for you? Where you experiencing any of the same symptoms as me?

Could the clutch be on the way out?? I had a similar problem in one of my cars and found that one of the springs from clutch plate had rattled loose and got stuck between the fingers of pressure plate(hard clutch pedal) and flywheel and it made a noise once it warmed up..... :unsure:

Im not sure, clutch seems to grab pretty good. I've owned some 240's with pretty bad clutches, and this doesnt feel close. Either way, i guess i'll see once i have the box out. Thats really the only way to tell... Car is in till the spring, so i figure its a good time B)

Fucked pressure plate. replace

I would say bent pressure plate fingers or worse case clutch fork is bent, not given you proper travel.
It happened in my VR4 once, gear selection became difficult even with adjusting. Clutch bite point would constantly change...then finally the clutch forked snapped on a normal change.
