Problem with clutch/clutch pedal

bpina4813 · 01-12-2007, 04:56 PM

Ok, the truck in question is an '86 4Runner. Manual trans obviously, 22RE engine.

The truck had been running fine, until I began to notice the clutch engaging much faster off the floor than usual. I noticed it was doing this in my backyard when I was moving some stuff around in it. I parked it. Went to it the next morning, and when I tried to start it with clutch depressed, and in first gear, it began to jump forward with each crank of the engine. Now you can start it and all in neutral (either clutch depressed or not, it still starts), but you can not put it into any gear.

Any help on identifying the problem and/or how to fix it?

TIA

EDIT: And the clutch peddle now has almost zero resistance on it. It moves up and down with no effect.

It's most likely a leak in the hydro system.. First thing to do is check if you've got fluid in your clutch master cylinder.

How many miles? The hydro goes out around 140-160K. I just gone done with mine. The master had no more fluid in it, just a lump of black goo. No leaks. It was working but the pedal was sticking to the floor sometimes. The pushrod was all the way out, too. The disk was almost to the rivets. 1/64" remaining.

i got a friend that has the same problem, except hes replace the master cly. and the slave cly. bleed the whole system many times and still can get the clutch to disengage.

I'm pretty sure there are no leaks. I guess I should start by opening up the master cylinder?

Oh and it has ~155000k on the clock.

FFT:
If it still won't disengage, than the clutch is shot. If the disk is burrowed into the damaged flywheel or the disk is rusted (stuck) to the shaft at the spline than it won't disengage.

I just got done with mine at 145K. $1200 for new clutch kit and cylinders and labor. It it just too cold right now to be under there. And I barely have the time.

It sounds like the master is bypassing or out of fluid by what your telling me.

By the time the clutch won't work, it's dry... Yea, you should start by checking to see if you have fluid.
