Pull the transmission out, remove the clip on the throw out bearing, slide bearing off, carefully pull on the fork and it will pop off. Using a socket, remove the ball that the fork was on, put a washer on the pivot ball threads and put it back on.

so you cant just put a washer between the slave rod and the fork to extend the reach of the slave rod to push the fork further?

I suppose you could but that could then make the fork hold pressure on the bearing and pressure plate at all times. What exactly is the problem that makes you want to modify it?

my clutch pedal does not start to disengage till about an inch from the floor. i replaced the master and slave then bleed the system. no luck. i was looking at the clutch fork and its just barely off center to the passenger side of the car. i think it is worn out. i have not done the pedal assembly check yet, i will go check the pedal assembly now and get back here asap. thanks.

also when it comes back up from the floor about halfway up it feels kinda springy and sort of sticks/pops back all the way up.

ok, so i just checked the pedal assembly. it is ok. it comes all the way back up from the floor and when you push it in it immediatly moves the push rod with it with no delay.

I just re-read your post and it engages right near the floor...sorry. Maybe a bent fork?

You still have air in the system. bleed it again, but this time use a hose and a bottle on the nipple on the slave. Or you can get a 1 man bleeder kit from autozone. You have to pull the pedal up all the way when you are bleeding it.

you dont think it has something to do with the clutch fork leaning a little to the passenger side and the slave not being able to push it far enough?

if its a bent fork the a shim between the slave rod and fork should work right?

Its not the best. But you saying that the pedal pops back up about halfway leads me to believe that there is still air in the system. Try that first before you go poping off the tranny to shim the pivot ball.

What kind of clutch do you have? if you are still on a stock style clutch i wouldn't worry about a bent release fork, and from my experience they don't bend they break. Try bleeding it again, it will only take 5 Min's to do. Sometimes they are hard to bleed.

I am not sure if I am just confused by what you are saying or if you are confused by what the original poster said. You do not need to lengthen the rod on the slave cylinder to shim the pivot ball. The pivot ball is located inside the bell housing of your transmission. It sort of looks like a tesla coil in that it is a round ball machined onto a stud that is threaded into the trans. This piece is located directly behind the clutch fork and it is what the clutch fork pivots on. To shim it all that you have to do is unbolt the pivot ball, place a washer behind it, and then re-install it. It still sounds like you have air in your system though.

I would first try to bleed the crap out of the system because it's the easiest plan of attack. If your fork is in off toward the passenger side of the tranny in the access hole, it sounds like you have either a bent fork (unlikely) or a worn pivot ball. In either case you will have to pull off the tranny to fix it, and either replace the fork or shim the pivot ball.

I found out awhile ago that this (more commonly the "extended slave rod") does nothing to help you. If you install an extended slave rod or lengthen the one you have, the system will re-balance itself out after the install, and you will have the same amount of "push" as you did with your shorter push rod.

The other EASY thing to do that I hope you already tried (although I didn't see it mentioned) is to simply adjust your clutch. If your clutch is out of adjustment it will cause you to have an improper clutch engagement point. Good luck to you!

ok guys thanks for all the help. today me and my uncle got together. he's a mitsu tech, me being a nissan tech, anyway we have determined that they took to much off my flywheel so i asked them how much they took off to clean it up and they said 25 thousands. wow! theres the problem, it i set back so far that i need a new flywheel or shim the pivot due to to much slack to fill before being released. however my clutch does work good as long as you put it all the way to the floor so i will just use it as is till my next clutch job. thanks for all the help guys.
