Unhappy Several questions regarding Clutch system (searched but to no avail...)

First off, on the slave cylinder. HOW THE FAWK do you install it. i screwed it down, but it doesnt even come close to connecting to the fork? is the fork supposed to sit forward (towards the motor) or back (towards the rear of the car) because right now i have to pull it towards the motor for it to do anything. I got the tranny installed by a mechanic and im wondering if this is correct. also, is the pilot bearing inside the eshaft or is it on the tranny? Cuz I'm not sure if they even installed that correctly, because I have a new reman motor and I doubt it even comes with that. Also what size bolts are used to mount the starter?

Thanks guys

Ryan

there's a rod+rubber cover that can fall off the slave cylinder unit.(possibly lost by the mechanic-- i dropped mine twice while mounting the slave to the tranny)

the pilot bearing is in the rear of the eshaft, you have to take the clutch off the flywheel to install/replace ($100+ tool from mazdaspeed to remove pilot bearing)..

as far as the blot size for the starter -trans, ill have to look that up when i get home-- if its even in the book.

I recently read that the starter bolts are the same size but two different thread pitches!

there it is... its kinda crappy and small, but you should get the idea of what a complete slave assembly looks like minus the hose of course.

as the pressure is built up by pressing hte clutch pedal, it forces that rod out, which then pushes against the fork. when installing it, use a little bit of duct tape to keep the rod depressed while you install it. the duck tape with tear as soon as you depress the pedal, but by that time the rod is already in place.

It doesn't pull, it pushes. You're sure you're not mismatching a turbo slave cylinder to an NA tranny, right? The NA slave cylinder's push rod is a good bit longer than the turbo's.

alright, so I guess the fork is sitting in the release position then, because you cant push it forward, its already at the max, it only can be pulled. I guess because since there is no slave cylinder on the fork, its gonna sit back in its release location. or something like that

thanks guys

so, if you could look through the firewall while sitting in the car, the fork is all the way forward?? that makes sense then... with the fork all the way forward, the cluctch is engaged(clutch out)...

when you push the clutch in, the slave pushes the fork twards the driver. the fork depresses the center of the pressure plate with the throwout bearing - thereby releasing the clutch disc from the flywheel. get it?



the fork pivots, so it might not make sense mechanically(especially if you havent been in there). The fork has the throwout bearing on the other end... so when the fork is all the way forward, the other end is more tward the driver.

Just so you know. You are probably not going to be able to disengage the clutch by pushing on it with your hand. Unless of course you are Hercules. The pressure plate clamping pressure is too much to move without the hydraulic assitance.
