I read the SII and hydro post and got to thinking what i want to do with my 66. at first i wanted to just go all manual with the clutch, but i somehow ran out of room for the pivot ball and all the linkages need real quick. i decided on hydro to avoid all that. now, what ixactly is the difference....lame question yes, but im a bit confused on how it diffrers from the manual set up.

here is what i know.

from the clutch pedal there is a rod that connects to a master cylinder booster and master cylinder....not sure what a slave cylinder is........this is much like the way brakes work right? from there fluid is pushed out of this master cylinder through a braided line or hydro line of some sort into a hydro ram (this is the slave cylinder??) which is mounted near (infront of the clutch fork, usually in the place of the pivot ball and a bolt farther up on the bell houseing) this ram in turn pushes..or pulls... on the clutch fork and you have engaugment and disengaugment.

Correct?

now i would be using the stock 1966 brake and clutch pedal set up. will this work with a hydro set up? it should if i adjust the master cylinder to push fluid though the entire rage of motion on my stock clutch. it shouldnt matter how far the stock clutch swings because the hydro clutch will exagerate the movement or conserve the movement to the clutch to whatever i want it to do depending on how i tune it?

correct again.....i really dont know, im just guessing.

now if im right, what is needed to do this to a stock, non hydro sm465.

ill need a master cylinder, a booster, a slave cylinder (the hydro ram?) some hydro lines. some way to mount the slave cylinder to the bellhouseing.........will i need a different bellhousing? my clutch pedal will work? and ill need some sort or resevoir for the fluid also correct?

please help me....and give me some $$$ numbers too if you can.

maybe this will help others as well.

thanks a lot,

You need a clutch master cylinder and a matching slave cylinder. There is no booster. You mount the master to the firewall and the slave to the transmission. Post up in General 4x4 or search in the Gen, Jeep and the Land cruiser sections for info on SM465 hydro clutch, its been done thousands of times. Search should help you find a good donor for the clutch master and slave cylinders, or you could use wilwood stuff from any of the race car parts places (http://www.speedwaymotors.com) Mounting the master and slaves is going to require fabrication and calculations on your part to make sure you get the throw ratios right so you use all the travel available in the cylinders and don't end up with a stiff pedal or not enough throw.

thanks, i have a guy that wants to sell me the correct master and slave cylinders. i may just buy those.

thanks again. i see mow how it works. i was wondering now, how is it that i can get the same throw out of my Scout 800 clutch pedal as i would get out of a stock chevy with the same set up? one guy seggested that i measure the throw on a stock chebby and then measure that on my pedal, then drill a new pivot hole in my clutch to match that of the stock chevy.

OR

what if i just use a stock chebby master and slave cylinder and just adjust the push rod length so that it disengauges the throwout bearing the correct distance?

help?
