Clutch Problem
I have a 1960 f100 I've been restoring now for 6 1/2 yrs. and I'm about 85% complete. I had a 223 & replaced it with a 302.The truck came with a hydraulic clutch and I thought it would be easy to keep. However the hydraulic clutch is my issue. I had the original rod that went into slave cyl & into tranny fork, but with a 302 there's not a lot of room in this area. There is such a short distance from slave cyl. to tranny fork, I cut the old rod trying to make it work, And now the original is way to short. I know that I could make another one, and I have but I'm having trouble with the length that its supposed to be. I have looked in various books ;Dennis Carpenter, LMC etc,but they only list this rod for a 1966 & up.Has anyone had this problem or could I be missing parts, is there an easier solution? Please help, send pics if you have a different set up, Thanks for any responses,twr71

I had similar issues installing the jr cummins 6at in place of a 223. I ended up making a bracket that used the original ford slave cylinder. But for your application let me suggest this. Various manufacturers make a slave clyinder that mounts within the bell housing. It's actually like a hydraulic throw out bearing with no linkage at the 'slave/business' end. No rods, just a telescoping bearing assembly that has a hose going to it and it surrounds the tranny's input shaft. I have never seen or used one, but the guy who was trying to talk me into it says they work very well and available for many different engine/trans setups. I think the main disadvantage is pulling the tranny if the cylinder assembly should ever fail. Most likely summit racing will have something. Just sounds perfect for close clearance stuff like yours.

I had a machine shop make a bracket to mount to bell housing, and bell housing had a bolt hole available to mount this .

When you obtain the new one be sure the piston in the slave cylinder is pushed all the way in when you take your measurement. Don't forget the old saying about measure twice, cut once

That was my question!
Ford put the hydralics inside the bell on their 5 speeds for awhile up till '96 maybe? Personally, never cared for the setup since a leaky slave would also ruin the clutch disc.

for awhile up till '96 maybe?Everything else got a hydraulic clutch in 1984, didn't matter what the M/T was. Hydraulic clutch used thru 1996 or 1997 (F250/350 460/7.3L diesel).
