Thread: Clutch Linkage

Tweet

One of the problems in building the older cars is interior room. I like 3 pedals, so as hard as it is sometimes, and I create most of my own problems, I just like shifting these things.
I have stretched the frame on my truck 3" in the front and 5" on my roadster, knowing there is going to be issues with room. With a 5" stretch it eliminates the problem, 3" does not. Then esthetic's comes into play, I think 5" in a roadster is acceptable but not in a truck, so 3" helps but doesn't eliminate the problem.
One way to give yourself more room is to keep the clutch fork as low as possible on the bell housing and keep the fork as short as possible. So I use a scatter shield with the fork hole rotated down and make my own fork. (I wish Brian would write this maybe it would make more sense)
I hope this helps Some one.

The fork is 1 1/4" shorter, so I use a 3/4" bore on the slave cylinder and 7/8" bore on the master cylinder.

Looks great Ken!!! Is the pressure adequate with the shorter arm? I've gotten even lazier in my old age...... Eliminated the clutch fork all together and went with a hydraulic throw out bearing. Works great on race cars, should be fine on the street, too.

Thanks Dave, I will post a shot of it when it's all cleaned up. I have used the hydraulic throw out bearings without to much success. I found if the car sat for any period of time it would roll the O ring off. I put this same set up in my red roadster and have driven it for a year now without any problems. Easy pedal pressure and plenty of travel.

Good to hear, I've had the same situation arise on the hydraulic throwout bearings, might have to go back to a fork and slave cylinder. I did resolve the issue with some machine work and a larger O Ring. I really like the looks of the aluminum one you made, probably a lot more practical and trouble free for street use then the hydraulic. Hope you don't mind if I steal your idea... My only concern was if the cylinder's would create enough pressure to make everything work correctly, good to learn it all works ok.... Thanks.

Here it is all done.It makes for a nice compact set up, for more interior foot room.

I'll send you a drawing if you want.
