Clutch Slave Cylinder

[bob w]

I'm about to mount the slave cylinder for the clutch in my roadster pickup. It is a push-type cylinder. when the clutch is at rest should the pushrod push the piston in the slave cylinder all the way back? Or should it stop short of fully pushing all the fluid out of the slave cylinder?

It needs to stop short so, as the clutch disc wears, the clutch arm has room to move back farther.

Only one I ever had was on a Toyota pickup, IIRC it had an adjustable rod, you set it so it had a small amount of free play, just enough the rod would spin in the fork arm socket. When I put a Buick V6 and Saginaw 4 speed in the same Toyota pickup, I used the Toyota slave and made a new rod. Adjusted it the same way, worked great.

You don't want the throw out bearing to be rubbing the pressure plate all the time, so make sure it has a enough travel to prevent that.

I've had a hydraulic slave cylinder on my 27 for about 30 years, and it works great. I put a very heavy spring on the outside of the throwout arm to pull the rod back into the cylinder. It retracts all the way. The spring keeps tension on the rod so you can adjust it with some play, just like a mechanical setup.

Hope this helps, Bob.
