How do you adjust the hydraulic clutch slave cylinder on a 1987 f-250., and can they be bled.

 

internal or external ? External no bled port. But you can push the rod in on cylinder, lock it in. Fill master, unlock the rod and it should move outward, pulling fluid in. Hold slave cylinder with tubing at highest point an push the rod back in, lock it. Check the fluid in master cylinder, fill. And repeat, until air does not come back to the master cylinder.

If there is no adjustment screw type end on the slave cylinder there is no adjustment.

But if the clutch is not disengaging, Check the arm on the shaft the clutch peddle operates, that attaches to the master cylinder rod.

You can loosen the bolts that hold the clutch master cylinder to the fire wall. Push the master cylinder out away from the fire wall about 1/4 to 1/2 inch.

Loosen the nut that holds the arm on the shaft. Knock the arm off the spline part of the shaft. Make sure the clutch peddle is all the way out, or back toward you.

Push the master cylinder rod in by hand, just to take any slack out of the cylinder rod. It is very hard to push in so just take the slack out.

Line the arm up on the peddle Shaft, with the peddle all the way out and the slack out of the master cylinder. Bump the arm onto the shaft, and tighten the nut that holds the arm to the shaft.

Tighten the bolts that hold the master cylinder to the fire wall.

 

Thank you, I'll try that this weekend.
