JRV: I have the new clutch at

JRV: I have the new clutch attached in the car. It went in fairly smooth.......had to hit it with a rubber mallet as I slowly torqued down the nuts. It is seated against the flywheel.

The lever arm from the fork shaft does not align with the lower clip of the slave cylinder....no surprise, since this is a new clutch.

The lever arm has about an inch of free movement up and down. In the down position it pushes the throw-out bearing against the clutch. The slave cylinder moves the arm farther down to engage the clutch. I am thinking of positioning the arm where it bearly touches the throw-out bearing, or less. However, then the arm is not at a 90 degree angle to the slave cylinder shaft....it is lower...any movement to engage the clutch will bring the arm even lower.....possibly too low. Do I release the hydraulic pressure, reposition the shaft at 90 degrees to the slave cylinder and then re-fill the hydraulic unit so the "rest" position is now where the fork shaft arm is 90 degrees to the slave cylinder......will this work?

Your thoughts?

Thanks,

Henryk,

too late tonight for me to invision all your info.

I'll follow-up tommorow.

Correct, these are self-adjusting thru PP/Rod Pressure against the Slave Piston, pushing the piston farther in as wear occurs.

>>Do I release the hydraulic pressure, reposition the shaft at 90 degrees to the slave cylinder and then re-fill the hydraulic unit so the "rest" position is now where the fork shaft arm is 90 degrees to the slave cylinder<<

Correct, the rod is supposed to push the piston into the slave housing because what releses the discs is the movement of the arm caused by piston travel. When you release the peddle the pressure (fluid) flows back into the resevore becuase it's pushed by the PP thru the lever arm.

The hydraulics are a simple displacement type, push the peddle fluid travels one direction, let off the peddle the fluid is pushed back.

Does this help ?

JRV: Enclosed is a picture of the final linkage set-up. I had to push the slave cylinder piston about half way up the tube. If I lower the arm to the next notch down, the arm would be angled slighlty downward.....with the piston lower......don't know if I will get enough travel in the slave cylinder to work the clutch properly.

In either case, the pressure from the slave cylinder, at rest, will hold the TO bearing against the PP constantly. I don't think this can be avoided.

Thoughts?

There is no pressure until you push on the peddle, except for the spring in the slave. The clutch works like brakes, when you take your foot off the systen goes back to it's rest position.

From what I see in the photo it should work fine just the way it is. There isn;t a lot of stroke neccesary.

Go ahead and try it and if you have problems we'll figure it out.

You state that there isn't

You state that there isn't a lot of stroke necessary. If the adjustment is such that too much travel occurs, is there a possibility of doing something bad to the pressure plate spring apparatus, as I may inadvertently press the pedal too far to the floor?

Hmmmm...difficult question to

Hmmmm...difficult question to answer without seeing why you think you might have too much stroke. But the short answer is, if the stroke is too long it could push the springs over center, which I believe would cause the fingers to touch on the disc face.

The splines don't allow for setting the rod in infinite postions if memory serves me, as I believe the spline spacing is quite wide (as splines go).

From the picture above the arm in the approx. 90 degree position looks correct. The reason the stroke necc. is short at the slave end is because of the lever and fulcrum design of the set-up. There are actually 2 levers and 2 fulcrums involved, so the outer lever travel (and inner) is in the 1" range. The slave itself internally only has about 2 1/2" - 3" of travel end to end so in the middle of it's range of motion the piston can only push the rod 1"-1 1/2" approx.

If you think there is a problem, in the beggining just push the peddle carefully and slowly to insure there isn't to much travel which will feel like unusual hardness on the peddle end.
