A833 no shift

Clutch not releasing. Z- bar bushings in good shape? Correct pedal to z-bar rod?

What clutch kit did you install? Years ago I had a Hays borg/beck clutch and one of the 3 fingers on the pressure plate would back out of adjustment so the throw out bearing did not contact all 3 fingers equally. Had the same symptoms you mentioned. Progressively got harder to shift, and eventually would only shift through gears while not running. With motor running I could not get it into gear.
