An improved release mechanism for a hydraulically operated clutch. A tubular cylinder is formed between stationary inner and outer housings. A tubular piston has an inner end extending into the cylinder and has an outer end mounting a thrust bearing. Rotating clutch release levers engage the thrust bearing. One or more radial holes extend through the piston adjacent the inner end. Pins positioned in the holes extend into inner housing grooves which extend parallel to an axis of the release mechanism. The pins and grooves prevent rotation of the piston relative to the stationary housings, while allowing axial piston movement. A retainer ring is positioned in an annular groove in the exterior of the piston. The retainer ring both retains the pins in the piston holes and retains the piston in the cylinder.
