Ball Valves;
1. Place the valve in the fully closed position. Note that the slot in the end of the actuator
shaft shows the position of the ball. When the slot is at a right angle to the waterway, the
valve is fully closed.
2. Remove the four socket head cap screws from the gear case cover, and then pull the
cover from the gear case. Rotating the cover slightly will ease removal.
3. Remove the thrust washer and gear segment from the gear case. Note that rotating the
worm slightly will ease gear segment removal.
4. Remove the four socket head cap screws that secure the gear case to the valve body.
Do not remove the stop plate from the actuator shaft.

valve body. Torque the screws to 120-150 in-lbs.

rotating the worm slightly will ease gear segment installation.
8. Apply petroleum base grease to the thrust washer and install.

O-ring.
