WHEN SERVICING VALVE:
Replace valve body with ISO-Body Kit if valve has been leaking internally.
Replace motor assembly if the motor will not run or if the printed circuit board is corroded.
Before reassembling valve, remove the coupler shaft from the valve body. Apply Loctite to coupler shaft and
woodruff key. Place the coupler shaft (Ref 7) and the woodruff key (Ref 5) onto the motor shaft. Plug motor
into the valve connector coming from Sprayer Control Console. Check that the motor rotates in both directions.
Motor must stop when coupler CAM releases printed circuit board switch button.
When reassembling valve, grease both sealing surfaces of coupler shaft. Insert coupler shaft into Iso-flange
and be sure seal properly seats on shaft. Install on valve body and apply RTV 738 to mounting holes. Reas-
semble remaining items as shown in parts diagram on opposite side.
