Loosen locknut (29) on the pump adjustment mechanism. Slowly turn adjustment screw (30) until the left conveyor does not move. If the conveyor does not stop after turning the adjustment screw one full turn, go to Step 13.
Continue rotating adjustment screw (30) until the conveyor just begins to move. Note the angular position of the wrench. If the conveyor does not move after turning the adjustment screw one full turn, go to Step 13.
Rotate adjustment screw (30) in the opposite direction. The conveyor should stop. Continue rotating the adjustment screw until the conveyor just begins to move in the opposite direction. Note the angular position of the wrench. If the conveyor does not move in the opposite direction after turning the adjustment screw one full turn, go to Step 13.
Rotate adjustment screw (30) to the center of the positions which were noted in Step 9 and Step 10. The conveyor should stop. Hold the adjustment screw in place, and tighten locknut (29) to a torque of 10 N m (7 lb ft).
Go to Step 29.
