Placement of the Rocker Arm
In this image: The yoke of the rocker arm must be under the arms of the bell and the rocker arm secure on the notch of the base plate.
Screw on the nut until it lightly touches the rocker arm to help loosely secure the rocker arm to the base plate. If necessary, see the section about Gomco Clamp Inspection for a review of the names of the parts of the clamp.
