Reversing Float Action Figure 2 shows the lever arrangement for first-class and second class lever arrangements. For first-class levers, the fulcrum is located between the valve stem connection and the float rod assembly. For second-class levers, the fulcrum is located outside the distance between the valve stem connection and the float rod assembly Key number locations are shown in figures 3 and 4 unless otherwise indicated. To change an existing float action from a first-class to a second-class lever, or vice versa, perform the following steps: 1. Remove the lever arm (key 9 or key 12, figures 3 or 4) from the actuator by removing the E-rings (key 5) and the lever pin (key 6).
