6. Slide the valve shaft into the lever. Insert the lever in the opening. Tighten the valve mounting cap screws
(see table 2).
7. Remove machine screws (key 36) and remove the hub (key 29) and the travel indicator scale (key 35).
8. Reposition the hub on the splined valve shaft so that the travel indicator screw holes align with the offset portion
(where the rod end bearing connects) of the lever.
9. Loosen the hex nut (key 145) to allow the valve shaft to slide out of the clamped lever (key 27).
10. Center the lever in the opening. For newer clamping levers, torque the cap screw and nut (keys 28 and 145) to a
torque listed in table 2.
11. With the hub positioned properly, the travel scale and indicator can show the correct position of the valve and point
in the direction of flow when the valve is open. Replace the machine screws, fastening the travel indicator scale to
the housing and the travel indicator to the hub.
