If necessary, the Linkage Assembly is removed and replaced as follows:
1) Remove the Actuator using steps CM45 through CM48 in the previous paragraph titled
ACTUATOR REPLACEMENT.
2) Next, refer to Figure 8-1 (1” to 2” Valves or 8-2 (2 ½” to 4” Valves) to locate item numbers
shown in parentheses in the following steps.
3) Loosen the Hex Nuts (17) under the Indicator Plate (Figure 8-1 or 8-2) approximately a half
turn clockwise.
4) Disconnect the Linkage Adapter from the Valve Shaft (16) by turning the Shaft clockwise
(as viewed from above). If the Valve Shaft cannot be turned by hand, use an open-end
wrench to turn the “double-nuts” on the Shaft until it disengages the Linkage Adapter
threads.
5) Remove the Indicator Plate from the Valve Shaft (16).
6) Remove the two Cap Screws (19) securing the Linkage Assembly (26) to the Valve Top
