LINKAGE ASSEMBLY REPLACEMENT
As Figure 8-6 shows, the Linkage Assembly Part No. will vary, depending on valve size. CXT-E valve
sizes from 1.00 to 3.00 inches utilize Linkage Assembly Part No. 24038-1. However, 4.00 inch CXT-E
Valves utilize Linkage Assembly Part No. 24038-2. The primary difference between the 24038-1 and
24038-2 Linkage Assemblies is the Adapter shown in Figure 8-6. In addition, the Linkage Pin location for
the 24038-1 assembly will vary for 1.00 to 2.00 inch valves and for 2.50 to 3.00 inch valves. IT IS
IMPERATIVE THAT THE CORRECT ADAPTER AND PIN LOCATION BE USED FOR THE VALVE SIZE
BEING REPAIRED. The Linkage Assembly is attached to the Control Valve Top with two Cap Screws.
The Linkage Gasket (Part No. 81046) should also be replaced when installing a new Linkage Assembly.
