Step 8. Figure 8
Using a 25 mm (1") box wrench, adjustable wrench, or by
rotating the diaphragm by hand, remove the diaphragm
assembly.
Step 9A. Figure 9A
NOTE: Due to varying torque values, one of the following
two conditions may occur: 1) The outer piston, diaphragm
and inner piston remain attached to the shaft and the entire
assembly can be removed from the center section.
Step 10. Figure 10
To remove the diaphragm assembly from the shaft, secure
shaft with soft jaws (a vise fitted with plywood or other suit-
able material) to ensure shaft is not nicked, scratched, or
gouged. Using an adjustable wrench, remove diaphragm
assembly from shaft. Inspect all parts for wear and replace
with genuine Wilden parts if necessary.
Step 9B. Figure 9B
2) The outer piston, diaphragm, and inner piston separate
from the shaft which remains connected to the opposite side
diaphragm assembly. Repeat disassembly instructions for
opposite liquid chamber. Inspect diaphragm assembly and
shaft for signs of wear or chemical attack. Replace all worn
parts with genuine Wilden parts for reliable performance.
