To remove the diaphragm assembly from

shaft, secure shaft with soft jaws (aluminum,
plastic, or plywood) to ensure the shaft is not
damaged. Using an adjustable wrench,
remove the diaphragm assembly from the
shaft.

Inspect diaphragms, outer and inner pistons

for signs of wear. Replace with genuine
Wilden parts if necessary.
