Step 10 

  Step 11 

After loosening and removing the outer 
piston the diaphragm assembly can be 
disassembled. 

  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.
