Disassembly / Reassembly
Step 8A
NOTE:
Due to varying torque
values, one of the following two
situations 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 8B
2) The outer piston, diaphragm, inner
piston, and disc spring separate from the
shaft which remains connected to the
opposite side diaphragm assembly PTFE-
fitted pumps come standard with back-up
diaphragms (not shown).
Step 9
To remove the diaphragm assembly from the
shaft, secure shaft with soft jaws (a vise
fitted with plywood or other suitable material)
to ensure shaft is not nicked, scratched, or
gouged. Using a wrench, remove diaphragm
assembly from shaft. Inspect all parts for
wear and replace with genuine Wilden parts
if necessary.
