Disassembly / Reassembly
Step 11A
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 11B
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).
NOTE:
Disc spring not shown on
Figure
11B.
Step 12
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 an adjustable wrench,
remove diaphragm assembly from shaft.
Inspect all parts for wear and replace with
genuine Wilden parts if necessary.
