5.
Inspect the valve plate (110) in place. If
damaged, use a Torx (T20) screwdriver or 7 mm
(9/32) in.) socket wrench to remove the three
screws (107). Remove the valve plate (110).
6.
Inspect the bearings (113, 115) in place. See
. The bearings are tapered and,
if damaged, must be removed from the outside.
This requires disassembly of the fluid section.
See
Center Section Repair, page 17
7.
Clean all parts and inspect for wear or damage.
Replace as needed.

If
repairs
involve
removal
of
fluid
covers,
these
steps
will
ease
installation
of
fluid
c overs.
These
steps
should
be
performed
prior
to
reassembly
of
the
air
valve
because
the
air
valve
configuration
will
be
modified
to
aid
fluid
cover
installation.
The

is
available
separately
.
1.
If the air valve assembly has not been
disassembled:
a.
Remove the air valve cover (109) and gasket
(118).
b.
Remove the valve cartridge (105) and both
pistons (114).
c.
Insert the travel restrictors (2) from the
diaphragm install tool kit into the actuator
pistons (E). Lubricate the u-cups and insert
the actuator pistons in the bearings (115),
wide
wide
wide
end first. Leave the narrow end of the
pistons exposed.
d.
Proceed to step 4 below.
2.
If the air valve assembly has been disassembled,
perform step 1 through step 4 of the air valve
reassembly procedure.
3.
Install the u-cups (106) onto the actuator pistons
(E) and insert the travel restrictors (2) from the
diaphragm install tool kit into the actuator pistons
(E). Lubricate the u-cups and insert the actuator
pistons in the bearings (115),
wide
wide
wide
end first.
Leave the narrow end of the pistons exposed.
4.
Install the supplied diaphragm install tool (1) so
that the arrow (A) points toward the side of the
pump with the diaphragm against the air cover.
Install the air valve gasket (C) and cover (B).
Snug the air valve cover screws.
5.
Lubricate the inner surface of both cover clamps
with waterproof sanitary lubricant. Install the
cover and clamp on the side of the pump with
the diaphragm against the air cover. Leave the
clamp slightly tightened but loose enough to
allow minor cover rotation to allow for alignment
with the inlet and outlet manifolds.
6.
Supply the pump with low pressure air, just
enough to move the diaphragm. Use about 10 to
20 psi (0.07 MPa, 0.7 to 1.4 bar). Shop air may
be used. The diaphragm will shift so the second
fluid cover will seat properly. Keep air pressure
on.
7.
Install the remaining fluid cover and clamp.
8.
Remove air supply from pump.
9.
Remove the air valve cover (B), gasket (C) and
the tool (1).
10. Remove the pistons (E) and the travel restrictors
(2).
11. Lubricate and install the pistons (E).
12. To complete assembly of the air
valve assembly, proceed to step 6 of
.
