Reassembly
1.
Install the shaft seals (30‡) in the housing (1). Using
a rubber mallet, carefully drive the bearings (31‡)
flush into the housing so the holes face out. See Fig.
16.
2.
Grease the diaphragm shaft (23‡) and slide it into the
housing (1). Install the o-rings (404*) in the grooves
of the housing.
3.
Assemble the inner diaphragm plates (118),
diaphragms (401*), and outer diaphragm plates (103)
as shown in Fig. 16. Apply medium-strength (blue)
thread locker to the threads of the fluid-side plates
(103), and torque the plates to 75 to 85 in-lb (8.5 to
9.6 N
m) at 100 rpm maximum using a 1/2-in. socket
wrench. Do not over-torque. These parts must be
assembled correctly.
4.
When installing the covers (101), slip the clamps
(111) over the housing (1) before positioning the
covers. See the Detail in Fig. 16. Engage the notches
in the covers with the locator tabs on the housing,
then position the clamps over both parts. The clamp
bolts should be on the air valve side of the housing,
and pointing down toward the bottom of the pump.
Install the grounding strip on the bolts. Apply thread
lubricant to the bolts, then install the clamp nuts
(113). Using a 7/16” socket wrench, torque the nuts
to 50 to 60 in-lb (5.6 to 6.8 N
5.
Reassemble the ball check valves and manifolds as
explained on page 21. Always install new o-rings
(108*), and make sure they are properly seated.
6.
Reinstall the air valve, using the six mounting screws
(15). See F
CAUTION
Do not over-torque the outer diaphragm plates (103).
Doing so will damage the hex heads.
