Step 11.
Figure 11
Lift the liquid piston away from the
power piston.
Step 12.
Figure 12
Inspect the power piston O-rings for nicks,
gouges, chemical attack or abrasive wear.
Replace worn parts if necessary.
Step 13.
Figure 13
Inspect the liquid piston bore cup seals
for nicks, gouges, chemical attack or
abrasive wear.
Step 14.
Figure 14
If the cup seals are damaged and need
to be replaced, install new cup seals.
When installing new cup seals, cup side
of both seals should face away from one-
another. The cup on the inner cup seal
should face towards the bolt flange on
the liquid chamber. The cup on the outer
cup seal should face towards the valve
ball area of the liquid chamber.
Step 15.
Figure 15
To inspect or replace the discharge
manifold O-ring, valve seat O-ring, valve
seat, valve ball and ball cage, first
remove the combo manifold plate located
at the top of the liquid chamber.
To inspect or replace the inlet manifold
O-ring, valve seat O-ring, valve seat,
valve ball and ball cage, repeat process.
Step 16.
Figure 16
With the combo manifold plate removed,
the manifold O-ring, valve seat O-ring,
valve seat, valve ball and ball cage can
be inspected for nicks, gouges, chemical
attack or abrasive wear. Repeat process
at inlet manifold plate. Replace worn
parts with genuine Wilden parts for
reliable performance.
