Evaluating
Components
This procedure applies to the following
parts:
A. Bearing Plate
B. Retaining Ring
C. Feed/ concentrate port
D. Port Retainers
1. Examine these components for corrosion.
For any components not in "as-new"
condition, proceed as follows:
A. Loosen any large deposits with small wire
brush.
B. Place components in shallow container of
soapy water and scrub entire surface
with medium grade ScotchBrite
all corrosion is removed.
C. Rinse components clean with fresh water.
D. Blow components dry with compressed
air, if available.
E. Re-examine components for damage that
could affect structural strength or sealing
properties. Any components not in "as-
new" condition must be replaced.
F. Inspect components for any condition that
might have promoted corrosion, (e.g.
external damage, inappropriate material
selection, etc.)
CAUTION
This procedure for evaluating corroded
components is to be used on any
corroded metal parts. If this fails to bring
any component to "as-new" standards,
the part must be replaced.
