TM 5-3895-371-24 & P
Inspect pump cover (21) bronze face for signs of cavitation, excessive wear, contami-
or other damage. (Refer to fig. 343.) Observe the following:
If circular wear patterns cannot be felt with a fingernail and if there are no nicks
scratches or other surface blemishes, one or two passes across 500 grit emery paper on a lap surface will
put the bronze face in like-new condition. If scratches or the wear pattern can be felt with a fingernail
use 500 grit emery as described above and continue to make passes until wear pattern or scratches can
no longer be felt. Removal of scratches that may cross the lands on either side of the kidney port is
extremely critical. Every effort must be made to remove them.
