TM 5-3895-371-24 & P
(22) Inspect pump cover (21) bronze face for signs
of cavitation, excessive wear, contami-
nation or other damage. (Refer to fig. 343.) Observe the following:
(a) 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.
