What was found
(CAN) PUMP WAS SENT FOR OVERHAUL. INTERNAL INSPECTION REVEALED THAT THE ARMATURE HAD BEEN MODIFIED BY REDUCING THE ARMATURE SHAFT SIZE AND SUBSTITUTING THE ORIGINAL BEARING WITH A COMMERCIAL BEARING THAT HAD THE SAME OUTSIDE DIAMETER, BUT A SMALLER INSIDE DIAMETER,TO ACCOMODATE THE REDUCED SHAFT SIZE. THE COMMUTATOR END BELL (PN 67824) HAD ALSO BEEN MACHINED TO ACCEPT A BEARING LINER IN THE END BELL. DUE TO OTHER PROBLEMS WITH THE PUMP, THE UNIT WAS DEEMED BEYOND REPAIR. UNIT REMOVED FROM SERVICE.
