## Discrepancy

THE GREASE APPLIED TO THE ACTUATOR IS NOT WHAT IS SPECIFIED IN THE MANUFACTURER'S OHM (GENERAL DESIGN, 28-20-03).  THE LUBRICANT USED IN THIS UNIT'S GEAR TRAIN HAS EMULSIFIED AND MIGRATED INTO THE MOTOR ASSEMBLY.  THE MOTOR ASSEMBLY IS CONTAMINATED WITH GREASE WHICH APPEARS TO CAUSE POOR CONDUCTIVITY BETWEEN BRUSHES AND MOTOR ARMATURE COMMUTATOR.  RECOMMEND:  USE CORRECT GREASE IAW OHM INSTRUCTIONS.
