## Discrepancy

THE CHROME PLATING ON THE CHAMFER IS CHIPPED OFF CAUSING CHROME PARTICLES TO FLOW THROUGHOUT THE INSIDE OF THE UNIT.  THIS WAS CAUSED WHEN THE FWD PISTON (FIG 1103 IT. 14) WAS TORQUED ONTO THE AFT PISTON AND THE CHROME ON THE CHAMFER CHIPPED OFF DUE TO PRESSURE.  RECOMMENDATION:  HAVE ZERO CHROME RUN OUT ON CHAMFER WHEN RECHROMED.
