## Discrepancy

(CAN) PINS ON SPECIAL WASHER SHEARED ALLOWING BODY OF HYDRAULIC SWIVEL FITTING TO ROTATE ON GEAR RETRACTION/EXTENSION BREAKING HYDRAULIC LINE TO THE BRAKES P/N 5324412053. THIS APPEARS TO BE CAUSED BY TO THICK OF A SPACER WASHER P/N 532.10.12.136 WHICH CAUSES THE ASSEMBLY TO APPLY TO MUCH FORCE TO THE SPECIAL WASHER AND ITS PINS. FOUR THICKNESS'S OF WASHERS ARE AVAILABLE IN THE IPC BUT NO PROCEDURE I S SPELLED OUT IN THE MM FOR THE TECHNICIAN TO HELP HIM/HER DETERMINE IF THE PROPER GAP IS THERE ON ASSEMBLY.
