## Discrepancy

THIS PROBLEM IS WITH THE INSTALLATION OF AN IFS AIR CONDITIONING.  VISUAL INSP REVEALED A NICK MID WAY UP THE LT AFT MGB SUSPENSION BAR.  THIS IS WHERE THE IFS COMPRESSOR PULLEY AND CLUTCH ROTATES, CURRENTLY WITHIN ABOUT .1875" CLEARANCE TO THE BAR.  DAMAGE TO BAR WAS WITHIN PUBLISHED LIMITS AND REPAIRED.  AIR CONDITIONER COMPRESSOR ASSY MOVED FWD SLIGHTLY WITH WASHERS AT MOUNTING POINTS WHILE MAINTAINING THE ALIGNMENT WITH PULLEY AND DRIVESHAFT TO INCREASE THE CLEARANCE. THE BAR, AFTER REPAIR WAS ROTATED 180 DEGREES AND INSTALLED . CLEARANCE IS NOW APPROX .3125 BETWEEN THE AC COMPRESSOR AND BAR. THIS AREA WILL BE MONITORED WITH A DI.
