VEHICLE DESCRIPTION: TRANSIT AND SHUTTLE BUSES EQUIPPED WITH CUMMINS ISC AND ISL DIESEL ENGINES. THE INTERNAL FRONT BUSHING CAN SPIN, CAUSING DAMAGE TO THE AIR COMPRESSOR, AND POSSIBLY TO THE SPINDLE DRIVE AT THE REAR FACE OF THE AIR COMPRESSOR WHICH IS USED TO PROVIDE POWER TO THE VEHICLE HYDRAULIC PUMP. FAILURE OF THE AIR COMPRESSOR'S SPINDLE DRIVE COULD LEAD TO LOSS OF POWER ASSIST IF THE HYDRAULIC PUMP CEASES TO OPERATE.
WITHOUT POWER ASSIST, THE VEHICLE BECOMES VERY DIFFICULT TO TURN AND COULD POSSIBLY RESULT IN A VEHICLE CRASH.
