1995 International Harvester 4700

ON CERTAIN HEAVY DUTY TRUCKS EQUIPPED WITH BOSTROM DRIVER SEAT MODELS 910, 910SC, OR 914 AND INTERNATIONAL'S PARKING BRAKE CODE 04036, IF SOMEONE OUTSIDE THE CAB ADJUSTS/SLIDES THE DRIVER'S SEAT TO ITS MOST FORWARD POSITION, WITH THE PARKING BRAKE SET, THE SEAT WILL CONTACT AND RELEASE THE PARKING BRAKE LEVER.

RiskIF THE PARKING BRAKE IS ACCIDENTALLY RELEASED, THE VEHICLE COULD MOVE UNEXPECTEDLY, INCREASING THE RISK OF A CRASH.

Fix DEALERS WILL INSTALL A STOP-BRACKET ON THE SEAT TRACK TO LIMIT THE TRAVEL OF THE SEAT SO THAT THE SEAT CANNOT RELEASE THE PARKING BRAKE LEVER. OWNER NOTIFICATION BEGAN ON MARCH 31, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT INTERNATIONAL AT 1-800-448-7825.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS. THE VEHICLES INVOLVED IN THIS RECALL WERE BUILT FOR EXPORT WITH MANUAL SLACK ADJUSTERS AND WERE SOLD IN THE US. THESE VEHICLES NEED TO HAVE AUTOMATIC SLACK ADJUSTERS IN ORDER TO COMPLY WITH THE REQUIREMENTS OF FMVSS 121, "AIR BRAKE SYSTEMS."

RiskTHESE VEHICLES DO NOT COMPLY WITH THE STANDARDS.

FixDEALERS WILL REPLACE THE MANUAL SLACK ADJUSTERS WILL AUTOMATIC SLACK ADJUSTERS.

AT LOW AMBIENT TEMPERATURE, WITH THE PARKING BRAKE APPLIED ABD THE ENGINE RUNNING, PRESSURE CAN BUILD UP SUFFICIENTLY TO PARTIALLY PRESSURIZE THE BRAKE CHAMBER WHICH CONTROLS THE DDM PARK BRAKE AT THE REAR OF THE TRANSMISSION ALLOWING THE PARKING BRAKE TO PARTIALLY RELEASE.

RiskIF THE VEHICLE IS PARKED ON A MODERATE INCLINE, THE VEHICLE CAN ROLL AWAY WITHOUT WARNING AND POSSIBLY RESULT IN AN ACCIDENT.

FixDEALERS WILL RE-PLUMB THE HYDRAULIC LINES OF THE HYDRAULIC PARK BRAKE SYSTEM PREVENTING UNINTENTIONAL RELEASE OF THE PARK BRAKE.

THE BASE OF THE ELECTRONIC ACCELERATOR PEDAL IS MADE OF DIE CAST ALUMINUM. THE BASE MOUNTS DIRECTLY TO THE CAB FIREWALL. THE CAB FIREWALL IS NOT RIGID ENOUGH OR FLAT ENOUGH AT THE MOUNTING SURFACE, CAUSING STRESS ON THE ACCELERATOR BASE THAT WILL CAUSE THE MOUNTING PADS ON THE BASE OF THE PEDAL ASSEMBLY TO FAIL AND TOTALLY SEPARATE FROM THE FIREWALL.

RiskTHIS CAN CAUSE LOSS OF SPEED CONTROL, DRIVER DISTRACTION, AND RESULT IN AN ACCIDENT.

FixDEALERS WILL INSPECT THE ACCELERATOR PEDAL ASSEMBLY AND INSTALL A PLATE BETWEEN THE ACCELERATOR MOUNTING BASE AND THE FIREWALL ON THOSE UNITS WHERE THE BASE IS NOT BROKEN AND HAS NO VISIBLE SIGNS OF A CRACK. IF THE BASE IS BROKEN OR CRACKED, THE ACCELERATOR ASSEMBLY WILL BE REPLACED WITH A NEW REDESIGNED ACCELERATOR PEDAL ASSEMBLY.

FOUR COMPRESSION BACKPLATE RETAINING FASTENERS ON THE TURBO-CHARGER WERE TORQUED ONLY HAND TIGHT. THIS ALLOWS THE FASTENERS TO LOOSEN, AND CAUSES OIL TO LEAK INTO THE COMPRESSOR AIR SIDE OF THE TURBO-CHARGER WHICH, WHEN COUPLED WITH THE HEAT PRECIPITATED BY THE COMPRESSOR AND THE MIXING ACTION OF THE COMPRESSOR WHEEL, CAN RESULT IN AN AIR/OIL MIXTURE THAT FUELS THE ENGINE.

RiskWHEN THIS OCCURS, ENGINE RUN-ON AND SUBSEQUENT LOSS OF OPERATOR CONTROL VIA THE NORMAL THROTTLE MECHANISM CAN OCCUR, WHICH COULD RESULT IN A VEHICLE ACCIDENT.

FixREPLACE THE SUSPECT TURBO-CHARGER WITH A NEW TURBO-CHARGER.
