1975 International Harvester Transtar Series

AS A RESULT OF SEVERE SHOCK AND VIBRATIONS, THE BRAKE SPIDERS ON THE INVOLVED VEHICLES MAY DEVELOP CRACKS NEAR THE CAMSHAFT MOUNTING BOSS. THE CRACK PROPAGATES ACROSS THE SPIDER UNTIL THE CAMSHAFT BOSS IS COMPLETELY SEVERED FROM THE REMAINDER OF THE SPIDER. WHEN THE CAMSHAFT BOSS HAS COMPLETELY SEVERED, THE S-CAM, S-CAM BRACKET, AIR CHAMBER AND SLACK ADJUSTER CAN FALL AWAY FROM THE BRAKE SPIDER RESULTING IN A "NO BRAKE" CONDITION ON THE WHEEL.

FixTHE DEALER WILL REPLACE THE FRONT BRAKE SPIDERS ON ALL AFFECTED VEHICLES USED IN SNOW PLOW DUMP AND REFUSE HAULING APPLICATIONS. THIS WILL BE DONE AT NO CHARGE.

THE INVOLVED VEHICLES DO NOT CONFORM TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS". THE WASHERS USED TO SPACE THE ANTI-LOCK SENSOR BRACKET AWAY FROM THE BRAKE SPIDER WERE OMITTED DURING ASSEMBLY. THIS OMISSION COULD CAUSE THE SENSOR BRACKET TO BE DEFORMED. BRAKING CAPABILITY COULD BE PARTIALLY LOST.

FixTHE DEALER WILL INSTALL TWO WASHERS AND REPLACE SENSORS AND AIR CONTROL VALVES ON ALL AFFECTED VEHICLES.

THE DEFICIENCY EXISTS IN THE FRONT AXLE FORGED ALUMINUM HUBS. THE DEFICIENCY WHICH IS IN THE BARREL SECTION BETWEEN THE INNER AND OUTER BEARING, MAY RESULT IN CRACKS WHICH COULD LEAD TO HUB FAILURE. WHEN HUB FAILURE OCCURS, THE SEPARATED HUB IS RETAINED ON THE AXLE SPINDLE BY THE WHEEL BEARING AND ADJUSTING NUT.

FixTHE DEALER WILL REPLACE THE FORGED ALUMINUM HUBS WITH STEEL HUBS, AT NO CHARGE.
