Recall History (6 recalls)
ELECTRICAL SYSTEM:STARTER ASSEMBLY
ON CERTAIN HEAVY DUTY TRUCKS BUILT WITH A CATERPILLAR ENGINE WITH A 4 DEGREE TILT, THE STARTER FIELD-STUD MAY CONTACT THE FRAME RAIL BECAUSE OF VARIATIONS IN THE AIR GAP BETWEEN THE FIELD STUD AND THE FRAME RAIL. SHOULD THE STARTER FIELD STUD CONTACT THE FRAME RAIL, THERE WOULD BE A DIRECT FULL BATTERY SHORT TO THE FRAME (GROUND) WHEN THE STARTER IS IN THE CRANKING MODE.
STEERING:LINKAGES
ON CERTAIN HEAVY DUTY TRUCKS EQUIPPED WITH DANA SPICER E-12021 12,000 LB., E-1202W 12,000 LB., OR E-1002W 10,000 LB. FRONT NON-DRIVE STEER AXLES, THE TAPERED BORE THAT CONNECTS THE DRAG LINK TO THE STEERING WAS MACHINED TOO LARGE. THE CLEARANCE BETWEEN A CORRECTLY SIZED DRAG LINK BALL STUD AND THE OVERSIZED TAPERED BORE IS SUFFICIENTLY GREAT ENOUGH TO ALLOW THE DRAG LINK BALL STUD TO FATIGUE AND BRAKE, OR ALLOW THE CASTLE NUT TO BACK ITSELF OFF AND CAUSE THE DRAG LINK TO DISCONNECT.
ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES
ON CERTAIN HEAVY DUTY TRUCKS EQUIPPED WITH INTERNATIONAL DT530, CUMMINS, OR CATERPILLAR I-6 ENGINES, THE POSITIVE BATTERY CABLE BETWEEN THE BATTERIES AND THE STARTER MAY RUB AGAINST AN ELECTRICAL GROUND CABLE BETWEEN THE STARTER AND FRAME RAIL.
TRAILER HITCHES:FIFTH WHEEL ASSEMBLY
ON CERTAIN VEHICLES EQUIPPED WITH AIR OPERATED FIFTH WHEEL SLIDES AND AN MSVA 7-PACK ACCESSORY CONTROLLER, THE 7-PACK CAN ALLOW WATER TO CONTAMINATE ITS CIRCUIT BOARD. THIS COULD RESULT IN INADVERTENT OPERATION OF THE FIFTH WHEEL SLIDE CONTROL.
ENGINE AND ENGINE COOLING
ON CERTAIN HEAVY DUTY TRUCKS EQUIPPED WITH CATERPILLAR DIESEL ENGINES, THE ENGINE ELECTRICAL GROUND CABLE THAT CONNECTS THE ENGINE BLOCK WITH THE STARTER MAY BE ROUTED IN A WAY THAT COULD CAUSE CHAFING AGAINST THE STARTER'S POSITIVE BATTERY CABLES.
