SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE

CERTAIN FREIGHTLINER SCHOOL BUS CHASSIS, HEAVY TRUCKS, AND THOMAS BUILT SCHOOL BUSES MANUFACTURED BETWEEN JULY 2002 AND JULY 3, 2007, EQUIPPED WITH BENDIX SR-7 SPRING BRAKE CONTROL VALVES. THE PARKER SCV BRASS 90 DEGREE SINGLE CHECK VALVES (SCV) WHICH ATTACH TO THE SUPPLY PORT OF A BENDIX SR-7 SPRING BRAKE MODULATING VALVE CAN BREAK APART. PIECES OF THE PARKER SCV CAN BECOME LODGED INSIDE THE SR-7 SPRING BRAKE MODULATING VALVE, POTENTIALLY CAUSING EITHER LEAKAGE OUT OF THE SR-7 VALVE OR PREVENTING AIR FROM PROPERLY EXHAUSTING FROM THE SR-7 VALVE. ALSO, DUE TO A MANUFACTURING DEFECT IN THE INTERNAL RUBBER CHECK VALVE INSIDE THE SR-7 SPRING BRAKE MODULATING VALVES, THE VALVES CAN BECOME DEFORMED AND NOT SEAT PROPERLY.

FUEL SYSTEM, GASOLINE:DELIVERY

ON CERTAIN TRUCKS, A MANUFACTURING ERROR IN THE FUEL-WATER SEPARATOR PREHEATER THERMOSWITCH MAY PREVENT THE FUEL PREHEATER FROM TURNING OFF IF THE IGNITION IS LEFT ON. IF THE IGNITION SWITCH IS LEFT ON WHEN FUEL IS ADDED TO THE FUEL- WATER SEPARATOR AT THE FACTORY OR DURING A FILTER ELEMENT CHANGE, A SMALL FLAME MAY OCCUR INSIDE THE FILTER COVER.

TRAILER HITCHES:FIFTH WHEEL ASSEMBLY

ON CERTAIN TRUCK-TRACTORS EQUIPPED WITH HOLLAND SIMPLEX SE OR SE II FIFTH WHEELS, THE LATCH LEVER PIVOT BOLT ASSEMBLY MAY HAVE BEEN OVER-TIGHTENED WHICH COULD DISTORT THE PIVOT BOLT SPACER SLEEVE. CORROSION OR CONTAMINATES IN THE PIVOT MAY CAUSE IT TO BIND AND PREVENT THE FIFTH WHEEL JAW FROM LATCHING SECURELY AROUND THE TRAILER KING PIN.

STEERING:GEAR BOX:SHAFT SECTOR

ON CERTAIN TRUCKS EQUIPPED WITH TRW STEERING GEARS, MODELS TAS85 AND RCS85, THESE STEERING GEARS CONTAIN POTENTIALLY DEFECTIVE SECTOR SHAFTS WITH AN INCORRECT GEAR TOOTH WHICH MAY INTERFERE WITH THE RACK-PISTON TEETH, RESULTING IN A STICK OR BIND CONDITION.

THE MOLDED VALVE BODY HAS AN INCORRECT CORE PIN IN THE INJECTION MOLD CAUSING THE VALVE BODY TO BE OVERSIZED IN THE DOUBLE CHECK VALVE AREA. THIS CONDITION CAN ALLOW THE RUBBER DOUBLE CHECK VALVE TO BECOME LODGED IN THE BODY OPENING UNDER CERTAIN CIRCUMSTANCES.
