TWO THROTTLE RETURN SPRING DEFECTS ARE INVOLVED IN THIS RECALL. (1) BUSES EQUIPPED WITH CATERPILLAR ENGINES MAY HAVE A THROTTLE RETURN SPRING THAT BREAKS AND PREVENTS THE THROTTLE FROM RETURNING TO IDLE POSITION WHEN THE DRIVER'S FOOT IS REMOVED FROM THE ACCELERATOR CONTROL; (2) BUSES EQUIPPED WITH CUMMINS VT-225 ENGINES MAY HAVE THE THROTTLE RETURN SPRING CONNECTED TO THE THROTTLE SLAVE CYLINDER INSTEAD OF THE FUEL INJECTION PUMP LEVER. IF FAILURE OCCURS IN THE ACCELERATION CONTROL SYSTEM, THE ENGINE MAY ACCELERATE TO ITS MAXIMUM GOVERNED RPM. CONSEQUENCE OF DEFECT: IN EITHER CASE, THROTTLE CONTROL WILL BE LOST WHICH MAY RESULT IN AN ACCIDENT.

Remedy: A REPAIR KIT CONSISTING OF NEW SPRING, MOUNTING BRACKET AND PROPER REPAIR INSTRUCTIONS WILL BE SHIPPED TO EACH OWNER AT NO CHARGE AND THE OWNER MAY MAKE HIS OWN REPAIRS, OR HAVE A THOMAS DISTRIBUTOR OR A REPUTABLE LOCAL SHOP MAKE THE REPAIRS.

Reported: 1988-05-02 (May 2, 1988) · Model years: 1988

A PRESSURE PROTECTION VALVE WAS OMITTED IN FRONT AIR BRAKE PLUMBING THAT IS REQUIRED BY FMVSS 121.

Reported: 1994-08-01 (August 1, 1994) · Model years: 1992, 1993, 1994

A SUDDEN HYDRAULIC PRESSURE LOSS DURING HARD TURNS RESULTS IN A MOMENTARY LOSS OF POWER STEERING ASSIST. THE PRESSURE LOSS OCCURS WHEN THE HYDRAULICALLY DRIVEN ENGINE COOLING FAN TURNS OFF IN THE TURN.

Consequence: THE DRIVER REACTS TO THE LOSS OF POWER STEERING ASSIST BY OVERSTEERING, WHICH COULD RESULT IN A VEHICLE ACCIDENT.

Remedy: THE HYDRAULIC CONTROL VALVES WILL BE REPLACED WITH VALVES OF A NEW DESIGN. UNTIL SUCH TIME AS PARTS ARE AVAILABLE, OWNERS WILL BE INSTRUCTED TO DISCONNECT THE FAN CUTOFF SWITCH SO THAT HYDRAULICALLY DRIVEN FANS WILL RUN FULL TIME, ELIMINATING THE PRESSURE SPIKE.
