1985 Neoplan NEOPLAN recalls

AN INDUCTIVE VOLTAGE SPIKE MAY AFFECT THE REAR DOOR TIME DELAY RELAY IN A MANNER WHICH CAUSES THE MAGNETIC BRAKE VALVE TO ENERGIZE. WHEN THIS VALVE IS ENERGIZED THE BUS BRAKES ARE APPLIED. CONSEQUENCE OF DEFECT: IF THIS OCCURS WHEN THE BUS IS IN MOTION, THE BUS WILL BRAKE UNEXPECTEDLY WITHOUT ANY ACTION FROM THE OPERATOR AND MAY CAUSE INJURIES TO ITS OCCUPANTS OR CAUSE AN ACCIDENT.

Remedy

INSTALL A NEW REAR DOOR TIME DELAY RELAY TO PREVENT BRAKES FROM BEING ACTIVATED AT THE WRONG TIME.

SYSTEM:REAR DOOR TIME DELAY RELAY.VEHICLE DESCRIPTION:BUSES WITH PRINTED CIRCUIT BOARDS AND CONTAINING REAR DOOR TIME DELAY RELAY.

THE 25 AMP AUTOMATIC RESET CIRCUIT BREAKER COULD FAIL IN THE CLOSED POSITION.

Consequence

THIS COULD JEOPARDIZE THE CIRCUITRY TO BE PROTECTED BYTHE CIRCUIT BREAKER AND COULD RESULT IN AN ELECTRICAL FIRE.

Remedy

REPLACE CIRCUIT BREAKER.

SYSTEM: ELECTRICAL/CIRCUIT BREAKER.VEHICLE DESCRIPTION: 30, 35, 40, AND 60 FT. TRANSIT BUSES.

THERE MAY BE TIE ROD CLAMP INTERFERENCE WITH THE FRONT SUSPENSION STRUCTURE. ALSO, STEERING WHEEL MAY BECOME STIFF DUE TO NON-PERMANENT LUBE STEERING SHAFT CROSS BEARINGS. CONSEQUENCE OF DEFECT: STEERING COULD BIND OR BECOME HARD RESULTING IN LOSS OF CONTROL AND COULD CAUSE AN ACCIDENT.

Remedy

ASSURE PROPER TIE ROD CLAMP POSITIONING AND INSTALL GREASEABLE CROSS BEARINGS IN THE STEERING SHAFT.

VEHICLE DESCRIPTION: 1981 TO 1984 35' AND 40' TRANSIT BUSES, 1982 TO 1984 ARTICULATED BUSES, AND 1984 AND 1985 TIT'L BUSES.SYSTEM: STEERING, TIE ROD CLAMP.

CHAFING CONDITION MAY OCCUR BETWEEN FRONT AIR BRAKE HOSE AND TIRE. ALSO, RUBBER BRAKE PEDAL COVER MAY BECOME DETACHED FROM METAL PEDAL ASSEMBLY. CONSEQUENCE OF DEFECT: IF THE CHAFING DAMAGES THE AIR BRAKE HOSE TO THE POINT THAT IT LEAKS, EFFECTIVENESS IS DIMINISHED. ALSO IF RUBBER BRAKE PEDAL COVER FALLS OFF, THE DRIVERS FOOT MAY SLIP OFF THE PEDAL WHEN BRAKES ARE BEING APPLIED. IN EITHER CASE AN ACCIDENT MAY OCCUR.

Remedy

ADJUST FRONT BRAKE HOSE POSITIONING AND GLUE THE RUBBER BRAKE PEDAL ON, AS REQUIRED.

VEHICLE DESCRIPTION: 1981 TO 1985 35 AND 40 FT ADB TRANSIT BUSES, 1982 TO 1984ARTICULATED BUSES, AND 1984 AND 1985 LIT'L BUSES. SYSTEM: BRAKES, AIR HOSE

CIRCUIT BREAKERS ARE NOT AT SUFFICIENT RATINGS TO PROTECT HIGH SIDE TOLERANCES, SOME WIRING HARNESSES ARE NOT ADEQUATELY SECURED TO PREVENT CHAFING AND NO PROVISIONS WERE MADE FOR COMPLETE DISCONNECTION OF ALL ELECTRICAL SYSTEMS IN CASE OF AN ELECTRICAL SHORT. CONSEQUENCE OF DEFECT: THE ABOVE COULD RESULT IN A BUS FIRE.

Remedy

ADD AND/OR REPLACE CIRCUIT BREAKER, INSTALL CUT OFF SWITCH AND REROUTE WIRES.

VEHICLE DESCRIPTION: 1981 THRU 1985 35 AND 40 FOOT TRANSIT BUSES, 1982 THRU 1984 ARTICULATED BUSES AND 1984 AND 1985 LITL' BUSES.SYSTEM: ELECTRICAL.
