ON TROLLEYS AND TRANSIT COACHES EQUIPPED WITH CUMMINS ISB DIESEL ENGINES, THE FUEL LIFT PUMP COULD FAIL IN A MANNER WHICH RESULTS IN ENGINE FUEL STARVATION, WHICH COULD RESULT IN A STALL CONDITION. POTENTIAL LIFT PUMP FAILURE MODES INCLUDE: BRUSH WEAR OUT, BUSHING FAILURE, ROTOR TAB INSERT FAILURE, OR ANY OTHER FAILURE MODE THAT WOULD CAUSE THE FUEL PUMPING ELEMENT TO STOP SPINNING.

Consequence: IF THE FUEL LIFT PUMP PUMPING ELEMENT STOPS SPINNING AND THE FUEL PUMPING VANES STOP IN A LOCATION WHICH BLOCKS FUEL FLOW THROUGH THE LIFT PUMP, THE ENGINE WILL BE STARVED OF FUEL. FUEL STARVATION COULD CAUSE LOW ENGINE POWER, ENGINE MISFIRE, OR ENGINE STALL. PRIOR TO THE ENGINE STALLING, THE OPERATOR COULD EXPERIENCE LOW ENGINE POWER, ENGINE MISFIRE, AND/OR DASH-MOUNTED FAULT LAMP ILLUMINATION.

ON CERTAIN TRANSIT BUSES WITH CUMMINS ISB02 ENGINES, THE HYDRAULIC LINE COMING OFF OF THE POWER STEERING PUMP IS RUBBING ON TOP OF THE AIR GOVERNOR.

ON CERTAIN TRANSIT VEHICLES AND TROLLEYS EQUIPPED WITH CUMMINS ISB-02 DIESEL ENGINES BUILT WITH EMC CONTROLLED FUEL LIFT PUMPS. ERRATIC VOLTAGE SUPPLY TO THE FUEL LIFT PUMP CAUSES PREMATURE ELECTRIC BRUSH WEAR INTERNAL TO THE FUEL LIFT PUMP. THIS PREMATURE WEAR COULD RESULT IN FUEL LIFT PUMP FAILURE AND IN SOME CASES MAY CAUSE AN ENGINE STALL CONDITION.

Consequence: SHOULD THE ENGINE STALL, A VEHICLE CRASH COULD OCCUR.

Remedy: CUMMINS, IN CONJUNCTION WITH OPTIMA BUS, WILL NOTIFY OWNERS AND REPAIR THE ENGINES BY EMC RECALIBRATION AND REPLACEMENT OF THE FUEL LIFT PUMP AT NO CHARGE TO THE CUSTOMER. OWNERS MAY CONTACT CUMMINS ASSISTANCE CENTER AT 1-800-DIESELS OR OPTIMA BUS AT 1-316-779-7700.
