1999 Orion II problems

What is wrong

On certain transit buses, 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.

Risk

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.

What is wrong

Vehicle description: trucks, school bus and motor home chassis, and transit buses equipped with tie rod assemblies manufactured by trw. The suspect tie rods contain 24-dl model ball sockets. Certain of the tie rod ball-socket bearings have a below-specification case depth and/or hardness, which can lead to premature wear of the socket.

Risk

If this condition occurs, the driver can lose partial control of the right front wheel, possibly resulting in a crash.

Remedy

Dealers will replace the defective ball sockets and/or drag links. Owner notification began may 22, 2001.

What is wrong

Vehicle description: transit buses equipped with vanner 60 series battery equalizers. The equalizer could fail to operate properly and cause malfunction of the battery charging system.

Risk

Without fusing, the equalizer may melt, burn, or smoke, possibly resulting in a fire or a smoke filled bus, thus necessitating a passenger evacuation of the bus. The failure mode can cause operator distraction, and/or possible personal injury.

Remedy

Orion will notify owners to inspect their buses for certain equalizers by the date code. The affected equalizers will be replaced by vanner.
