Recall 05V-110: 1998–2003 Optima AH-28, 1998–2003 Optima Opus 29 and 2 more
OPTIMA BUS CORP recall for fuel system, diesel, reported to NHTSA on Mar 24, 2005, covering about 417 vehicles.
The problem
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.
The 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.
The fix
Cummins is conducting the owner notification and remedy for this campaign. Owners may contact cummins at 1-800-343-7357 or optima at 316-779-7700.
