DEFECT #1 - ENGINE AND ENGINE COOLING:COOLING SYSTEM:RADIATOR ASSEMBLY
Posted on: 2005-08-15
Description
On certain transit buses, there is a possibility that the hydraulic line coming from the radiator fan motor to the cac motor is rubbing on the chassis.
Consequence
This rubbing may cause the hydraulic line to be rubbed through resulting in a leak and a loss of hydraulic fluid. This fluid could ignite if it comes in contact with a hot source.
Corrective Action
Dealers will install a p-clamp on the radiator motor support bracket that holds and secures the hose away from the chassis eliminating the possibility of chaffing. The recall began on august 24, 2005. Owners may contact optima at 1-888-391-1777.

DEFECT #3 - FUEL SYSTEM, DIESEL
Posted on: 2005-03-24
Description
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.
Corrective Action
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.
