Fuel system, other: delivery: fuel pumpReported September 13, 2005 · 167 vehicles affected

What is wrong: 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.
Risk: 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.

Engine and engine cooling: cooling system: radiator assemblyReported August 15, 2005 · 49 vehicles affected

What is wrong: 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.
Risk: 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.
Remedy: 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.
