BEARING 2U5284 - Caterpillar

Industrial EngineC9.3 (S/N: CS91-UP)Description Of Change: The improved CEM wiring routing addresses the erratic SCR inlet temperature sensor signals to resolve the 3105-3 and 3105-4 faults intermittently tripping due to electromagnetic field interference from spark plug wire.Adaptable To: The 373-5283 Temperature Sensor Gp is intermittently tripping a 3105-3 or 3105-4 fault code error due to current wiring routing. Electromagnetic field interference from spark plug wire in proximity with SCR temperature sensor box is causing erratic temperature reading and high-voltage codes to trip. Table 1 contains the part numbers needed to move the harness.
