This MITSUBISHI car starter is specially designed for Caterpillar Ag.& Ind. (agricultural and industrial) excavators, precisely compatible with the 3064 and C4.2 series 4.25L diesel engines, covering multiple main models of the 311 series and 312 series. The specific scope of application is as follows, which can fully meet the start-up requirements in different operation scenarios and provide high-reliability solutions for engineering equipment users:
(1) Caterpillar 311 series excavators
311 excavator: Applicable to Caterpillar 311 Caterpillar 3064, 4.25L Dsl. 1993-2004 models. As a classic medium-sized excavator of Caterpillar, the 311 model is widely used in municipal infrastructure and agricultural reclamation operations. The 4.25L diesel engine has high requirements for the weather resistance of the starting system. This starter is designed with a 24V voltage, which is compatible with the dual-battery power supply system of the model. Even in winter farmland operations at -30 ℃, it can ensure smooth cold start. The IP65 protection grade can effectively prevent mud, water and dust from entering the field and avoid rusting of the internal components of the starter. The 50A current output can easily drive high compression ratio diesel engines, reducing operation delays caused by weak starting power and perfectly meeting the demand for "rushing the schedule" in agricultural seasonal operations.
311B excavator: Compatible with Caterpillar 311B Caterpillar 3064, 4.25L Dsl. 1998-2002 models. The 311B model is mainly designed for auxiliary operations in mines and often faces extreme environments with high vibration and high dust. Therefore, it has higher requirements for the shock resistance and sealing performance of the starting system. The anti-vibration design of the V2 technical standard of the starter can withstand the ground resonance effect after mine blasting operations and prevent the loosening of internal components. The fully sealed housing can prevent mine dust from invading the commutator, reduce carbon brush wear and extend the maintenance cycle. The internal regulator of IR can cope with voltage fluctuations in the mine power grid, ensuring a stable start-up process and preventing damage to the starter due to voltage surges.
311C excavator: Applicable to Caterpillar 311C Caterpillar 3064, 4.25L Dsl. 2002-2008 models. The 311C model has optimized the power of the hydraulic system, resulting in a greater electrical load during startup. The coordinated output of 24V voltage and 50A current of this starter can drive the engine while avoiding interference with the power supply of the hydraulic system. The EF electronic feedback function can monitor the temperature and current changes of the starter in real time, and warn of potential faults through the excavator's instrument panel, facilitating operators to stop the machine in time for maintenance and reducing component damage caused by "operating while faulty", which is in line with the principle of "safety first" in mining operations.
311D excavator: Compatible with Caterpillar 311D Caterpillar C4.2259ci, 4.25L Dsl.2005 - models. The 311D model is equipped with an upgraded C4.2 diesel engine, which has higher requirements for the adaptation accuracy of the starting system. The starter, through targeted gear parameter optimization, perfectly matches the flywheel ring specifications of the C4.2 engine, avoiding abnormal meshing noise and excessive wear. Meanwhile, in response to the increased compression ratio after the engine upgrade, the torque output of the starter has been precisely tuned to ensure efficient starting without increasing energy consumption, fully meeting the performance requirements of the new generation of diesel engines.
