22851149 24V 12T Starter Motor

Internal winding aging and component wear cause torque attenuation, leading to slow cold start or even engine ignition failure, which directly hinders the normal operation of the excavator and requires immediate replacement.

Worn drive gears or loose internal parts result in jamming, jitter or abnormal noise during motor operation. Delayed replacement may cause damage to the engine flywheel ring gear and secondary faults.

Sealing failure leads to dust and water intrusion, or circuit aging causes short circuit, resulting in motor burnout and complete loss of starting function, which causes the whole machine to shut down and stop work, requiring urgent replacement.

As a core wearing part of the starting system, the motor has potential aging problems after long-term use. Synchronous replacement during overhaul or maintenance avoids sudden faults and ensures stable equipment operation.
