Design Features & Performance Advantages
- CUM B Series / KOMATSU Wheel Loader‑Rated Design: Utilizes robust direct‑drive architecture with 4.5KW output and a 10T drive gear, engineered to deliver strong cranking power for CUM B Series 5.9L diesel engines and KOMATSU WA series wheel loaders equipped with 4B engines.

Durable graphite brushes and a reinforced housing ensure long service life in demanding construction environments.
