Design Features & Performance Advantages
- KOMATSU Bulldozer‑Rated Design: Utilizes robust direct‑drive architecture with 4.5KW output and a 10T drive gear, engineered to deliver strong cranking power for the KOMATSU D41-E bulldozer / crawler tractor. The 10‑tooth drive gear with precision‑cut teeth ensures optimal engagement and minimizes wear under heavy earthmoving equipment operating cycles.
- 24V Electrical System Compatibility: This is a 24‑volt starter — designed for heavy‑duty construction equipment that uses a 24V electrical system. It provides a straightforward, bolt‑on replacement matching the original DENSO / KOMATSU mounting and electrical specifications.
- Premium Materials for Earthmoving Duty: The motor incorporates high‑purity copper windings and Class F insulation, offering excellent heat resistance and preventing failure under the frequent start‑stop cycles typical of bulldozer operation. Durable graphite brushes and a reinforced housing ensure long service life in demanding earthmoving environments.
