At Tonkee Machinery Co.,Ltd., we understand the critical role that high-quality diesel engine components play in the performance and longevity of your excavators. Whether you're operating a Doosan, Daewoo, or Hitachi model, ensuring your machinery is equipped with reliable starter motors and oil pumps is paramount for optimal operation and minimizing downtime. This guide delves into the specifics of these vital parts, offering clarity on their identification and application.

The starter motor is the unsung hero that brings your excavator to life. A robust starter ensures quick and efficient engine ignition, preventing unnecessary strain on your battery and electrical system. We stock a comprehensive range of starter motors designed to fit various excavator models, ensuring compatibility and peak performance. Identifying the correct part number is crucial for a seamless replacement and sustained operation.
Equally critical are the oil pumps, which are responsible for circulating lubricating oil throughout your engine. Proper lubrication is essential to prevent friction, dissipate heat, and remove contaminants, thereby extending the lifespan of your engine components. From cartridge assemblies to full oil pump GPs, we provide a variety of spare parts to keep your excavator running smoothly. For more general information on the various types of hydraulic pumps used in heavy machinery, you can refer to specialized resources.
