Comprehensive Komatsu Equipment Services

From excavators and wheel loaders to dozers and haul trucks, we service all Komatsu models with accuracy and care. Our goal is to restore full performance, efficiency, and reliability—no matter the challenge.

Expert Diagnostics: We use Komatsu diagnostic software and service tools (like KOMTRAX and KDPF systems) to quickly identify electrical, hydraulic, and mechanical issues. Our precise troubleshooting process ensures fast, targeted repairs and minimal downtime for your Komatsu excavators, loaders, and dozers.

Engine Repair & Rebuilds: Our technicians specialize in Komatsu diesel engine repair and complete rebuilds. From injector and turbocharger replacements to full engine overhauls, we use OEM-grade Komatsu components and follow factory specifications to guarantee long-term reliability and peak performance.
