6240-61-1103 Pump assembly Komatsu bulldozer spare parts

The Komatsu 6240-61-1103 pump assembly is a core component of the Komatsu bulldozer hydraulic system. Manufactured strictly according to Komatsu’s original dimensions, precision, and process standards, it is suitable for heavy-duty, high-temperature, and high-vibration operating conditions. It provides stable hydraulic power to the bulldozer’s working device, steering, and braking systems, and is a high-quality replacement part for equipment maintenance, overhaul, and repair.

The 6240-61-1103 pump assembly utilizes a high-precision plunger/gear structure and wear-resistant alloy materials. Internal parts undergo precision grinding and matching, resulting in high volumetric efficiency and stable output pressure, meeting the continuous high-intensity operation requirements of bulldozers. The pump body features high strength and excellent sealing, effectively preventing internal leakage, abnormal noise, insufficient pressure, and other malfunctions, extending the service life of the hydraulic system. All mounting interfaces, flanges, and shaft diameters are consistent with the original factory specifications, ensuring precise assembly, reliable positioning, and perfect matching with hydraulic lines and control valves.

This product uses a Komatsu original factory matching structure, which is wear-resistant, durable, impact-resistant, and highly resistant to pollution, making it suitable for harsh working conditions such as mining, earthmoving, and infrastructure construction. Installation is simple; it directly replaces original factory parts, requiring no modification or adjustment, significantly reducing maintenance time, minimizing equipment downtime losses, and improving overall machine operating efficiency and stability.
