Product Description

This is a dedicated swing motor assembly for the Komatsu PC75-3 excavator. It features an integrated valve distribution structure, perfectly matching the swing hydraulic system of a 7-ton mini excavator. Pipe interfaces and flange mounting holes allow for direct replacement without modification.

1. Utilizes a high-precision plunger and distribution plate friction pair with surface heat treatment for enhanced resistance to wear and impurities. Suitable for high-frequency swing operations in earthmoving, crushing, and landscaping. An integrated buffer overflow valve group effectively buffers start-stop impacts, preventing swing vibration, head swing, and jamming.

2. Precisely calibrated swing brake pressure ensures a secure stop and prevents slippage on slopes. Equipped with a complete set of high and low temperature resistant oil seals, it prevents oil leakage and internal leakage during prolonged continuous operation, eliminating weak swing and slow speed malfunctions.

3. Thickened cast steel housing; internal plungers and cylinders are made with wear-resistant alloy technology, preventing wear and pressure leakage during long-term heavy-load swing operations. Built-in double buffer overflow valves ensure smooth start-stop, reduce vehicle impact, and extend the life of all hydraulic components.
