K3SP36C-1CBR-9002 Main Pump: The Heart of Excavator Hydraulic Performance

When a construction company operating a mixed fleet of TB175, TB175W, LG908, Yc85, and SK75 excavators faced recurring hydraulic pump failures that caused costly downtime, they turned to our K3SP36C-1CBR-9002 Excavator Main Pump as a direct replacement solution. The result was restored full machine functionality across their entire fleet, with significantly improved reliability and operational uptime.

Customer Background

Product Applied: K3SP36C-1CBR-9002 Main Pump

As the core hydraulic component of any excavator, the main pump converts mechanical energy from the engine into hydraulic pressure energy that drives every machine movement. The K3SP36C model is engineered for construction machinery applications requiring reliable, high-performance hydraulic power delivery.

How the K3SP36C Main Pump Works

Key Project Outcomes

• Fleet-Wide Compatibility: The K3SP36C main pump seamlessly matched TB175, TB175W, LG908, Yc85, and SK75 excavator models, simplifying spare parts management across the entire mixed fleet
• Full Functionality Restored: Boom lifting, arm telescoping, bucket operation, machine travel, and upper-body swing movements all returned to optimal performance
• Fuel Efficiency Gains: The variable displacement function automatically reduces pump displacement during light-load operation, cutting fuel consumption during idle and light-duty cycles
• Reduced Downtime: With fast 7-15 day delivery and comprehensive pre-shipment testing, the customer minimized equipment idle time and project delays
