Critical Components for Komatsu Excavators and Wheel Loaders
Maintenance is key to maximizing uptime. We stock a full range of filtration products, including the PC300-7 Fuel Filter (part number 600-311-9121) and PC300-6 Diesel Filter (part number 600-311-8321). For Komatsu WA380-3 , the Oil Water Separator (part number 22U-04-21131) is crucial for engine longevity. Structural and hydraulic integrity is maintained with parts like the PC300-8 Retainer Guide Plate (part number 708-2G-13341) and various high-pressure Hose Assemblies like 207-62-71740 for the Komatsu PC300-8.

We help global clients reduce operational costs without sacrificing machine performance, focusing on delivering the best cost-effective spare parts .
Troubleshooting: Komatsu PC300-8 Hydraulic System Issue
One common issue with the Komatsu PC300-8 excavator is a slow or unresponsive boom/stick due to a faulty Solenoid Valve or contamination. If the machine's movement is sluggish, especially after initial startup, first check the Hydraulic Tank Breather Filter (part number 20Y-60-21470 for the D27 -5 series) and the main Hydraulic Oil Filter Element (part number 207-60-71182). A clogged filter can restrict flow. If filtration is clear, inspect the pilot pressure lines and the main control valve's internal components, including the PC300-8 Spring (part number 708-2G-13152) and PC300-8 Slide Block (part number 708-2G-14120). Replacing faulty pilot hoses or the control valve's internal parts often restores full hydraulic responsiveness. Always use correct Komatsu genuine replacement components or tested high-quality aftermarket equivalents.
Specialized Components and Undercarriage Parts
Beyond standard maintenance, we supply specialized items for various heavy machinery. For hydraulic breakers , we offer parts like the GBF320 Vertical Pin (part number F3201704) and SB121 Check Valve (part number F3205000). For undercarriage maintenance on dozers, we have D27 -5 Final Drive Bolts (part number 09203-12485), D27 -5 Track Assemblies (part number 17M-32-02440), and associated seal kits like the Tension Cylinder Seal (part number 180-30-14220). Furthermore, we can assist you with your requirements for Garrett Turbocharger components and KALMAR parts.
Our inventory also supports other leading equipment. For the Cummins NT855 engine , we provide the correct Seal Ring (part number 409191). For the ZDXLB-DH50/58/8/6.5 Grab Bucket Cylinder Repair Kit for the Janyoung JY640E grab steel machine, we ensure a perfect fit, offering a full range of excavator oil cylinder repair kit options.
