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.
Our commitment to quality ensures that every product, from a simple **PC300-7 O-Ring** (part number 07000-B2012) to a complex **PC300-7 Valve Assembly** (part number 20Y-60-311131), meets stringent performance standards. 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.
