Applications & Compatibility
These Komatsu genuine replacement parts are essential for maintaining PC200-7, PC220-7, and PC3400-11 excavators in demanding operations. The BLOCK series ensures structural integrity in hydraulic systems, while LEVER components optimize control mechanisms. HOSE assemblies maintain fluid transfer efficiency in:
Mining operations (e.g., coal extraction with PC3400-11)
Road construction (PC200-7 asphalt preparation)
Urban demolition (PC220-7 building dismantling)
Maintenance Tips
Replace hydraulic filters every 500hrs for optimal pump performance
Lubricate lever assemblies bi-weekly in high-dust environments
Inspect BLOCK components quarterly for stress fractures
Troubleshooting
Hydraulic leaks: Check HOSE connections before component replacement
Unresponsive controls: Verify LEVER ASS'Y integrity
Structural vibrations: Inspect BLOCK mounting surfaces
