Turbocharger: Mounted on the exhaust manifold. Example: Cummins 6BT Turbocharger improves power in 5-ton loaders.
Crankshaft Bearing: Located inside the cylinder block. Example: Komatsu 6D102 Main Bearing supports the rotating shaft.
Piston Ring: Installed in piston grooves. Example: Caterpillar C7 Piston Ring maintains cylinder compression.
Fuel Injector: Fitted in the cylinder head. Example: Isuzu 6HK1 Injector manages precise fuel atomization.
Water Pump: Front of the engine block. Example: Kubota V2403 Water Pump ensures thermal regulation.
Solenoid Valve: Often on the fuel pump. Example: Yanmar 4TNV94 Solenoid controls engine shutdown.
Cylinder Gasket: Between block and head. Example: Weichai WD615 Head Gasket prevents leakage.
Accelerator Motor: Near the injection pump. Example: Komatsu PC200-8 Throttle Motor controls RPM.
Oil Pump: Lower engine section. Example: Isuzu 4BG1 Oil Pump circulates lubrication.
Liner Sleeve: Inside the block bores. Example: Caterpillar 3306 Cylinder Liner provides wear surface.
Case Study: Komatsu PC200-7 E02 Fault Code
Problem: The excavator experiences sudden loss of power or "User Code E02" appears on the monitor, indicating a PC-EPC system error often caused by a faulty controller 7835-26-1009.
Solution: Check the wiring harness for continuity. If wiring is intact, replace the main computer board with our high-quality replacement. Our 7835-26-1009 is pre-programmed for plug-and-play installation.
Maintenance Plan: For engine longevity (e.g., Isuzu 4HK1), replace the fuel filters every 500 hours and use high-grade 15W-40 oil to prevent piston ring sticking and liner scuffing.
Designed specifically for PC200-7 and PC220-7 excavators using part 7835-26-1009.
High-precision circuit boards resistant to vibration and extreme temperature fluctuations.
Fully compatible with OEM sensors, monitors, and hydraulic solenoid valves.
Factory direct pricing providing a cost-effective alternative to original parts without sacrificing performance.
Comprehensive 6-month warranty on all electronic control units and engine internal components.
