Cylinder Liner: Installed in the cylinder block (e.g., Komatsu 6D102). It provides a smooth surface for the piston.
Turbocharger: Mounted on the exhaust manifold (e.g., Caterpillar C9). Increases engine power by forcing air into the combustion chamber.
Fuel Injector: Located in the cylinder head (e.g., Isuzu 4HK1). Precise delivery of diesel into the engine.
Main Relief Valve: Found in the hydraulic control valve (e.g., Komatsu PC200). Regulates maximum system pressure.
Crankshaft: At the bottom of the engine block (e.g., Cummins QSB6.7). Converts linear piston motion into rotation.
Water Pump: Front of the engine (e.g., Yanmar 4TNV94). Circulates coolant to prevent overheating.
Piston Ring: Around the piston head (e.g., Kubota D1105). Seals the combustion chamber.
Oil Pump: Inside the oil pan area (e.g., Mitsubishi 6D16). Lubricates all moving engine parts.
Gasket Head: Between block and head (e.g., Hino J08E). Prevents leakage of gas and coolant.
Radiator: Front of the machinery (e.g., Volvo D6E). Dissipates heat from the engine coolant.
Case Study: Hydraulic Power Loss in Komatsu PC200-7
Symptoms: The excavator arm moves slowly and makes a high-pitched squealing sound under load.
Diagnosis: The Main Relief Valve (723-40-50100) was found to have a weakened internal spring, causing pressure to bypass back to the tank prematurely.
Solution: Replacing the faulty unit with our High Quality 7234050100 Replacement restored system pressure to 32.5 MPa, eliminating the noise and restoring full cycle speed.
Maintenance Plan: Inspect hydraulic oil purity every 500 hours. Contaminated oil is the primary cause of relief valve erosion.
Precision Machined: Uses aerospace-grade steel for maximum durability under high pressure.
Direct Fitment: Matches original Komatsu PC series mounting dimensions for easy installation.
Cost-Effective: Premium aftermarket quality at a fraction of the dealer price.
Anti-Corrosion Coating: Finished with a protective layer to withstand harsh construction environments.
Use for Excavator or Construction Machinery: Specifically engineered for rigorous hydraulic cycles.
