Turbocharger: Installed on the engine exhaust manifold. Example: Caterpillar 320D uses a turbo to increase power.
Fuel Injector: Located in the cylinder head. Example: Isuzu 4HK1 engine requires precise injectors for fuel delivery.
Water Pump: Mounted on the front of the block. Example: Komatsu PC200-8 water pump ensures engine cooling.
Main Bearing: Supports the crankshaft in the block. Example: Cummins 6BT main bearings reduce friction.
Thermostat: Installed in the coolant housing. Example: Yanmar 4TNV94 thermostat regulates operating temperature.
Oil Pump: Inside the oil pan area. Example: Kubota V2403 oil pump maintains lubrication pressure.
Piston: Moves inside the cylinder liner. Example: Weichai WD10 high-strength pistons for heavy loading.
Solenoid: On the fuel pump or starter. Example: Caterpillar C7 flameout solenoid for safety shutoff.
Radiator: Front of the machine cooling system. Example: Komatsu PC300-7 radiator for heat dissipation.
Gasket Head: Between cylinder head and block. Example: Isuzu 6HK1 head gasket prevents leaks.
Equipment: Komatsu PC200-7 Excavator (Engine: 6D102)
Problem: The machine experienced intermittent engine speed fluctuations and failed to respond to throttle input. Fault code indicated a throttle motor error.
Solution: Replaced the faulty unit with our 7861-92-4800 level switch and checked the Hyundai 21EN-32260 style throttle motor harness. After installing the high-quality replacement motor, the throttle response returned to factory standards. We recommend cleaning the cooling system every 1000 hours to prevent overheating.
Precision Fit: Designed for Hyundai and Komatsu excavators to ensure seamless installation.
High Durability: Built to withstand harsh construction environments and extreme temperatures.
Standard Compliance: Manufactured according to international ISO standards for engine components.
Reliable Performance: Resolves abnormal throttle behavior and engine communication faults.
Versatile Use: Ideal for excavators, loaders, and various construction machinery applications.
