Turbocharger: Installed on the engine exhaust manifold to increase air intake. Example: Caterpillar 320D (C6.4 Engine) Turbocharger.
Fuel Injector: Precision component in the cylinder head for fuel atomization. Example: Isuzu 4HK1 (ZX200-3) Common Rail Injector.
Water Pump: Circulates coolant throughout the engine block. Example: Komatsu PC200-7 (6D102) Water Pump.
Main Relief Valve: Regulates maximum hydraulic pressure in the main pump. Example: Doosan DH220-5 Main Valve.
Crankshaft: Converts linear piston motion into rotation. Example: Cummins 6BT5.9 Forged Crankshaft.
Alternator: Provides electrical power and charges batteries. Example: Yanmar 4TNV94 12V Alternator.
Oil Cooler: Removes heat from the engine oil. Example: Kubota V2203 Oil Cooler Core.
Thermostat: Controls engine operating temperature. Example: Weichai WP10 Engine Thermostat.
Hydraulic Pump: The heart of the machine's movement. Example: Caterpillar 330C K3V140 Pump.
Float Switch: Detects coolant or fuel levels. Example: Komatsu PC200-8 7861-92-4800 Switch.
Fault Symptom: The excavator exhibits slow movement and lacks digging power when the oil temperature rises.
Diagnosis: Testing revealed that the main relief pressure was only 220 bar (standard is 330-350 bar). The internal spring of the 14513267 Main Relief Valve was fatigued.
Solution: Replaced the old valve with our high-quality aftermarket 14513267 valve. System pressure restored to 345 bar, and machine power returned to normal.
For Komatsu PC200-8 operators, ensure the 7861-92-4800 Float Switch is cleaned every 1000 hours to prevent false "Low Coolant" alarms caused by sediment buildup in the radiator tank.
1. Precision Casting: Engineered for DH220-5-7 Excavator high-pressure environments.
2. Durable Seals: Uses high-temperature resistant O-rings for 14513267 valves.
3. Plug and Play: 7861-92-4800 features OEM-standard electrical connectors.
4. Performance Tested: Every main valve is pressure-tested before shipping.
5. Versatile Application: Suitable for various construction machinery and heavy-duty diesel engines.
