Engineering Parts Definitions
1. Turbocharger: Found on Cummins QSB6.7, increases engine power by forcing air into combustion chamber.
2. Crankshaft: Main rotating part of Isuzu 6HK1 engine, converts reciprocating motion to rotation.
3. Fuel Injector: Used in Caterpillar C7 engines for precise fuel atomization.
4. Water Pump: Maintains cooling in Komatsu 6D102 engines to prevent overheating.
5. Piston Ring: Seals the combustion chamber in Yanmar 4TNV98 engines.
6. Cylinder Head: Top covering of the engine block in Kubota V2403 engines.
7. Main Bearing: Supports the crankshaft in Weichai WD10 engines.
8. Oil Pump: Circulates lubricant in Volvo D7E engines for wear protection.
9. Alternator: Charges batteries and powers electrics in Hino J08E excavators.
10. Hydraulic Pump: The heart of Komatsu PC200-8 hydraulic systems.
Technical Support: Troubleshooting and Maintenance
Fault Solution: Hydraulic System Pressure Drop
Device: Caterpillar 320D Excavator
Symptoms: Slow movement, weak lifting force.
Solution: Check the Pressure Relief Valve. If the internal spring is worn or the seal is broken (refer to part 3G-2720), pressure will bypass the circuit. Replace with High Quality Replacement Relief Valve and change the Hydraulic Filter (07069-25400) to ensure clean oil flow.
Preventive Maintenance Tips
Change engine oil and filters every 250-500 hours depending on workload. For Cummins QSB6.7 engines, always use high-grade Fuel Filters and Oil Pumps to extend engine life and maintain fuel efficiency.
