Technical Expertise and Support

10 Essential Engineering Machinery Part Definitions:

1. Connecting Rod Bearing: A replaceable liner installed in the connecting rod to support the crankshaft journal. Komatsu PC300-7 Connecting Rod Bearing.

2. Crankshaft: Converts the linear motion of the piston into rotational motion. Caterpillar 3406 Crankshaft.

3. Thrust Washer: Installed on the crankshaft to control its axial (end-to-end) movement. Cummins QSB6.7 Thrust Washer.

4. Piston Ring Set: Three rings (compression, scraper, oil) installed in the piston grooves for sealing and oil control. Isuzu 6HK1 Piston Ring Set.

5. Oil Pump: Maintains constant oil pressure for lubrication throughout the engine. Yanmar 4TNV88 Oil Pump Mechanism.

6. Cylinder Head Gasket: Seals the combustion process between the engine block and cylinder head. Kubota V2403 Cylinder Head Gasket.

7. Turbocharger: Boosts engine power by forcing compressed air into the combustion chamber. Weichai WP12 Turbocharger.

8. Fuel Injector: Atomizes and sprays fuel into the cylinder or pre-combustion chamber. Komatsu S6D107E Fuel Injector.

9. Water Pump: Circulates coolant through the engine and radiator to regulate temperature. Caterpillar C15 Water Pump.

10. Cylinder Block: The main body of the engine, containing the cylinders (liners). Cummins 6BT Cylinder Block.

Engineering Machinery Fault & Solution:
           Equipment/Model: Komatsu PC200-8 Excavator (4D95 Engine) exhibits excessive white smoke and coolant loss.
           Solution: This strongly suggests a breach of the combustion chamber seal, likely due to a failed Cylinder Head Gasket or a cracked Cylinder Head or Liner (6207-21-2110). Immediate action is required: Perform a cylinder pressure test. If leakage is confirmed, replace the entire Engine Overhaul Gasket Set and inspect the Piston (6202-32-2120) and Liner for thermal damage before reassembly.
