1. Piston Ring: Installed in the Piston Grooves. CUMMINS QSB6.7 Piston Ring is essential for sealing the combustion chamber and regulating oil.
2. Liner Kit: The cylinder sleeve, installed inside the Cylinder Block. Komatsu 6D102 Liner Kit forms the working surface for the piston.
3. Crankshaft Bearing (Main Bearing): Installed in the Cylinder Block Main Bearing Bore. Caterpillar C7 Main Bearing supports the rotation of the crankshaft.
4. Gasket Head (Cylinder Head Gasket): Installed between the Cylinder Head and Cylinder Block. ISUZU 4HK1 Gasket Head prevents leakage of coolant and combustion gas.
5. Valve Guide: Inserted into the Cylinder Head. Yanmar 4TNV98 Valve Guide guides the movement of the engine valves.
6. Turbocharger: Mounted on the Exhaust Manifold. Weichai WP10 Turbocharger uses exhaust gas to compress intake air, boosting power.
7. Flameout Solenoid: Typically mounted on the Fuel Injection Pump or fuel shut-off system. Komatsu PC200-8 Flameout Solenoid controls the fuel supply to stop the engine.
8. Water Pump: Mounted on the Front of the Engine Block, driven by a belt. Caterpillar 320D Water Pump circulates coolant through the engine and radiator.
9. Accelerator Motor: Usually located near the Throttle Body or Governor. Isuzu ZX330 Accelerator Motor controls engine RPM in electronic controls.
10. Valve Seat: Pressed into the Cylinder Head Intake/Exhaust Ports. CUMMINS B3.9-C Valve Seat provides a sealing surface for the valve face.

Symptom: A CUMMINS QSM11-C engine (often used in Komatsu WA500 wheel loaders) experiences rapid oil consumption and blue smoke from the exhaust, indicating oil bypass into the combustion chamber (often through worn Piston Rings).
Solution: A complete engine top-end overhaul, including replacing all QSM11-C Piston Ring Sets (P/N 3802919 equivalent), inspection/replacement of the Cylinder Liner Kits, and checking the valve seals. Our high-quality replacement Piston Rings restore cylinder sealing integrity and effectively resolve the oil consumption issue, extending engine life and efficiency.
Oil Analysis & Filter Change: Regularly conduct oil analysis and change engine oil/filters according to the manufacturer's specified intervals (e.g., every 250-500 hours) to detect early signs of wear and prevent contamination.
Coolant System Check: Annually inspect and flush the cooling system, checking for leaks in the Radiator and integrity of the Water Pump and hoses to prevent engine overheating.
Turbocharger Inspection: Check the Turbocharger shaft for excessive play every 1000 hours to ensure proper function and prevent foreign object damage.
