Technical Insight: Engine Component Nomenclature

Understanding where and how these parts function is crucial for proper maintenance and ordering:

• Flameout Solenoid: Installed on the fuel pump to control fuel flow and shut down the engine. E.g., Cummins B3.9-C Flameout Solenoid.

• Crankshaft Bearing: Installed within the Cylinder Block, supporting the main crankshaft. E.g., Komatsu 6D102 Crankshaft Bearing.

• Valve Guide: Press-fitted into the Cylinder Head, guiding the valve stem movement. E.g., Caterpillar 3116 Valve Guide.

• Water Pump: Mounted externally on the engine block, circulating coolant. E.g., Isuzu 6BG1 Water Pump.

• Piston Ring: Located in grooves on the Piston, sealing the combustion chamber. E.g., Yanmar 4TNV98 Piston Ring.

• Turbocharger: Bolted to the exhaust manifold, forcing compressed air into the engine. E.g., Weichai WP12 Turbocharger.

• Thrust Washer: Located on either side of a main bearing journal, controlling crankshaft end play. E.g., Kubota D902 Thrust Washer.

• Gasket Head: Placed between the Cylinder Block and Cylinder Head, sealing the combustion chamber. E.g., Komatsu 4D105 Gasket Head.

• Main Valve: Typically located in the hydraulic pump or control valve bank, controlling fluid flow. E.g., Caterpillar 330D Main Valve Spool.

• Accelerator Motor: Positioned near the throttle body or fuel pump on electronic engines. E.g., Isuzu 4LE1 Accelerator Motor.

Extensive Model Coverage for Global Machinery

We cover a vast array of engine models used in excavators and construction equipment globally. Whether you are searching for Mitsubishi 4D34 overhaul parts or Volvo D12D engine gasket sets, our inventory ensures you find the exact components you need.

Product Details and Global Logistics (Part No. 3G-2720, 3G2720)

Our commitment extends beyond manufacturing to secure and reliable delivery worldwide. We adhere to strict quality controls to guarantee product excellence, including every Komatsu engine gasket kit and Caterpillar S6K cylinder head we ship.

Technical Tip: Engine Fault Diagnosis and Maintenance

Fault Scenario: CUMMINS QSB6.7 Engine Overheating.

Possible Cause: Failure of the Water Pump or Radiator Clogging. This leads to inadequate coolant circulation and temperature regulation, causing the engine to exceed safe operating limits.

Processing Scheme: Inspect the thermostat function and coolant level. If the issue persists, replace the water pump assembly using a certified Cummins QSB6.7 water pump replacement. Flush the radiator system thoroughly.

Preventative Maintenance: Implement a schedule to check coolant quality and concentration every 500 hours. Replace the coolant and inspect all hoses/belts (including the Cummins B5.9-C belt replacement) annually to prevent overheating and maximize the life of components like the cylinder block and cylinder head.
