Technical Glossary: Essential Construction Parts

Understanding your engine components is vital for effective maintenance. Here are 10 key parts we supply:

• 1. Piston Ring: Seals the combustion chamber; installed in the piston grooves. Example: Komatsu PC200-8 6D107 Piston Ring.

• 2. Thrust Washer: Limits the axial movement of the crankshaft; installed at the main bearing saddle. Example: Caterpillar D8T C15 Thrust Washer.

• 3. Water Pump: Circulates coolant through the engine block and radiator; externally mounted on the engine. Example: Kubota U35-4 V2403 Water Pump.

• 4. Flameout Solenoid: Cuts off fuel supply to stop the engine; mounted on the fuel injection pump. Example: Isuzu FRR 6BG1 Flameout Solenoid.

• 5. Valve Guide: Guides the vertical movement of the engine valve; pressed into the cylinder head. Example: Yanmar ViO35-6 4TNV88 Valve Guide.

• 6. Pressure Switch: Monitors system pressure (e.g., oil or hydraulic); typically installed in the engine block or hydraulic manifold. Example: Cummins QSM11 Pressure Switch.

• 7. Nozzle (Injector): Sprays fuel into the combustion chamber; installed in the cylinder head. Example: Weichai WP12 Engine Injector.

• 8. Crankshaft: Converts the piston's linear motion into rotational motion; housed in the engine block. Example: Komatsu PC300-7 6D114 Crankshaft.

• 9. Cylinder Head: Seals the top of the cylinder and contains the valves and spark/glow plugs; bolted to the cylinder block. Example: Caterpillar 320D C6 Cylinder Head.

• 10. Accelerator Motor: Controls the throttle position on electronic engines; typically mounted near the fuel pump or engine. Example: Isuzu 4BG1 Excavator Accelerator Motor.

Engine Model Coverage We Provide

We provide parts for an extensive range of popular engine models, ensuring you find the right component for your equipment, whether it's the Cummins QSB6.7 or the Isuzu 6WG1.

Maintenance Spotlight: Cummins QSB6.7 Engine

Troubleshooting: High Engine Oil Consumption

A common issue in the Cummins QSB6.7 Engine in models like the Komatsu PC200-8 Excavator is unusually high oil consumption. Often, this is caused by worn Piston Rings or compromised Valve Guide seals.

Solution: Inspect the turbocharger seals and PCV system first. If these are clear, a compression test is needed. If compression is low, replacing the Liner Kit and Piston Rings with high-quality alternatives from Honour Time Machinery is essential to restore proper cylinder sealing.

General Engine Maintenance Tips:

• Always use the correct viscosity and grade of engine oil recommended by the OEM.

• Change the Oil Pump and filter at specified intervals to ensure consistent pressure and clean lubrication.

• Periodically inspect and replace the Gasket Head and Overhaul Kit components to prevent leaks and maintain seal integrity.

• Monitor the engine's coolant temperature to prevent overheating, which can damage the Cylinder Head and Cylinder Block.
