Engineering Machinery Component Glossary

A quick reference for key heavy equipment engine components and their common applications:

  • Connecting Rod: Connects the piston to the crankshaft, transforming reciprocating motion into rotation. (Used in: Cummins QSB6.7 Connecting Rod on a New Holland T6.175 Tractor)

  • Crankshaft Bearing: Supports the crankshaft within the cylinder block. (Used in: Caterpillar 3406E Crankshaft Bearing in a Cat D8R Dozer)

  • Thrust Washer: Limits the fore and aft movement of the crankshaft. (Used in: Komatsu SAA6D125E Thrust Washer for a Komatsu PC400-7 Excavator)

  • Fuel Pump: Delivers fuel from the tank to the injection system. (Used in: Isuzu 4HK1 Fuel Pump on an Isuzu NPR Truck)

  • Cylinder Head: Sits on top of the cylinder block, forming the combustion chamber. (Used in: Kubota V3307 Cylinder Head in a Kubota SVL95-2S Skid Steer)

  • Piston Ring: Seals the combustion chamber and regulates oil consumption. (Used in: Yanmar 4TNV98 Piston Ring in a Yanmar VIO50 Excavator)

  • Turbocharger: Increases engine power by forcing compressed air into the combustion chamber. (Used in: Weichai WP10 Turbocharger on a Shacman F3000 Dump Truck)

  • Water Pump: Circulates coolant through the engine to prevent overheating. (Used in: Cummins B3.3 Water Pump in a JCB 8085 Excavator)

  • Injector: Delivers atomized fuel into the combustion chamber. (Used in: Caterpillar C9 Injector for a Cat 330D Excavator)

  • Oil Pump: Circulates engine oil under pressure to lubricate moving parts. (Used in: Komatsu 6D105 Oil Pump in a Komatsu GD510R Grader)

Fault Diagnosis: Overheating on a Komatsu PC200-8 Excavator

Equipment & Model: Komatsu PC200-8 Excavator (Engine: Komatsu SAA6D107E-1).

Fault: The engine frequently overheats under heavy load, requiring frequent stops. The coolant level is stable, but the temperature gauge climbs rapidly.

Processing Solution: Start by checking the engine's main cooling system components. The most common cause, assuming the coolant is clean, is a failing Water Pump or a blockage in the radiator.

  • Step 1: Inspect the Komatsu PC200-8 Water Pump for leaks or shaft play, indicating internal impeller corrosion or bearing failure.

  • Step 2: Thoroughly clean the exterior of the radiator fins to ensure proper airflow.

  • Step 3: If the pump and radiator are clear, test the fan clutch engagement. If the fan is not spinning fast enough, it must be replaced.

  • Solution Keyword: Komatsu PC200-8 Water Pump Replacement.
