📚 Heavy Machinery Component Glossary & Applications

• Fuel Injector: Delivers atomized fuel into the engine's combustion chamber. Installed in the Cylinder Head. (Application: Cummins QSB6.7 Engine - Fuel Injector)

• Turbocharger: A forced induction device used to increase an engine's power by forcing compressed air into the combustion chamber. Mounted on the exhaust manifold. (Application: Caterpillar 320D Excavator - C6.4 Engine - Turbocharger)

• Crankshaft Pulley: Drives accessory belts (e.g., for the Water Pump, Alternator). Attached to the front of the Crankshaft. (Application: Isuzu 6HK1 Engine - Crankshaft Pulley)

• Water Pump: A key component of the cooling system, circulating coolant. (Application: Komatsu WA380-6 Wheel Loader - SAA6D107E-1 Engine - Water Pump)

• Rocker Arm: Pivots to push down on the valve stem, opening the valves. Located in the Cylinder Head. (Application: Weichai WP10 Engine - Rocker Arm)

• Connecting Rod Bearing: Provides a wear surface between the Connecting Rod and the Crankshaft. (Application: Kubota V3307 Engine - Connecting Rod Bearing)

• Engine Block: The foundation of the engine, containing the cylinders. (Application: Cummins QSK60 Engine - Engine Block)

• Piston Pin: Connects the Piston to the Connecting Rod. (Application: Yanmar 4TNV94 Engine - Piston Pin)

• Thrust Washer: Used to limit the axial movement of the Crankshaft. (Application: Caterpillar D8T Dozer - C15 Engine - Thrust Washer)

• Oil Cooler: Transfers heat from the engine oil to the coolant or air. (Application: Komatsu PC400-8 Excavator - SAA6D125E-5 Engine - Oil Cooler)

⚠️ Troubleshooting: Diesel Engine Low Oil Pressure

Equipment/Fault: Cummins QSB6.7 Engine (in a Komatsu PC210-10 Excavator) displays critically low oil pressure, especially when the engine is hot.

Probable Cause: A common and serious cause is excessive clearance in the Main Bearings or Connecting Rod Bearings. Wear allows too much oil to escape, reducing pressure in the system. Another possibility is a failing Oil Pump.

Solution: Immediately stop the engine to prevent catastrophic failure. The oil pan must be removed for inspection. Check Main Bearing and Connecting Rod Bearing clearances using Plastigage. If out of specification, replace the worn Bearings and assess the Crankshaft for damage, replacing the Oil Pump as necessary to restore proper lubrication pressure.
