Technical Glossary: 10 Engine Components and Equipment Use

• Cylinder Liner: The bore where the piston travels. Example: Cummins NT855 Generator Cylinder Liner 3055099.

• Con Rod Bearing: Fitted in the big end of the connecting rod. Example: Caterpillar C7 Motor Grader Con Rod Bearing.

• Turbocharger: Increases power by utilizing exhaust gas energy. Example: Komatsu SAA6D107E-1 Excavator Turbocharger.

• Oil Pump: Supplies pressurized lubricating oil. Example: Isuzu 4HK1 Truck Oil Pump.

• Injector: Delivers atomized fuel for combustion. Example: Kubota V2403 Tractor Injector.

• Water Pump: Circulates coolant. Example: Yanmar 6AYM Marine Engine Water Pump.

• Crankshaft: Converts piston linear motion to rotation. Example: Weichai WD615 Truck Crankshaft.

• Piston Ring: Seals the combustion chamber and controls oil consumption. Example: Cummins NT855 Piston Ring Set.

• Thrust Washer: Manages crankshaft axial play. Example: Caterpillar 3412 Generator Thrust Washer.

• Overhaul Gasket Kit: Contains all necessary seals for a full engine rebuild. Example: Komatsu SAA6D125E-5 Overhaul Gasket Kit.

Common Engine Fault: Diagnosis and Reliable Solution

Fault: A Caterpillar D6R Bulldozer with a Caterpillar 3306 Engine exhibits excessive blue smoke and high oil consumption after 5,000 hours of operation.

Resolution: Blue smoke and high oil consumption strongly indicate oil is burning in the combustion chamber, usually due to worn components.

1. Piston Ring Wear: The piston rings (compression and oil control rings) are worn or stuck, failing to scrape oil from the cylinder liner walls.

2. Cylinder Liner Wear: Excessive wear in the cylinder liner bore (like the 3055099) creates a gap that the rings cannot seal, allowing oil to pass.

3. Valve Stem Seals: Worn valve stem seals can allow oil to leak down the valve guides into the combustion area.
