Component Glossary: Where Engine Parts Work

• Main Bearing: Located in the Engine Block (crankshaft journals). Supports the rotating crankshaft. (Cummins KT38 Engine - Main Bearing Set)

• Fan Hub: Mounted on the Front of the Engine. Supports and rotates the cooling fan. (Komatsu PC200-7 Excavator - Fan Hub)

• Gasket: Located between Fixed Engine Components (e.g., Cylinder Head and Block). Ensures a perfect seal to prevent fluid leakage. (Caterpillar 3066 Engine - Head Gasket)

• Exhaust Valve: Installed in the Cylinder Head. Controls the exit of burnt gases from the cylinder. (Isuzu 6UZ1 Engine - Exhaust Valve)

• Alternator: Mounted externally on the Engine Block/Bracket. Generates electrical power for the vehicle's systems and battery. (Kubota V2607 Engine - Alternator)

• Injection Pump Gear: Part of the Timing Gear Train. Drives the fuel injection pump at the correct timing. (Yanmar 4TNV94 Engine - Injection Pump Gear)

• V-Belt: Wraps around Pulleys on Accessories (e.g., Water Pump, Alternator). Transmits power to run auxiliary components. (Weichai WP7 Engine - V-Belt)

• Tappet Cover: Located on the Side of the Engine Block. Covers the lifters/tappets and prevents oil splash. (Cummins N14 Engine - Tappet Cover)

• Sprocket: Used on the Crankshaft/Camshaft in chain-driven engines. Engages the timing chain. (Caterpillar C4.4 Engine - Timing Sprocket)

• Oil Filter: Attached to the Engine Block/Oil Cooler Housing. Filters contaminants from the engine oil. (Komatsu D61EX-15 Dozer - Engine Oil Filter)

Troubleshooting Guide: Engine Power Loss Diagnosis

Equipment: Caterpillar 140K Motor Grader - Engine Model: Cat C7

Fault Symptom: The Cat C7 engine exhibits a Severe Drop in Power and slow throttle response under load.

Common Causes & Solution:

• Cause 1: Turbocharger Failure. Compressor wheel damage or bearing wear prevents the turbo from producing adequate boost pressure. Solution: Inspect the air compressor wheel and turbine wheel for damage. Replace the entire Turbocharger Unit if significant play or damage is found.

• Cause 2: Fuel Restriction. Clogged fuel filters or a failing Diesel Fuel Pump leading to fuel starvation. Solution: Check fuel pressure. Replace primary and secondary fuel filters. Test or replace the Fuel Pump if pressure is below specification.

• Cause 3: Internal Air Leakage. A leak in the intake system (e.g., charge air cooler hose) or poor sealing around the combustion chamber. Solution: Check all intake piping. For internal leakage, check the Cylinder Liner and piston fitment, as poor compression is a major power killer.
