Construction Machinery Parts Glossary (Long-Tail SEO Focus)
Understanding key components for reliable maintenance and repair.
1. Cylinder Liner (Liner)
A replaceable sleeve installed in the Engine Block. It forms the combustion chamber. Example: Cummins QSB6.7 Cylinder Liner.
2. Piston Ring
Sealing rings installed on the Piston to seal the combustion chamber and manage oil consumption. Example: Komatsu 6D107E-1 Piston Ring Set.
3. Crankshaft
The main rotating component that converts piston reciprocating motion into rotational motion, located in the Engine Block. Example: Caterpillar C9 Crankshaft.
4. Turbocharger
A forced induction device that increases power by forcing extra air into the combustion chamber, mounted on the Exhaust Manifold. Example: Isuzu 4BG1 Turbocharger.
5. Water Pump
Circulates coolant through the engine cooling system, mounted on the Engine Block/Front Cover. Example: Kubota V2403 Water Pump.
6. Oil Pump
Circulates lubricating oil under pressure to bearings, pistons, and camshafts, located in the Oil Sump/Engine Block. Example: Yanmar 3TNV88 Oil Pump.
7. Hydraulic Main Pump
The primary component converting mechanical power into hydraulic flow, located in the Main Frame/Hydraulic System. Example: Komatsu PC200-8 Hydraulic Main Pump K3V112.
8. Engine Wiring Harness
The network of wires that transmits electrical signals and power between the ECU, sensors, and actuators on the Engine/ECU. Example: Caterpillar 336D Engine Wiring Harness.
9. Pressure Sensor
Measures fluid or gas pressure in systems like the engine oil or main hydraulic lines, threaded into the Hydraulic Line/Engine Block. Example: Komatsu SK200-8 Oil Pressure Sensor 7861-93-1812.
10. Alternator
Generates electrical power to charge the battery and run the machine's electrical systems, mounted on the Engine. Example: Weichai WD615 Alternator.
Maintenance & Troubleshooting Insight
Failure Scenario: Sudden Hydraulic Power Loss on a Caterpillar 320D
Symptom: A Caterpillar 320D Excavator (Cat C6.4 engine) starts normally, but after a few minutes of operation, the main pump hydraulic pressure drops to zero, making all work movements impossible, although the engine continues to run fine. This often occurs when the hydraulic fluid warms up.
Diagnosis and Solution: This is a classic symptom of a failure in the main pump's control system. The issue is frequently the Proportional Solenoid Valve (e.g., Cat 20R-0131) or the internal Pilot Pump section, which provides control pressure to regulate the main pump's output flow (swash plate angle). When the valve fails electrically, or the pilot pressure is insufficient due to internal pump wear, the main pump "de-strokes" (reduces flow to zero). Solution: First, check the electrical signal and resistance of the Solenoid Valve. If the electrical components are good, the Pilot Pump or internal seals in the main Hydraulic Pump Assembly (K3V140DT) must be inspected and replaced. We supply reliable high-quality Hydraulic Gear Pump Pilot Pump components to resolve this common fault.
