Technical Insights: Component Glossary & Machine Care

10 Engineering Machinery Parts Explained

1. Liner Kit: The set of cylinder liner, piston, and piston rings installed in the Cummins QSB6.7 Cylinder Block of a Cummins Excavator QSB6.7.

2. Gasket Head: A seal placed between the Komatsu 6D120 Cylinder Block and the cylinder head of a Komatsu PC300-7 Excavator.

3. Crankshaft Bearing: Main bearings supporting the crankshaft, located in the Caterpillar 3116 Crankcase of a CAT 320B Excavator.

4. Valve Guide: A sleeve pressed into the Isuzu 4HK1 Cylinder Head, guiding the valve stem in an Isuzu ZAX200 Excavator.

5. Flameout Solenoid: An electrical device that cuts off fuel supply to stop the engine, installed on the Kubota V2203 Fuel Pump of a Kubota KX080 Mini Excavator.

6. Monitor: The main display panel showing vital engine and machine data, typically found in the Yanmar 4TNV98 Cabin of a Yanmar SV100 Tracked Excavator.

7. Radiator: Heat exchanger for cooling the engine coolant, mounted at the front of the Weichai WP10 Engine Bay of a SDLG LG956 Wheel Loader.

8. Main Valve: The core hydraulic control component, installed in the Komatsu PC200 Main Control Valve Body of a Komatsu PC200-8 Excavator.

9. Valve Seat: A surface against which the valve rests, found in the Caterpillar C9 Cylinder Head of a CAT D6T Dozer.

Equipment Fault & Maintenance Guide

Fault Example: Caterpillar 320D Excavator - Engine Oil Pressure Low

Symptom: The engine warning light illuminates, and the gauge shows low oil pressure, particularly when the engine is hot or idling.
Solution:

1. Immediately shut down the engine to prevent damage.

2. Check the oil level; add oil if low.

3. If the oil level is correct, the issue is often a failing Oil Pump or a worn Engine Bearing set (Crankshaft Bearing Set Wholesale Supplier). Replace the Caterpillar 3116 Oil Pump if pressure remains low after inspection.

Essential Maintenance: Engine Cooling System Care

To prevent failures in components like the Thermostat (6222-61-7300), ensure the cooling system is maintained. This involves flushing the radiator and changing the coolant according to the Komatsu 6D120 engine manual, typically every 2000 hours or two years. Always inspect the Radiator and all hoses for leaks and ensure the Fan Cooling belt is tensioned correctly.
