Understanding your construction machinery spare parts is key to effective maintenance. Here are 10 key terms for engine and machine components:
Piston Ring: Installed on the Piston in the Cylinder Block. Komatsu 6D102 Piston Ring prevents combustion gas leakage and controls oil consumption.
Gasket Head: A vital seal between the Cylinder Block and Cylinder Head. Caterpillar C7 Gasket Head maintains combustion chamber integrity.
Flameout Solenoid: Located on the Fuel Pump or near the Fuel Rack. Isuzu 4HK1 Flameout Solenoid cuts off the fuel supply to stop the engine.
Engine Bearing: Installed inside the Crankshaft and Connecting Rods. Yanmar 4TNV98 Engine Bearing supports the crankshaft rotation.
Transmitter: Often a Pressure Transmitter sensor located on the hydraulic system or engine. Cummins QSB6.7 Pressure Transmitter sensor converts physical pressure into an electrical signal.
Valve Seat: Located in the Cylinder Head. Weichai WP6 Valve Seat repair kit seals the intake and exhaust ports during combustion.
Water Pump: Mounted on the front of the Engine Block. Kubota V3307 Water Pump circulates coolant through the engine and radiator.
Turbocharger: Attached to the Exhaust Manifold. Caterpillar C9 Turbocharger increases air intake density for greater power.
Crankshaft: Rotates within the main Engine Bearings. Isuzu 6WG1 Crankshaft converts linear piston motion into rotational power.
Main Valve: Central component within the Hydraulic Control Valve. Komatsu PC200-8 Main Valve assembly directs pressurized fluid to actuators like the Travel Motor.

Fault: Excessive blue smoke and high oil consumption in a Komatsu PC40-7 Excavator Engine.
Solution: This often indicates worn piston rings, cylinder liners, or valve guides. The immediate action is to replace the heavy-duty Piston Ring set and Liner Kit replacement with high-quality components. Utilizing a comprehensive full Gasket Kit during the overhaul ensures all seals are renewed, to resolve engine oil consumption and abnormal performance issues.
Daily Check: Inspect hydraulic fluid levels (Travel Motor oil included) and check the Engine Monitor repair for any abnormal readings.
250-Hour Service: Change engine oil and filter. Inspect the tension and condition of the Engine Belt replacement and check the high-efficiency Radiator fins for blockage.
500-Hour Service: Replace the fuel filter and perform an inspection of the fuel injector Nozzle for proper spray pattern. Check all seals, especially the Gasket Head for engine overhaul integrity.
2000-Hour Overhaul: Deep inspection of the engine core. Consider preventative replacement of the Crankshaft bearing set and main Engine Bearing supplier components to prevent catastrophic failure.
