Terminology for Construction Machinery Parts

  1. Turbocharger (CUMMINS QSB6.7): Installed on the exhaust manifold to increase engine air intake.

  2. Floating Switch (KOMATSU PC200-8): Located in the fuel or coolant tank to monitor liquid levels.

  3. Fuel Injector (CATERPILLAR 320D): Mounted in the cylinder head to spray fuel into the combustion chamber.

  4. Main Relief Valve (KOBELCO SK210-8): Installed on the main control valve to regulate system pressure.

  5. Piston Ring (ISUZU 4HK1): Fitted on the piston to seal the combustion chamber and regulate oil.

  6. Water Pump (YANMAR 4TNV98): Attached to the front of the engine block to circulate coolant.

  7. Crankshaft (KUBOTA V2403): The central component of the engine that converts linear motion to rotation.

  8. Thermostat (WEICHAI WP10): Located in the water outlet pipe to control engine temperature.

  9. Glow Plug (ISUZU 4JB1): Screwed into the cylinder head to assist cold starts.

  10. Oil Cooler (KOMATSU D155): Installed on the side of the engine to maintain oil viscosity.

Troubleshooting: Hydraulic System Weakness in KOBELCO SK75

Problem: The excavator experiences slow boom lifting and weak swinging when the oil temperature rises.

Solution: First, check the K3SP36C Pilot Pump pressure. If the pilot pressure is below 3.5MPa, it cannot fully open the main control valve. Replace the worn gear pump with our high-quality replacement to restore hydraulic speed.

Maintenance Tip: For Caterpillar E308 engines, change the hydraulic oil filter every 500 hours to prevent metal particles from damaging the pilot pump internal gears.
