Technical Terms & Installation Guide

Cummins QSB6.7 Turbocharger: Located on the exhaust manifold. Used in Hyundai R210-9 excavators to increase engine efficiency.
Komatsu PC200-8 Main Relief Valve: Installed in the control valve bank. Regulates system pressure to prevent hydraulic overload.
Caterpillar C7 Fuel Injector: Located in the cylinder head. Delivers pressurized fuel into the combustion chamber of Cat 325D excavators.
Isuzu 4HK1 Water Pump: Mounted at the front of the engine block. Circulates coolant through the radiator of Hitachi ZX200-3.
Kubota V2403 Piston: Located inside the cylinder block. Compresses gas to create power in Bobcat S185 skid steers.
Yanmar 4TNV98 Starter Motor: Attached to the flywheel housing. Initiates engine rotation for Gehl V270 loaders.
Weichai WD10 Oil Pump: Positioned in the oil pan area. Provides lubrication for SDLG LG956L wheel loaders.
Komatsu D65 Dozer Crankshaft: The central rotating shaft of the engine. Converts linear piston motion into rotation.
Caterpillar 320D Monitor Panel: Installed in the operator cab. Displays engine health and diagnostic codes.
Isuzu 6WG1 Gasket Kit: Placed between engine components. Prevents leaks in Sany SY485H heavy excavators.

Maintenance & Troubleshooting

Fault Case: Komatsu PC200-8 Hydraulic System Overheating

Symptom: The excavator loses power and speed after 2 hours of work. The hydraulic oil temperature alarm triggers.

Solution: 1. Check the Hydraulic Oil Cooler for debris. 2. Inspect the Main Control Valve (Ref: 24036R76F8 type) for internal leakage. 3. Test the Float Switch (7861-92-4800) for proper fluid level monitoring. In this case, replacing the clogged oil cooler and a worn relief valve restored performance.

Maintenance Tips for Excavators:

Change engine oil and filters every 250-500 hours depending on the model (e.g., Cat 320D).
Inspect the fan belt tension daily to ensure proper cooling.
Always use high-quality fuel filters to protect injectors like the Isuzu 4HK1.
