Komatsu PC300-7 Turbocharger: Mounted on the exhaust manifold; increases engine air intake efficiency.
Isuzu 6HK1 Fuel Injector: Installed in the cylinder head; delivers pressurized fuel to the combustion chamber.
Cummins 6CT Crankshaft: Found in the lower engine block; converts linear piston motion into rotation.
Yanmar 4TNV94 Water Pump: Part of the cooling system; circulates coolant to prevent overheating.
Kubota V2203 Glow Plug: Threaded into the cylinder head; assists cold starts in diesel engines.
Weichai WD615 Oil Pump: Located in the oil pan area; ensures lubrication for all moving engine parts.
Volvo EC210 Main Relief Valve: Part of the hydraulic pump; regulates maximum system pressure.
Hitachi EX200-5 Swing Motor: Mounted on the upper structure; allows the excavator to rotate 360 degrees.
Doosan DH220 Final Drive: Located at the crawler tracks; provides torque for vehicle movement.

Technical Support: Troubleshooting & Maintenance

Case Study: High Engine Temperature in Caterpillar 336D

Problem: Overheating under heavy load during summer operation.

Solution: 1. Inspect the radiator for external debris and clean with low-pressure air. 2. Replace the faulty thermostat. 3. Check the Caterpillar Water Pump for leaks. 4. Verify coolant concentration. After replacing the water pump and cleaning the radiator, the engine returned to normal operating temperature.

Maintenance Tip: Always use high-quality Fuel Filters for Isuzu 4HK1 engines every 500 hours to prevent fuel pump failure.
