Turbocharger: Installed on the engine exhaust manifold. Example: Caterpillar 320D Excavator with C6.4 engine uses a turbocharger to increase air intake efficiency.
Fuel Injector: Located in the cylinder head. Example: Komatsu PC200-8 with 6D107 engine requires high-pressure common rail injectors for precise fuel delivery.
Main Relief Valve: Found in the hydraulic control valve group. Example: Caterpillar 336D uses ZM2903849 to protect the hydraulic system from overpressure.
Float Switch: Mounted in the fuel or coolant tank. Example: Komatsu PC300-7 uses 7861-92-4800 to monitor fluid levels and prevent dry running.
Cylinder Block: The main structure of the engine. Example: Cummins 6BT5.9 engine block houses the pistons and crankshaft.
Water Pump: Attached to the front of the engine block. Example: Isuzu 4HK1 engine uses a water pump to circulate coolant.
Crankshaft: At the bottom of the engine block. Example: Yanmar 4TNV94 engine crankshaft converts linear piston motion into rotation.
Gasket Kit: Placed between engine components. Example: Kubota V2403 full gasket set prevents oil and coolant leaks.
Solenoid Valve: Often on the fuel pump. Example: Weichai WP10 uses a flameout solenoid to shut down the engine safely.
Liner Kit: Inside the cylinder bores. Example: Caterpillar C15 engine liner kits ensure high compression and durability.
Case Study: Excavator Hydraulic Power Loss
Equipment: Caterpillar 320C Excavator
Issue: The hydraulic system suddenly lost pressure, and the machine moved slowly.
Solution: Inspection revealed the relief valve was stuck. Replacing the unit with ZM2903849 Relief Valve restored system pressure to 35MPa and resolved the failure.
Maintenance Tip: For Komatsu PC200-7, always check the 7861-92-4800 Float Switch during every 500-hour service to ensure the electrical connections are free from corrosion.
Perfect Compatibility: Specifically designed for CATERPILLAR and KOMATSU excavators to ensure seamless installation.
Durable Construction: Made from high-strength alloy steel to withstand extreme construction environments.
Precision Sensing: Part 7861-92-4800 offers highly accurate fluid level detection to prevent engine damage.
OEM Performance: ZM2903849 provides stable pressure relief identical to original equipment standards.
Universal Application: Ideal for excavators, loaders, and various construction machinery engines.
