Cummins QSB6.7 Turbocharger: Installed on the exhaust manifold to increase engine intake air density. Used in Hyundai R210 excavators.
Komatsu PC200-8 Main Valve: Core hydraulic control unit located in the center of the hydraulic system for flow distribution.
Caterpillar C7 Fuel Injector: Precision component in the cylinder head that sprays atomized fuel for combustion in CAT 325D.
Isuzu 6HK1 Water Pump: Mounted on the front of the engine block to circulate coolant through the radiator.
Yanmar 4TNV98 Piston Ring: Sealing rings fitted on the piston to maintain compression and control oil consumption.
Kubota V2403 Gasket Head: Sealing layer between the cylinder head and block to prevent gas and coolant mixing.
Weichai WD615 Crankshaft: The main rotating part of the engine that converts linear piston motion into rotation.
Komatsu 7861-92-4800 Float Switch: Found in the coolant expansion tank of Komatsu PC300-7 to alert low levels.
Caterpillar 320D Accelerator Motor: Regulates the fuel injection pump throttle position based on operator input.
Isuzu 4JB1 Engine Bearing: Friction-reducing shells installed on the connecting rods and main crankshaft journals.
Problem: The excavator exhibits slow movement and sudden loss of hydraulic pressure when using secondary functions.
Solution: Inspection revealed a clogged Spare Valve 723-46-48100. Replacing the unit with our high-quality alternative restored full system pressure. Maintenance Tip: Always check hydraulic oil purity every 500 hours to prevent valve sticking.
Designed specifically for heavy-duty Excavator or Construction Machinery environments.
Premium alloy construction ensures long-term resistance against high-pressure hydraulic wear.
Plug-and-play compatibility with Komatsu, Caterpillar, and Isuzu mounting points.
Optimized for extreme temperature operation, preventing seal failure in tropical or arctic conditions.
Strictly tested for Zero-Leakage performance before leaving the factory.
