Turbocharger: Mounted on the exhaust manifold. Example: Caterpillar C7 Turbocharger enhances engine air intake efficiency.
Piston Ring: Located in the piston grooves. Example: Cummins QSB6.7 Piston Rings maintain cylinder compression.
Water Pump: Front of the engine block. Example: Isuzu 4HK1 Water Pump prevents engine overheating.
Main Relief Valve: Hydraulic control valve block. Example: Daewoo DH60 Relief Valve regulates system pressure.
Float Switch: Fuel or coolant tank. Example: Komatsu PC200 Float Switch monitors fluid levels.
Connecting Rod: Between piston and crankshaft. Example: Yanmar 4TNV94 Con-rod transfers power.
Fuel Injector: Cylinder head assembly. Example: Kubota V2403 Injector ensures precise fuel delivery.
Crankshaft: Engine bottom crankcase. Example: Weichai WD615 Crankshaft converts linear to rotational motion.
Cylinder Block: Main engine structure. Example: Komatsu 6D102 Block houses all internal components.
Oil Pump: Inside the oil pan. Example: Caterpillar 320D Oil Pump ensures lubrication to moving parts.
Device: Komatsu PC200-8 Excavator
Fault: Frequent engine stalling and hydraulic power loss.
Solution: Inspected the 7861-92-4800 float switch and main relief valve. Found pressure leakage in the valve. Replacing with a high-quality aftermarket relief valve and cleaning the fuel system restored full operation.
Maintenance Tip: For Caterpillar C9 engines, change the fuel filters every 500 hours and check the gasket head for any signs of seepage to avoid costly overhauls.
Precision fit for Daewoo DH60 and Komatsu machinery.
Engineered for high-pressure hydraulic systems in construction environments.
Durable construction using premium alloy materials for long service life.
Cost-effective alternative to expensive OEM parts without compromising performance.
