Product Description
Compatibility & Application
All parts are 100% compatible with Yuchai Joint Power YC6K12 6-cylinder turbocharged diesel engine (12.0L displacement, 380-420 HP). Designed for heavy-duty trucks, construction machinery and long-haul trailers, our parts perfectly match the engine’s high-load and long-working-hour demands, meeting routine maintenance, overhaul and emergency repair needs.
Parts Coverage
Our parts fully cover core systems: power core (cylinder block K1100-1002000, piston-rod, camshaft), fuel & air (injection pump, turbocharger, intake/exhaust manifold), lubrication & cooling (oil pump, filter, water pump), and electrical & control (starter, alternator, ECU). EWP-marked easy-wear parts (gaskets, oil seals, piston rings) are clearly identified for quick selection.
Quality Assurance
All parts adhere to Yuchai Joint Power’s strict technical standards, with part numbers consistent with the original catalog. Key components use high-strength alloy and precision casting, ensuring durability under high torque. We offer an 18-month global warranty and 24-hour English technical guidance for installation and maintenance issues.
Practical Tips
For accurate selection, reference the original part number or provide your engine’s production batch. Our parts help restore the engine’s power output and fuel efficiency, minimizing vehicle downtime. Bulk orders enjoy preferential pricing—contact our team for compatibility confirmation and genuine Yuchai parts verification.
