Product Description
Compatibility & Application
All parts are 100% compatible with Yuchai YC6G270-30(G5AQP) 6-cylinder turbocharged intercooled diesel engine. Designed for heavy-duty trucks, medium/heavy buses and construction machinery, our parts perfectly match the engine’s high-load and long-working-hour characteristics, meeting routine maintenance, major overhaul and emergency repair needs.
Parts Coverage
Our parts fully cover the engine’s core systems: power core (cylinder block, cylinder head, piston-rod assembly), fuel & air (injection pump, injector, turbocharger, intake/exhaust manifold), lubrication & cooling (oil pump, filter, cooler, water pump), and electrical & auxiliary (starter, alternator, steering pump, control system). EWP-marked easy-wear parts (piston rings, gaskets, oil seals) are clearly identified for quick selection.
Quality Assurance
All parts adhere to Yuchai’s strict technical standards, with dimensions and materials consistent with original equipment. Key components use high-strength alloy and precision casting, ensuring durability under high torque and high load. We offer an 18-month global warranty (excluding human-induced damage) and 24-hour English technical guidance to support installation and maintenance.
Practical Tips
For accurate part selection, please 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 customized support, including original Yuchai parts verification and compatibility confirmation.
