Product Description
Confirm Compatibility
All parts are 100% compatible with Yuchai YC4S140-48(S56D1) turbocharged diesel engine. With 3.8L displacement, 103kW rated power, and Euro IV compliance, this engine is widely used in medium/light-duty trucks and 4×2 vans. Our parts are tailored for its low-noise, fuel-efficient (199g/kW·h) design, meeting routine maintenance and emergency repair needs.
Parts Coverage
Our parts cover core systems of the engine: power core (cylinder block, piston, crankshaft damper), fuel & emission (injection pump, turbocharger, EGR), lubrication & cooling (oil pump, filter, water pump), and electrical & auxiliary (alternator, starter, ECU). EWP-marked wear parts are easy to identify.
Quality Assurance
All parts adhere to Yuchai’s technical standards, with part numbers matching the original catalogue. Key components use high-strength materials; wear parts pass strict tests. We offer an 18-month or 150,000km warranty, plus 24-hour English technical guidance and global after-sales service for seamless installation.
Practical Tips
For accurate selection, reference the original part number or provide your engine’s production batch. Our parts restore fuel efficiency and dynamic performance, minimizing downtime. Bulk orders enjoy preferential pricing—contact our team for tailored recommendations and support.
