As a leading enterprise in China's power industry, Guangxi Yuchai Machinery Co., Ltd. (hereinafter referred to as "Yuchai") continues to provide reliable power support to customers in more than 180 countries and regions worldwide with its G-drive diesel engines, renowned for outstanding product performance and a comprehensive global after-sales service system. From manufacturing plants in Southeast Asia to infrastructure projects in Africa, from oil and gas fields in the Middle East to mining sites in South America, Yuchai has earned widespread trust from overseas customers with its service philosophy of "global warranty, rapid response, and parts-first."
I. Global Service Network: Covering Five Continents with Worldwide Warranty Coverage
Yuchai has always regarded the development of its after-sales service system as a core pillar of its internationalization strategy. Through years of strategic deployment, Yuchai has established 29 overseas marketing offices across Asia, the Americas, Africa, and Europe, developed more than 840 service agents, and built over 1,500 overseas service outlets, achieving full coverage of global warranty services.
Domestically, Yuchai has likewise built an industry-leading service network, setting up 13 marine & G-drive overseas marketing centers to coordinate the sales and service of power generation engines, supported by more than 6,300 service stations and over 6,000 spare parts sales outlets, forming a service pattern of "domestic and international dual-network linkage."
To date, Yuchai engine products have been exported to more than 180 countries and regions worldwide, with cumulative overseas market holdings exceeding 560,000 units and an annual export volume of 50,000 units, making it one of the Chinese engine enterprises with the largest overseas holdings in the industry.
II. Rapid Response Mechanism: 10-Minute Response, 1.5-Hour On-Site Arrival
Relying on its intelligent service system and the 95098 customer service team, Yuchai provides round-the-clock, year-round service support to global users. In the domestic market, Yuchai commits to "10-minute response, 30-minute dispatch, and 1.5-hour on-site arrival," achieving industry-leading service efficiency.
In overseas markets, Yuchai has likewise established stringent service response standards: work orders are dispatched within 1 hour after a customer reports a fault, with timely feedback on arrangements provided to the customer. For on-site arrival, service personnel arrive within 3 hours in urban areas, 6 hours within 200 kilometers, and 12 hours beyond 200 kilometers (excluding remote areas). Commonly used spare parts are delivered within 24 hours. For completion timelines, first-time maintenance takes no more than 3 hours, and general faults are resolved within 8 hours.
To further enhance service efficiency, Yuchai took the lead in the industry in promoting its "Micro+" service in 2014, fully implementing web-based and mobile-based fault reporting. Leveraging onboard terminals, Yuchai provides proactive preventive maintenance services, transforming "passive emergency repairs" into "active prevention," thereby minimizing customer downtime losses.
III. Spare Parts Assurance System: Forward-Deployed Central Warehouses with a 10-Year Supply Commitment
As critical power backup equipment, generator sets impose extremely high demands on the timeliness and reliability of spare parts supply. Yuchai has established spare parts central warehouses and brand image stores in key overseas markets, achieving localized inventory and rapid distribution of spare parts in countries such as Vietnam, the Philippines, and Saudi Arabia.
Taking the Vietnamese market as an example, Yuchai has built 3 spare parts central warehouses and 21 first-tier service stations covering the entire territory of Vietnam, ensuring after-sales service and spare parts demand for the full range of Yuchai products in the Vietnamese market. During the severe power shortage in Vietnam in 2023, Yuchai's VTD and VC series high-power generator sets served local high-end manufacturing factories. Relying on its comprehensive spare parts and service network, Yuchai provided robust support for continuous enterprise production.
In addition, Yuchai commits to a 10-year spare parts supply guarantee for all exported product series, and provides end customers with electronic technical documentation including the Engine Operation and Maintenance Manual, Parts Catalog, and Maintenance Manual, covering the full range of exported products to provide reliable technical guidance for market service training and customer self-maintenance.
IV. Marine & G-drive Professional Services: Focused on Power Generation Scenarios with Customized Solutions
Yuchai's G-drive diesel engines fall under the marine & G-drive business segment, encompassing multiple series including YC6K, YC6T, YC6MK, VTD, and VC, with a broad power coverage range that can meet diverse power demands from standby to prime power, and from continuous to standby duty.
In response to the operational characteristics of G-drive engines, Yuchai has established 13 marine & G-drive overseas marketing centers and formed a professional marine & G-drive service team, providing customers with full-lifecycle services from unit selection, equipment room design, commissioning and handover to daily maintenance and major overhaul. Diesel generator sets come with a 12-month warranty from the date of purchase; specific part warranty periods are detailed in the accompanying Warranty Manual.
During the commissioning and handover phase, Yuchai commits to dispatching technical service personnel to arrive at the customer's designated location within 24 hours of receiving the customer's startup application, completing installation guidance and commissioning of the unit in accordance with standard commissioning procedures, and ensuring the unit enters service in optimal condition.
V. Digital Empowerment: The YCSS System Driving Service Upgrades
Yuchai's independently developed YCSS Service Information Management System serves as the "intelligent brain" of its global after-sales service system. The system enables full-process digital management of service work orders, from customer fault reporting and dispatch scheduling to on-site service, spare parts requisition, and completion acceptance—every step is traceable and monitorable.
Through the YCSS system, Yuchai headquarters can monitor the operational status of global service outlets in real time, dynamically tracking and continuously optimizing key indicators such as service response time, completion rate, and customer satisfaction. Meanwhile, the massive operational data and fault cases accumulated by the system also provide data support for product improvement and preventive maintenance.
Conclusion
From "taking products global" to "taking services global," the continuous improvement of Yuchai's G-drive diesel engine global after-sales service system is not only a reflection of the enterprise's internationalization capabilities but also a fulfillment of its mission to "satisfy the public's power needs with excellence and leadership" for global customers.
Looking ahead, Yuchai will continue to deepen the layout of its global service network, accelerate the digital transformation of services, and enhance localized spare parts supply capabilities. With faster response, more professional technology, and more reliable assurance, Yuchai will safeguard the power security of global customers, making "Yuchai Power" a trusted choice for users worldwide.
