Genuine Spare Parts & Maintenance
Genuine Yuchai spare parts and Zhiqiang maintenance kits for the generator sets we build. Pre-packaged service kits by interval (250h, 500h, 1000h, 3000h), individual components, and overhaul kits — shipped to all 7 ASEAN markets.
We build and sell complete diesel generator sets rather than engines or alternators on their own. The parts below are supplied for a Zhiqiang set you already own — tell the after-sales desk your set serial number and we confirm fitment.
Factory warranty is 12 months (1 year) on every set we build, benchmarked on the prime-power rating. Engine-side warranty work is raised with the nearest Yuchai service station in your market; our after-sales desk handles genuine parts, service kits and fitment confirmation.
