Shijiazhuang Haoda Internal Combustion Engine Parts Co., Ltd.

Shijiazhuang Haoda Internal Combustion Engine Parts Co., Ltd. — established in 1992 and headquartered in Shijiazhuang, Hebei Province, China — is a specialist manufacturer of engine valve train components integrating research and development, manufacturing, export, and sales across more than three decades of focused internal combustion engine parts production. Haoda's product portfolio spans the complete valve train component set for diesel bus engines: intake and exhaust engine valves, valve guides, valve lifters (tappets), and valve rocker arms, with all production output passing 100% automated optical inspection at micrometer-level dimensional tolerances — a precision standard that directly determines valve sealing integrity, engine compression, and valve train service life on high-mileage bus diesel engines.!11!@aaaa

Indonesia's bus and coach fleet — spanning city transit buses, PO (Perusahaan Otobus) intercity coaches, and school and shuttle buses operating on Hino 300/500/700 Series, Isuzu Elf/Giga/FTR/FVR, Mitsubishi Fuso, and Mercedes-Benz OH/OF platforms — generates consistent, high-frequency demand for valve train overhaul components as engines accumulate mileage under full passenger load and Indonesia's tropical operating conditions. Cylinder head rebuilds, valve reseating, and rocker arm replacement are routine major-service events for PO fleet workshops and bus engine rebuild specialists across Java, Sumatra, and Kalimantan.
