Xinchai Forklift Valve Rocker Arm Assembly 490B-03200 – 490 495 498 4D27G31 Hanzhi OEM

Xinchai Forklift Valve Rocker Arm Assembly 490B-03200 — 490/495/498/4D27G31, Kingstream OEM

This is the complete valve rocker arm assembly (part number 490B-03200) for Xinchai 490, 495, 498, and 4D27G31 series diesel engines — the most common engine platform in Chinese-made IC forklifts including HELI, Hangcha, and Lonking 2-3.5 ton models. The assembly includes the full-length rocker shaft (420mm total length), individual rocker arms for each valve, adjusting screws with locknuts, and shaft mounting pedestals — a complete bolt-on replacement for the entire valve actuation system. The 490-series Xinchai engine is the workhorse of Chinese material handling, powering tens of thousands of forklifts across the world, and the 490B-03200 rocker assembly is the most commonly replaced valve train component during engine overhauls because the exhaust rocker pads wear faster than intake pads due to higher operating temperatures.

This Kingstream brand assembly is manufactured in China with 100% professional testing and a 6-month warranty. Iron steel material with iron black color. Net weight: 3.0 kg, package: 45×20×20cm. The complete 420mm shaft assembly replaces all rocker arms, bushings, shaft, and adjusting screws simultaneously — more cost-effective than diagnosing and replacing individual worn components. Torque pedestal bolts in correct sequence to prevent shaft bending and uneven oil distribution.

Compatible with Xinchai 490, 495, 498, and 4D27G31 diesel engines in HELI, Hangcha, and Lonking forklifts. Browse our valve rocker selection for HELI CPCD and Changchai engines.
