Hitachi excavator Isuzu 1-12511255-2 eccentric shaft

Hitachi Excavator 1-12511255-2 eccentric shaft (camshaft/Camshaft) is the core valve train component of the ISUZU 6WG1 engine, directly responsible for valve timing control, compression pressure establishment, and engine valve sequence. Specially designed for precise matching of medium and large excavators such as ZX450-3, ZX470-5G, ZX500LC-3, etc., it adopts high-strength cast iron/alloy steel material, high-precision machined valve shaft, roller tappet, and high-temperature resistant sealing ring, with stable valve clearance, precise valve distribution, anti vibration, and anti wear. Perfectly solve problems such as unstable engine idle, insufficient power, decreased compression pressure, valve leakage, abnormal sound, weak walking (due to engine power attenuation), and high oil and water temperature.
