New Holland 2404N271 Drive Sprocket

The 2404N271 drive sprocket is engineered for the undercarriage system of mid-size hydraulic excavators. It features 21 teeth with an inner diameter of 324 mm and an outer diameter of 601 mm, utilizing 15 bolt holes for final drive mounting. The component is manufactured from 40SiMnTi or 40Mn2 alloy steel through forging, precision machining, and heat treatment processes including overall hardening and induction hardening of tooth profiles to ensure high wear resistance and fatigue strength under heavy load conditions. The sprocket serves as a direct OEM replacement for New Holland excavator models E115SR, E135SR, E135SRLC, EH130, and E130. It cross-references to Kobelco part numbers for SK100, SK120, and SK115SR series machines, reflecting shared platform architecture. Interchange numbers include V2404N271V, 2404N254, 2404N416, 09-11-0007, R1610000Y01, and VR1610000Y01.
