Hitachi 4352400 Arm Bushing Assembly

The 4352400 arm bushing is a precision-engineered hydraulic cylinder pivot bushing designed for Hitachi and John Deere hydraulic excavators. Manufactured from heat-treated alloy steel, it serves as a wear-resistant interface in the H-link and arm cylinder pivot assemblies, reducing friction and absorbing shock loads at bucket-to-arm connections. This bushing fits multiple excavator platforms including Hitachi EX120-5, EX130H-5, EX150LC-5, EX200-3, ZX120, ZX120-3, ZX200, ZX200-3 series and John Deere 130G, 135G, 160GLC, 200DLC, 210G, 225DLC, 245GLC, 350GLC, 370C models. It replaces OEM part number 4352400 for both Hitachi and John Deere applications. Material composition: Precision-machined, heat-treated steel. Application: Open-end bushing installed in H-link at bucket pivot point and arm cylinder rod end. Designed for fit, form, and function equivalence to OEM specifications.
