Caterpillar Inc. 258-4319 Armbar Assembly Right Hand

Caterpillar 258-4319 Armbar Assembly, Right-Hand, is a skid-steer replacement component that attaches to the machine’s right-side armbar. It carries part number 258-4319 and is specified to fit Caterpillar skid-steer models 226D3 through 299D2. This right-hand armbar assembly is used to replace a worn or damaged RH arm component on compatible Caterpillar units, helping restore proper alignment and operation of the arm mechanism on those models. As part of the loader arm system, this assembly supports the structural linkage that governs the movement of the right-hand arm on 226D3–299D2 machines. Because models in the 226D3 through 299D2 family vary by serial range and configuration, confirming exact fitment with your machine is recommended.
