One New Aftermarket Replacement Center Pin for Caterpillar (Cat) Excavators and Forestry Equipment
This center pin (replaces OEM part number 1772502) is a precision-fit linkage pin used in the boom, stick, or attachment linkage assembly on compatible Caterpillar (Cat) excavators and forestry machines. Center pins are critical wear components that maintain alignment and articulation in high-load pivot points. Replacing a worn or damaged center pin restores proper joint fit and helps prevent accelerated wear on surrounding bushings and bores.
