One New Aftermarket Replacement Spacer for Caterpillar (Cat) Large Excavators
This aftermarket replacement spacer (part number 1588970) is a precision-fit internal component used in the swing motor and hydraulic drive assemblies of Caterpillar large hydraulic excavators and front shovels. These large-frame machines rely on properly dimensioned spacers to maintain correct component stack-up, bearing preload, and clearance within the swing and hydraulic drive systems. Replacing worn or damaged spacers with a correctly specified part helps preserve the integrity of the surrounding assembly and prevents accelerated wear.
