1733496 Barrel As Fits Caterpillar Models

One New Aftermarket Replacement Hydraulic Barrel Assembly for Caterpillar (Cat) Excavators

This aftermarket replacement barrel assembly (cylinder block) is a core rotating-group component of the main hydraulic piston pump on Caterpillar (Cat) C-series and D-series hydraulic excavators. The barrel houses the reciprocating pistons that generate hydraulic flow to power the boom, arm, bucket, and swing systems. Replacing a worn or scored barrel restores pump efficiency and helps return the machine to full hydraulic performance.
