One New Aftermarket Replacement Barrel Assembly (Cylinder Block) for Caterpillar (Cat) Excavators
This aftermarket barrel assembly -- also known as a cylinder block -- is an internal component of the hydraulic travel motor on Caterpillar excavators. The barrel (cylinder block) houses the pistons inside the travel motor, converting pressurized hydraulic fluid into the rotational force that drives the track sprockets and propels the machine. Worn or damaged cylinder blocks cause sluggish travel, uneven track movement, and travel motor leakdown. Replaces Caterpillar OEM part number 173-4063 (1734063).
