BALL - HYDRAULIC UNIT (Doosan DWA403788)

A worn ball within a hydraulic unit can disrupt fluid control and lead to erratic actuator movement. The Doosan catalog reference DWA403788 identifies this aftermarket replacement component. This ball functions as a sealing element that directs or blocks hydraulic flow within the unit. A common failure consequence is internal leakage, which reduces system pressure and causes sluggish or incomplete motion. In a typical usage context, this ball endures repeated contact with valve seats during normal cycling. The item ships at approximately 0.2 pounds.
