PLUNGER - SPRING (Doosan DWKO3EB-33-31220)

A worn plunger spring can cause erratic operation or failure of the component it actuates. This aftermarket replacement part references Doosan as the OE maker and cross-references part number DWKO3EB-33-31220. The plunger spring provides the mechanical force to return a plunger to its rest position after actuation. If the spring loses tension, the plunger may not fully retract, leading to binding or incomplete engagement. In a typical application, the spring must maintain consistent pressure over repeated cycles to ensure reliable performance. Verify the serial number or application, then call (562) 693-7748.
