7156580 Boom Cylinder Seal Kit — Product Overview

The 7156580 Boom Cylinder Seal Kit is a precision aftermarket replacement for Bobcat 430 excavator boom cylinders. Engineered for 1-3/4″ rod and 3-1/4″ bore hydraulic cylinders, this kit provides complete reseal coverage for the lift function on Bobcat 430 series excavators.

The boom cylinder on the Bobcat 430 handles the heaviest lifting loads — raising and lowering the entire front attachment including boom, arm, and bucket under full material weight. Seal failure in the boom circuit results in boom drift during stationary holding, reduced lifting capacity, and external oil leakage. The 7156580 kit addresses these failure modes with application-matched seal compounds.

Manufactured with high-performance polyurethane rod seals and NBR static seals etc for reliable fluid containment across the full operating temperature range of Bobcat excavators. DJF Seals supplies the 7156580 at factory-direct wholesale pricing — a dedicated boom cylinder solution for the Bobcat 430 platform.
