Product Overview

The P-37033400481K Cylinder Spring is a genuine Kawasaki OEM heavy-duty internal component precision-engineered to restore original equipment performance in high-output hydraulic machinery. Alternatively classified as a cylinder block spring, central spring, or barrel spring, this high-tension component forms the structural core of the pump or motor rotating group. Because this is a genuine Kawasaki part, it is manufactured exactly to factory tension tolerances using premium spring steel. It provides the essential, constant mechanical force required to keep the cylinder block perfectly pressed against the valve plate and the piston shoes loaded against the swash plate. It functions as a direct-fit replacement component vital for preventing internal fluid separation, maintaining immediate system pressure, and safeguarding the rotary group from catastrophic mechanical breakdown.
