Product Overview

The Kawasaki P-2953801623KD Cylinder Spring Set contains genuine OEM high-fatigue tension components engineered specifically for the rotating group of Kawasaki K3VL80 series variable displacement axial piston pumps. These internal springs sit inside the cylinder block (barrel) bores behind the cylinder pins. By exerting continuous, precise outward mechanical force, they hold the cylinder block tightly against the valve plate and keep the piston slippers properly seated against the swashplate—ensuring immediate pump priming and preventing internal fluid bypass during low-pressure startup phases.
