Product Overview

This premium aftermarket center pin (also referred to as a cylinder block pin or alignment pin) is a high-precision rotating group alignment component engineered specifically for the HPV118 series variable displacement axial piston pumps. Positioned at the exact geometric core of the pump barrel, this center pin serves as the primary structural guide that centers and stabilizes the cylinder block. Working in tandem with the core spring, it maintains a continuous, perfectly balanced mechanical alignment, keeping the spinning cylinder barrel flush against the valve plate and the piston slippers seated against the swashplate.
