Excavator Pump Parts HPV75 SET PLATE 708-1W-23340 For Pc60-6 Pc60-7 Excavator

Located between the Piston Shoe and Swash Plate, it is a circular steel plate with round holes corresponding one‑to‑one to the number of pistons. The tail of each piston shoe passes through these holes.

It works as a matched component with the Ball‑Guide: Cylinder Block → Ball‑Guide → Set‑Plate → Piston Shoe → Swash Plate

Core Functions

Retain piston shoes (return‑stroke function): During the piston return stroke, the set‑plate presses all piston shoes firmly against the swash‑plate surface to prevent the shoes from separating from the swash plate.

Synchronous limiting: Drives all piston shoes to rotate together with the cylinder block, ensuring synchronous operating positions for every shoe.

Positioning constraint: Restricts radial play of the piston shoes.
