Description
Overview:
This Cylinder & Piston assembly is a Genuine Wacker Neuson part for the WM80 2‐stroke engine with an oval exhaust port (part no. 5000176400). Built for breakers and rammers that work hard on site, it restores correct compression and combustion efficiency to keep your tools starting well and delivering full power. The cylinder is a high‐grade alloy casting with a precision‐machined bore for good heat dissipation and wear resistance, while the matched piston is engineered for accurate fit and reliable sealing. Designed to OEM tolerances, it integrates cleanly with existing components on WM80-powered equipment such as the BH65 and BS60-2, helping maintain dependable performance, low vibration, and consistent output under demanding compaction and breaking tasks.
