Description
Overview:
This is a Genuine Wacker Neuson piston ring for WM80 two‐stroke engines, used on compactors/rammers and breakers such as the BS50‐2 and BS60‐2. The ring maintains cylinder sealing and compression to support reliable starting, stable power, and lower fuel consumption. Manufactured to OEM standards by Wacker Neuson, it is identified by MPN 5000045904 and sized for a 43.2 mm inner diameter. Made from high‐quality wear‐resistant steel, it is engineered to cope with heat, friction, and the dusty conditions common on construction and hire sites. Suitable for routine maintenance or a top‐end refresh, this piston ring helps restore performance when the engine shows symptoms of wear such as hard starting, loss of power, or increased smoke.
