The Wacker Neuson Breather Complete is a genuine OEM component designed for PTS4V centrifugal trash pumps, GPS9700 and GPS8500 portable generators, GS8.5V and GS9.7V generators, and the RD11V hydrostatic double drum vibratory roller. As a direct factory replacement, this Breather Complete matches the original specification for a drop-in installation with no guesswork. Sourced directly from Wacker Neuson, part ensures the engine crankcase ventilation system operates exactly as the machine was designed to perform. If you're servicing a PTS4V(I) pump or a GPS9700V generator and need a confirmed OEM replacement, this is the correct part.
Key Features
- Genuine OEM Crankcase Venting Spec — Manufactured to the original flow and pressure ratings for this breather assembly, ensuring correct crankcase pressure regulation across every covered model.
- Direct-Fit Replacement — Engineered to mount in the same position and connect to the same fittings as the original unit, supporting a straightforward swap during routine maintenance or repair.
- Broad Cross-Family Fitment — Confirmed for the PTS4V and PTS4V(I) trash pump series, GPS8500 and GPS9700 portable generator series, GS8.5V and GS9.7V generators, and the RD11V tandem roller.
- Engine Protection Through Proper Ventilation — A functioning breather assembly prevents crankcase pressure buildup that can force oil past seals and into the air intake, protecting engine internals from oil contamination and accelerated wear.
- Emissions and Combustion Compliance — A correctly operating breather routes blow-by gases back into the combustion process, keeping the engine within its designed emissions profile and preventing uncontrolled venting of combustion gases.
The breather complete is responsible for venting excess pressure that builds up inside the engine crankcase during normal combustion. Without a properly functioning breather, that pressure can force oil through gaskets and seals, contaminate the air-fuel mixture, and cause excessive oil consumption or fouled spark plugs. On equipment like the PTS4V trash pump and GPS9700 generator — machines often run hard in demanding site conditions — a worn or clogged breather can accelerate engine wear quickly, making timely replacement an important part of any service interval.
