The Wacker Neuson Breather Tube is a genuine OEM component designed for the GS6503G and GS6500G generator series. Sourced directly from Wacker Neuson, this is the exact part used in original production — no guesswork on fit or compatibility. As a genuine OEM replacement, the meets every factory specification for these generator models, ensuring a correct, trouble-free installation. If your GS6503G or GS6500G is showing signs of crankcase pressure buildup or oil misting, replacing the breather tube with the correct OEM part is a straightforward fix that restores proper engine ventilation.
Key Features
- Correct Tube Routing and Connection Points — Manufactured to the exact profile and end fittings of the original, so it seats and seals properly without modification.
- Genuine OEM Venting Integrity — Produced to Wacker Neuson's material and dimensional specifications, ensuring the tube maintains consistent airflow and resists crankcase pressure and heat over time.
- Direct Fit for GS6503G and GS6500G Generators — Verified compatible with GS6503G CE and GS6500G LA model variants; cross-reference part number 5000408738 before ordering to confirm your unit.
- Restores Proper Engine Breathing — A functioning breather tube prevents pressure buildup in the crankcase, protecting seals and gaskets from oil leaks and keeping combustion gases out of the oil supply.
- Straight Swap, No Downtime Guessing — Because this is the genuine OEM part, you get the same geometry and material as the component it replaces — drop it in and get back to work.
The breather tube connects the engine crankcase to the air intake or atmosphere, allowing pressure generated during normal combustion to vent safely rather than build up inside the engine. Without a properly functioning breather tube, excess crankcase pressure can force oil past seals and gaskets, leading to leaks, contaminated air filters, and accelerated engine wear. A cracked, blocked, or deteriorated breather tube should be replaced promptly to protect the engine and maintain clean, efficient operation.
