The Wacker Neuson is a genuine OEM Welch Plug designed for the BS50-4 and BS60-4 series four-stroke vibratory rammers. As a direct factory replacement, this plug is manufactured to the exact dimensions required by the engine block passages found across the BS50-4, BS50-4s, BS60-4, and BS60-4s model lines, including EU-specification variants. Sourcing the correct Welch Plug by part number ensures a proper seal without the guesswork of cross-referencing aftermarket alternatives. If your rammer is due for an engine service or you've identified a sealing failure, this is the part to have on hand.
Key Features
- Exact OEM Sealing Dimensions — Manufactured to the precise diameter and thickness specified by Wacker Neuson, ensuring full compression into the bore without leakage gaps.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this plug carries the same specification as the original installed at the factory.
- Broad BS-Series Compatibility — Fits BS50-4, BS50-4s, BS60-4, BS60-4s, BS500-4, and BS600-4 vibratory rammers, including standard and EU-specification models.
- Protects Engine Internals — A correctly seated Welch Plug keeps oil and coolant passages sealed, preventing contamination and maintaining correct lubrication pressure throughout the engine.
- Fuel and Fluid System Integrity — A failed or dislodged plug can allow fluid migration into unintended passages, risking engine damage; replacement with the correct OEM part restores safe operating conditions.
A Welch Plug — sometimes called a Welsh plug or expansion plug — is a pressed-metal disc used to seal casting holes in an engine block that are created during the manufacturing process. In four-stroke rammer engines like those found in the BS50-4 and BS60-4 series, these plugs seal oil and fluid passages that would otherwise be exposed to the environment. Over time, corrosion, impact, or engine overheating can cause a Welch Plug to fail, resulting in fluid loss, contamination, or loss of internal pressure. Replacing a damaged plug promptly with the correct part prevents secondary engine damage and keeps the rammer operating at full compaction capacity.
