The Wacker Neuson WM 100 Engine With Purge Bulb is a genuine OEM power unit designed for BS50-4s and BS60-4s series vibratory rammers. As a direct Wacker Neuson OEM component, part is manufactured to the same specification as the original, ensuring a drop-in fit with no guesswork on compatibility. This engine assembly is confirmed across a wide range of BS50-4s and BS60-4s configurations, including standard, EU, and high-altitude variants. If your rammer has lost power, won't start, or shows signs of engine wear, the is the correct replacement to restore full compaction performance.
Key Features
- Genuine OEM Engine Assembly — Sourced directly from Wacker Neuson, this unit matches the original WM 100 engine spec for correct displacement, output, and mounting dimensions on BS-series rammers.
- Integrated Purge Bulb Included — The purge bulb is part of the assembly, eliminating a common separate purchase and ensuring the fuel priming circuit is ready to install as a complete unit.
- Broad BS-Series Compatibility — Fits a wide range of BS50-4s and BS60-4s vibratory rammer configurations, including standard, EU-spec, and high-altitude models with 280mm/11 in shoes.
- Restores Full Compaction Force — A fresh engine brings the rammer back to rated impact energy output, critical for proper trench backfill and cohesive soil compaction that a worn or seized engine cannot deliver.
- Verified Part Number Fit — Part number 0183035 is cross-referenced across multiple BS50-4s and BS60-4s machine numbers, so you can order with confidence that this is the correct engine for your unit.
The WM 100 is a four-stroke gasoline engine purpose-built for Wacker Neuson BS-series vibratory rammers. It drives the eccentric mechanism that generates the rapid up-and-down impact force rammers rely on to densify cohesive soils, clay, and trench backfill — applications where a plate compactor cannot achieve adequate compaction depth. When the engine loses compression, burns oil, or fails to start reliably, the rammer delivers inconsistent or insufficient compaction force, which can compromise trench stability and subgrade integrity. Replacing the engine assembly with a genuine OEM 0183035 unit restores the machine to its original operating condition and rated performance.
