The Wacker Neuson 0183035 WM 100 Engine with Purge Bulb is a genuine OEM power unit designed for the BS50-4s and BS60-4s series four-stroke vibratory rammers. Sourced directly from Wacker Neuson, this complete engine assembly carries the exact fit and specification required to restore your rammer to full working order. It is compatible across a wide range of BS50-4s and BS60-4s configurations, including standard, EU, and high-altitude variants. When your rammer's engine fails or sustains damage beyond repair, this OEM assembly delivers the most direct path back to full compaction performance.
Key Features
- Complete Engine Assembly with Purge Bulb Included — Ships as a self-contained unit with the purge bulb pre-integrated, so the priming system is ready to go from the start.
- Genuine OEM Construction — Manufactured to Wacker Neuson's own displacement, compression, and output specifications for the WM 100 engine family — no guesswork on compatibility.
- Broad BS-Series Fitment — Confirmed fit across multiple BS50-4s and BS60-4s configurations, including standard, EU-spec, and high-altitude variants with 280mm/11 in shoes.
- Restores Full Compaction Output — A healthy WM 100 engine delivers the consistent stroke energy these rammers depend on for trench and cohesive soil compaction; a failing engine directly reduces impact force and productivity.
- Fuel System Integrity — The included purge bulb ensures proper fuel priming before startup, supporting clean combustion and reliable cold starts in field conditions.
The WM 100 is the four-stroke gasoline engine at the heart of the Wacker Neuson BS50-4s and BS60-4s vibratory rammers. It drives the eccentric mechanism that generates the rapid up-and-down impact force these machines use to compact cohesive soils, clay-heavy fills, and trench backfill. The purge bulb is a small but critical component of the fuel delivery system — pressing it before startup clears air from the fuel line and draws fresh fuel to the carburetor, making cold starts faster and more consistent. When the engine loses compression, runs rough, or fails to start reliably, compaction force drops off and the machine becomes unreliable on the job. Replacing the engine assembly with the correct OEM unit, part number 0183035, is the most effective way to bring a BS50-4s or BS60-4s rammer back to its rated performance.
