Wacker Neuson 5100009684 WM 80 Engine

The Wacker Neuson WM 80 Engine is a genuine OEM engine assembly designed for the BS50, BS60, and BS70 series gasoline vibratory rammers. As a factory-sourced component, it is built to the exact specifications of the original unit, ensuring a true drop-in replacement for any of the covered rammer configurations. Fitment spans a wide range of BS50-2i, BS50-2plus, BS60-2i, BS60-2plus, BS70-2i, and BS70-2plus variants — including standard, high-altitude, and specialty shoe configurations. When your rammer's engine is beyond repair, the is the correct, authoritative replacement to restore full operational capacity.

Key Features

• Genuine OEM Engine Assembly — Sourced directly from Wacker Neuson, this WM 80 Engine meets the exact displacement, output, and component tolerances of the original powerplant — no guesswork on performance specs.
• Broad BS-Series Rammer Compatibility — Fits BS50-2i, BS50-2plus, BS60-2i, BS60-2plus, BS70-2i, and BS70-2plus rammers, covering standard, high-altitude, and multiple shoe-size configurations.
• Complete Engine Unit — Supplied as a full engine assembly, allowing a straightforward swap-out on the rammer frame without sourcing individual internal components separately.
• Restores Full Compaction Output — A correctly functioning WM 80 Engine delivers the consistent power stroke frequency that BS-series rammers depend on for effective trench and cohesive soil compaction; a worn or seized engine means zero productive compaction.
• Fuel System Integrity — As a genuine OEM unit, the engine ships with correct carburetion and ignition calibration for the BS-series platform, supporting proper fuel delivery and clean starting right out of the box.

The WM 80 is the dedicated gasoline engine at the heart of Wacker Neuson's BS-series vibratory rammers. It generates the rotational force that drives the rammer's eccentric mechanism, producing the rapid up-and-down impact strokes needed to compact cohesive soils, trench backfill, and granular material in confined spaces. When the engine loses compression, fails to start, or delivers inconsistent power, the rammer cannot maintain its rated impact energy — compaction quality drops and productivity stalls. Replacing the engine with the correct OEM unit, part number 5100009684, restores the machine to its original rated performance and gets the rammer back to work.
