The Wacker Neuson 5100039952 is a genuine OEM Guide Cylinder designed for the BS70 series gasoline vibratory rammers, including the BS70-4As, BS70-2plus, and BS70-2 models. As a factory-sourced component, it is manufactured to the exact tolerances required for correct stroke geometry and consistent compaction performance in trench and cohesive soil applications. Fitment covers both standard and US-spec configurations across the BS70 family, making it the right choice when restoring a BS70 rammer to full operating condition. Always confirm your machine's part number before ordering to ensure a precise match.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact bore and stroke tolerances, ensuring the piston travels true and the ramming force is delivered consistently with every impact cycle.
- Drop-In Fitment for BS70 Series — Engineered specifically for the BS70 platform; installs directly into the existing rammer housing without machining or modification to mating components.
- Broad BS70 Coverage — Compatible with BS70-4As (standard and US-spec), BS70-2plus (standard and US-spec), and BS70-2 models, covering a wide range of 11-inch rammer configurations.
- Sustained Compaction Output — A correctly fitted Guide Cylinder maintains the full impact energy of the rammer; a worn or out-of-spec cylinder causes loss of stroke, reduced blow force, and uneven soil compaction in trenches.
- Sourced Direct from Wacker Neuson — Carries full OEM part traceability, so you can be confident the component meets the same standard as the original part it replaces.
The Guide Cylinder is a core structural component within the rammer's percussion mechanism. It acts as the guided bore through which the piston reciprocates, converting engine-driven motion into the high-impact blows needed to compact cohesive soils and trench backfill. When the Guide Cylinder wears, becomes scored, or loses dimensional integrity, the piston can no longer travel freely and accurately — resulting in reduced impact force, erratic operation, and accelerated wear on surrounding components. Replacing a worn Guide Cylinder restores the rammer's full compaction energy and helps protect the broader percussion assembly from further damage.
