The Wacker Neuson Tension Spring is a genuine OEM component designed for the BS-series 4-stroke gasoline vibratory rammer line, including the BS50-4As, BS60-4As, BS65-4As, BS68-4As, BS70-4As, BS72-4As, BS62-4A/28, and BS68-4A/28 models. As a direct OEM replacement, part is manufactured to the same specification as the original, ensuring a drop-in fit with no guesswork. This spring supports the mechanical operation of the rammer's internal drive system, helping maintain consistent stroke performance in trench compaction and cohesive soil applications. Confirm your model number before ordering — this part covers a wide range of BS-series variants, including US, CN, and Sunbelt-designated configurations.
Key Features
- Genuine OEM Spring Tension Spec: — Manufactured to the original load and extension rating, so the rammer's percussion cycle stays consistent and predictable under working conditions.
- Drop-In Replacement: — Engineered to the same hook geometry and coil dimensions as the original, allowing direct installation without modification to mounting points or adjacent components.
- Broad BS-Series Coverage: — Compatible with BS50-4As, BS60-4As, BS65-4As, BS68-4As, BS70-4As, BS72-4As, BS62-4A/28, and BS68-4A/28 rammers across standard, US, CN, and Sunbelt configurations.
- Stroke Consistency: — A properly tensioned spring maintains the correct percussion rhythm in the rammer's drive mechanism; a fatigued or broken spring leads to erratic stroke, reduced compaction output, or a machine that won't run at all.
- Verified OEM Part Number: — Sourced directly from Wacker Neuson's parts program under part number 5100049230, so you're ordering the exact component called out in the service documentation.
The tension spring in a Wacker Neuson BS-series rammer plays a key role in the machine's internal drive linkage, storing and releasing mechanical energy to help regulate the timing and force of each percussion stroke. When the spring is correctly tensioned, the rammer delivers steady, repeatable blows into the soil — critical for achieving proper compaction density in trenches and tight spaces. As the spring fatigues or breaks, stroke force becomes inconsistent, the machine may stall or fail to develop full percussion, and compaction results can fall short of spec.
