The Wacker Neuson Eccentric Fastener Bolt is a genuine OEM component designed for BS65-V, BS650, and BS65Y series variable speed vibratory rammers. As a direct OEM replacement, part is produced to the same specifications as the original hardware, ensuring it seats and torques correctly within the rammer's eccentric drive assembly. This bolt is confirmed to fit multiple BS65 variants, including EU-spec and BG Bau approved configurations with the 280 mm / 11 in shoe. Keeping this fastener in sound condition is essential to maintaining the integrity of the eccentric mechanism and the overall compaction performance of your rammer.
Key Features
- OEM-Grade Fastener Specification — Manufactured to the original thread pitch, shank diameter, and hardness rating required by the eccentric drive assembly, so torque load is transferred correctly without risk of stripping or backing out.
- Drop-In Installation — Matches the original bolt position in the eccentric housing, allowing straightforward removal and reinstallation using standard tooling with no reworking of mounting points.
- Broad BS65 Series Coverage — Fits BS65-V (including EU and BG Bau approved models), BS650, and BS65Y variable speed rammers equipped with the 280 mm / 11 in shoe.
- Eccentric Drive Integrity — A worn or loosened eccentric fastener bolt allows unwanted movement in the drive assembly, causing uneven impact force, accelerated wear on surrounding components, and inconsistent soil compaction.
- Critical Retention Component — This bolt secures a high-vibration rotating assembly; using a correctly rated OEM fastener rather than a generic substitute is important for safe, consistent operation of the rammer.
The eccentric fastener bolt secures the eccentric weight within the rammer's drive mechanism — the rotating component responsible for generating the rapid up-and-down impact strokes that compact cohesive soils and trench backfill. If this bolt loosens or fails, the eccentric weight can shift out of alignment, causing a noticeable drop in impact force, irregular jumping action, and rapid wear on the bearing surfaces and housing around it. Replacing a damaged or missing eccentric fastener bolt promptly restores the correct dynamic balance of the drive assembly and protects the surrounding components from secondary damage.
