The Bomag 05804399 Eccentric Bolt is a genuine OEM component designed for Bomag BW 145 DH-3, BW 145 PDH-3, and C 825 C single drum rollers. Sourced directly from Bomag, this eccentric bolt delivers the exact geometry and material specification required for proper drum excitation and vibration system alignment. It installs as a direct OEM replacement, ensuring the vibration mechanism operates within the engineered tolerances your machine demands. Confirm part number 05804399 against your machine's parts manual before ordering to guarantee a correct match.
Key Features
- Genuine OEM Eccentric Geometry — manufactured to Bomag's original offset and dimensional spec, preserving the precise eccentric throw that drives correct vibratory output from the drum assembly
- Direct Drop-In Replacement — engineered to match the original mounting configuration on Bomag single drum rollers, so installation aligns with existing hardware without modification
- Broad Single Drum Roller Coverage — fits BW 145 DH-3, BW 145 PDH-3, BW145PDH 3, BW 145-DH-3, BW145DH 40, BW145PDH 40, BW 145 PDH 40, and C 825 C single drum rollers
- Vibration System Integrity — a correctly spec'd eccentric bolt maintains consistent amplitude and compaction force; a worn or out-of-spec bolt causes irregular vibration, reduced compaction efficiency, and accelerated bearing wear
- OEM Part Number Confidence — part number 05804399 is the authoritative Bomag reference for this component, giving you a verified cross-check against your service documentation
An eccentric bolt is a precision offset fastener positioned within the drum's vibration shaft assembly. As the shaft rotates, the bolt's offset mass generates the centrifugal force that drives the drum's vibratory compaction action — without the correct eccentric geometry, the drum cannot produce the amplitude or frequency the machine was designed to deliver. When this bolt wears, becomes damaged, or is replaced with an incorrect substitute, compaction performance drops noticeably and bearing loads become uneven, shortening the service life of surrounding drivetrain components.
