The Bomag 05794078 Eccentric Assembly is a genuine OEM component designed for a wide range of Bomag walk-behind light rollers and tandem rollers, including the BW 75 ADL, BW 120 AD-3, BW 138 AD, BW 135 AD, BW 151 AC-2, BW 161 AC-2, and BW 164 AC-2, among others. Sourced directly from Bomag, this assembly meets the same production standards as the original part fitted at the factory. It delivers a direct, drop-in replacement with no guesswork on fit or function. Whether you're servicing a BW 100 AD-3 tandem roller or a BW 90 AD-2, part number 05794078 restores the drum's vibratory system to proper working order.
Key Features
- Genuine OEM Precision — manufactured by Bomag to exact eccentric mass and balance specifications, ensuring correct vibration amplitude and frequency output from the drum
- Direct Replacement Fit — engineered to seat and connect identically to the original assembly, compatible across an extensive range of BW tandem and light roller models
- Broad Fitment Coverage — fits BW tandem rollers including the BW 80 AD-2, BW 90 AC-2, BW 120 AC-3, BW 125 ADH, BW 135 AC, BW 138 AC, and the BW 75 ADL walk-behind light roller
- Restored Compaction Performance — a worn or damaged eccentric assembly causes uneven vibration, reduced compaction force, and drum instability; replacing it brings the machine back to full output
- Long-Term Drivetrain Protection — correct eccentric balance reduces stress on drum bearings and the vibratory drive system, extending the service life of surrounding components
The eccentric assembly sits inside the roller drum and is the core of the machine's vibratory compaction system. As it rotates at high speed, its off-center mass generates the centrifugal force that causes the drum to vibrate, pressing and consolidating the surface material below. When the eccentric assembly is worn, damaged, or out of balance, vibration output drops or becomes irregular, leading to poor compaction results, increased drum bearing wear, and operator-felt roughness through the machine. Replacing the assembly with a genuine Bomag part restores consistent, controlled vibration and keeps the roller performing to its rated compaction capacity.
