Bomag 05766438 Vibration Module

The Bomag 05766438 Vibration Module is a genuine OEM component designed for a wide range of Bomag BW-series single drum and tandem rollers, including the BW 142 D-2, BW 213 D-3, BW 213 DH-3, BW 225 D-3, BW 138 AD, BW 135 AD, BW 120 AD-3, BW 151 AD-2, BW 202 AD-2, and many additional models across both roller families. Sourced directly from Bomag, this vibration module carries the same part number 05766438 found in the OEM service documentation, so you can order with confidence that this is the correct component for your machine. This module is a direct replacement unit, engineered to restore the drum's compaction output to the performance level your roller was built to deliver.

Key Features

• Genuine OEM Vibration Output — manufactured by Bomag to the exact eccentric mass configuration and frequency spec required for consistent compaction performance in single drum and tandem roller applications
• Direct Replacement Fitment — matches the original mounting interface and connection points of the factory-installed unit, allowing straightforward swap-out without modifications to brackets or drive connections
• Broad BW-Series Coverage — fits an extensive range of Bomag BW-series rollers including single drum models such as the BW 142 D-2, BW 177 D-3, BW 212 D-3, BW 213 D-3, BW 213 DH-3, BW 213 PDH-3, BW 214 DH-3, BW 216 DH-3, BW 219 DH-3, BW 219 PDH-3, BW 225 D-3, BW 178 D-3, and tandem rollers including the BW 80 AD-2, BW 90 AD-2, BW 100 AC-3, BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ACH, BW 135 AD, BW 138 AD, BW 141 AD-2, BW 151 AD-2, BW 202 AD-2, and more
• Restored Compaction Force — a worn or failed vibration module causes uneven compaction, surface defects, and failed density tests; replacing it with this OEM unit restores the drum's centrifugal force output and ensures consistent lift compaction
• Verified Part Number Traceability — part number 05766438 aligns directly with Bomag's OEM parts catalog, eliminating guesswork when cross-referencing your machine's service manual or parts diagram

The vibration module is the core assembly responsible for generating the oscillating force that a vibratory roller drum uses to compact soil, aggregate, or asphalt. It works by spinning an eccentric weight inside the drum shaft, creating centrifugal force that drives the drum into the material with each rotation. When the vibration module wears, becomes unbalanced, or fails entirely, the drum loses compaction energy — resulting in poor density results, increased pass counts, and potential damage to the drum drive system. Replacing this module with a genuine Bomag part restores the roller to its designed compaction output and protects the surrounding drivetrain components from the stress caused by an imbalanced or seized eccentric assembly.
