Bomag 05817042 Vibration Motor

The Bomag 05817042 Vibration Motor is a genuine OEM component designed for Bomag BW 177 and BW 179 series single drum rollers. Sourced directly from Bomag, this vibration motor meets the exact specifications of the original unit, ensuring consistent hydraulic-driven vibration output across supported machine configurations. This component is confirmed to fit multiple generation variants of the BW 177, including D-3, D-4, D-40, D-50, DH-4, DH-40, DH-50, PDH-4, PDH-40, and PDH-50 models, as well as the BW 179 DH-4 and BW 179 PDH-4 single drum rollers — making it a dependable choice when restoring compaction performance to your machine.

Key Features

• Genuine OEM Hydraulic Output Matching — manufactured to Bomag's original displacement and pressure ratings, so this vibration motor delivers the same eccentric-shaft speed and compaction force as the unit it replaces
• Direct-Swap Installation — this motor replicates the original port configuration and mounting pattern, allowing straightforward installation without machining or adapter fittings
• Broad BW 177 and BW 179 Coverage — compatible with BW 177 D-3, BW 177 D-4, BW 177 D-40, BW 177 D-50, BW 177 DH-4, BW 177 DH-40, BW 177 DH-50, BW 177 PDH-4, BW 177 PDH-40, BW 177 PDH-50, BW177D 40, BW177PDH 40, BW 179 DH-4, and BW 179 PDH-4 single drum rollers
• Compaction Consistency Restored — a worn or failing vibration motor reduces drum amplitude and frequency, leading to uneven soil compaction; replacing it with an OEM unit brings drum performance back to specification
• Verified Part Number Traceability — ordering by Bomag part number 05817042 confirms you are receiving the correct motor for your machine generation, avoiding costly mismatches on hydraulic-driven assemblies

The vibration motor is a hydraulic-driven component that powers the eccentric weight assembly inside the compaction drum. As hydraulic fluid flows through the motor under pressure, it rotates the eccentric shaft, generating the vibratory force that allows the drum to compact soil, gravel, or subbase material with each pass. When the vibration motor wears internally — through seal degradation, cavitation, or bearing failure — drum vibration weakens or stops entirely, leaving the machine unable to achieve the required compaction depth. Replacing the motor with a genuine OEM unit restores full amplitude and frequency to the drum, ensuring the roller performs to its rated compaction output.
