The Bomag 58002271 Left Assembled Exciter Unit is a genuine OEM component designed for BW 211 and BW 212 series single drum rollers. Sourced directly from Bomag, this exciter unit delivers the exact eccentric mass configuration and shaft geometry required for correct vibratory drum performance on compatible machines. This unit is confirmed to fit multiple BW 211 and BW 212 variants, including the BW 211 D-4, BW 211 D-5, BW 211 DE-40, BW 211 D-40, BW 211 D-50, BW 211 PD-3, BW 212 D-40, BW 212 D-5, and additional generation variants across the series.
Key Features
- Genuine OEM Eccentric Mass Accuracy — matched to Bomag's original eccentric weight specification so amplitude and frequency output remain within the drum's designed operating range
- Left-Side Direct Replacement — assembled and ready to install as the left exciter unit, dropping into the drum housing without modification to mounting flanges or shaft interfaces
- Broad BW 211 and BW 212 Coverage — fits BW 211 D-4, BW 211 D-5, BW 211 D-40, BW 211 D-50, BW 211 DE-40, BW 211 PD-3, BW 211-40, BW 211 D-4i, BW 211 D-4 EU-Flex, BW 211 D-5 PL, BW 212 D-40, and BW 212 D-5 single drum rollers
- Full Compaction Force Restored — a worn or failed exciter unit causes loss of drum vibration, dramatically reducing compaction depth and output; replacing with a correctly specified unit restores full compactive effort
- Pre-Assembled for Efficiency — supplied as a complete assembled unit, eliminating the need to source and assemble individual internal components before installation
The exciter unit is the core vibratory mechanism inside a compaction drum. It uses an eccentric rotating mass driven by the drum's vibration motor to generate the centrifugal force that causes the drum to oscillate up and down, compacting soil or base material beneath it. When the exciter unit wears out or fails — through bearing failure, seal breakdown, or eccentric mass damage — the drum loses its vibration, and the roller becomes little more than a static deadweight roller, unable to achieve specified compaction depths or pass density requirements. Replacing the left exciter unit with a genuine Bomag part number 58002271 restores the drum's full vibratory output and ensures the machine meets compaction specification on the next pass.
