The Bomag 58010946 Assembled Left Exciter Unit is a genuine OEM component designed for BW 219 and BW 226 series single drum rollers, including the BW 219 DH-4, BW 219 PDH-4, BW 219 DH-4i, BW 219 DH-4i EU-Flex, BW 226 DH-4, BW 226 PDH-4, BW 226 DH-4i, and BW 226 DH-4i EU-Flex. Sourced directly from Bomag, this assembly matches the original unit in every dimension and specification, so installation is straightforward and alignment is correct from the start. When the exciter system is operating at full capacity, these heavy single drum rollers deliver the consistent compaction force that demanding soil and subbase work requires.
Key Features
- Genuine OEM Exciter Integrity — manufactured by Bomag to the same eccentric-weight balance and bearing specification as the original, preserving the drum's rated centrifugal force output
- Left-Side Direct Replacement — assembled and ready to install in the left exciter position, matching the mounting interface and shaft dimensions of the original unit
- Broad BW 219 and BW 226 Coverage — confirmed fit for BW 219 DH-4, BW 219 PDH-4, BW 219 DH-4i, BW 219 DH-4i EU-Flex, BW 226 DH-4, BW 226 PDH-4, BW 226 DH-4i, and BW 226 DH-4i EU-Flex single drum rollers
- Restored Compaction Performance — a worn or failed exciter unit causes uneven or insufficient compaction force; replacing it with part number 58010946 returns the drum to its specified amplitude and frequency
- Verified by Part Number 58010946 — cross-reference this number against your machine's parts manual before ordering to confirm you have the correct left-side assembly for your serial range
The exciter unit is the heart of a vibratory drum roller's compaction system. Mounted inside the drum shell, it uses rotating eccentric weights to generate the high-frequency vibration that drives compaction force into the ground. The left exciter unit works in coordination with the right-side unit to produce balanced, consistent amplitude across the full drum width. When this assembly wears, loses a bearing, or suffers internal damage, vibration output drops or becomes erratic — leaving lifts undercompacted and forcing costly rework. Replacing the Assembled Left Exciter Unit with a genuine Bomag part restores the drum to its original dynamic balance and rated performance.
