The Bomag 92020519 Exciter Unit is a genuine OEM component designed for Bomag tandem rollers across the BW 141, BW 151, BW 161, BW 170, BW 174, BW 190, BW 202, BW 203, and BW 205 series, including models BW 161 AD-4, BW 202 AD-4, BW 174 AD-2 AM, BW 174 AD-2, BW 141 AD-4, BW 174 AC-2. Sourced directly from Bomag, this exciter unit meets the original engineering standards set for these tandem rollers, ensuring the drum delivers the compaction force your application demands. This unit is a direct-fit replacement for all confirmed compatible models, including AM variants, EU-Flex configurations, and AC/AP drum variants listed in the fitment data.
Key Features
- Genuine OEM Vibration Engineering — manufactured to Bomag's original eccentric-weight and bearing specifications, so the drum produces the correct centrifugal force and amplitude for asphalt compaction work
- Direct-Fit Replacement — engineered to mount into the drum assembly exactly as the original unit, with matching bolt pattern and shaft interface for a straightforward swap
- Broad Tandem Roller Coverage — confirmed fitment across BW 141, BW 151, BW 161, BW 170, BW 174, BW 190, BW 202, BW 203, and BW 205 tandem rollers, including AD, AC, AP, ADH, and ADO drum variants
- Restored Compaction Output — a worn or failed exciter unit causes loss of drum vibration, leading to under-compacted mat and costly rework; this replacement restores full vibratory output so the machine performs to spec
- Verified Part Number Fitment — order with confidence using Bomag part number 92020519, cross-referenced to the specific tandem roller models and configurations in Bomag's OEM catalog
The exciter unit is the heart of a vibratory drum — it houses the eccentric weights and bearings that convert rotational energy from the drum drive into the oscillating compaction force that densifies asphalt and granular material. When the exciter unit is functioning correctly, the drum delivers consistent amplitude and frequency, producing a tight, stable mat surface. When the unit fails — through bearing wear, seal breakdown, or eccentric weight damage — vibration is lost entirely or becomes erratic, leaving the roller unable to achieve target density and forcing operators to make additional passes or accept substandard compaction results.
