This part is the authoritative replacement for the BW 190 AD-4 AM, giving operators and service technicians confidence that they are installing the right component the first time.
Key Features
- Genuine OEM Precision — Manufactured to Bomag's original engineering tolerances for the exciter shaft, ensuring correct rotational balance and vibration output specific to the BW 190 AD-4 AM tandem roller.
- Direct-Fit Replacement — Matches the original shaft dimensions, spline profile, and mounting configuration for a straightforward drop-in installation.
- Verified Fitment — Confirmed fit for the BW 190 AD-4 AM tandem roller; part number 92027404 is the correct OEM reference for this machine.
- Consistent Compaction Output — A properly functioning exciter shaft maintains the drum's designed vibration frequency and amplitude, keeping asphalt compaction performance consistent and on-spec.
- Durable Construction — Built to withstand the continuous rotational stress and load cycles inherent to vibratory tandem roller operation, supporting extended service life between replacements.
The exciter shaft is the core rotating component inside the vibratory drum assembly. It is driven by the vibration motor and carries eccentric weights that generate the centrifugal force responsible for the drum's vibration. This vibration is what compacts asphalt or soil beneath the roller. When the exciter shaft wears, bends, or fails, the drum loses its vibratory action, resulting in uneven compaction, increased pass counts, and potential damage to surrounding drivetrain components. Replacing a worn shaft promptly restores full compaction capability and protects the integrity of the drum assembly.
