The Bomag 88023605 Exciter Shaft is a genuine OEM component designed for BW 120 AD-4, BW 120 AC-4, and BW120AD 4 tandem rollers. Sourced directly from Bomag, this exciter shaft matches the original part in every dimension and material specification, ensuring it seats correctly within the drum's vibration assembly without rework or adaptation. If your tandem roller has lost amplitude, it is producing uneven compaction, or is showing signs of vibration system wear, this is the OEM-grade shaft your machine calls for.
Key Features
- Genuine OEM Shaft Integrity — Manufactured to Bomag's original tolerances for the exciter assembly, ensuring proper eccentric weight alignment and consistent vibration output across the drum.
- Direct OEM Replacement — Engineered to install into the drum vibration housing of BW 120 AD-4, BW 120 AC-4, and BW120AD 4 tandem rollers using the same mounting configuration as the original shaft.
- Verified Tandem Roller Fitment — Confirmed compatibility across the BW 120 AD-4, BW 120 AC-4, and BW120AD 4 tandem roller platforms, so you can order with confidence.
- Sustained Vibration Performance — A correctly functioning exciter shaft maintains the drum's vibration frequency and amplitude, delivering the compaction force your asphalt passes require. A worn or damaged shaft causes irregular vibration, poor mat density, and accelerated bearing wear throughout the exciter assembly.
- Exact Part Number Match — Ordering by Bomag part number 88023605 confirms you are receiving the correct shaft — not a near-fit substitute — for your BW 120-series tandem roller.
The exciter shaft is the central rotating component inside the drum's vibration system. It carries eccentric weights that, when spun at operating speed, generate the centrifugal force that causes the drum to vibrate against the surface being compacted. On tandem rollers like the BW 120 series, this controlled vibration is what drives aggregate interlock and achieves target mat density on asphalt applications. When the exciter shaft wears, bends, or fails, vibration becomes erratic or stops entirely — leaving the roller functioning only in static mode, which significantly reduces compaction effectiveness and can lead to costly mat rework.
