The Wacker Neuson is a genuine OEM RD12 Exciter Manifold Assembly designed for RD12-90 and RD12A-90 series tandem rollers. Sourced directly from Wacker Neuson, this part carries the same engineering tolerances and material specifications as the original component it replaces. It fits multiple RD12-90 and RD12A-90 configurations, including solid ROPS and foldable ROPS variants, making it the correct choice whether you are working on a standard machine or a folding-ROPS model. When you need to restore the exciter system to full working order on your double-drum roller, part is the right call.
Key Features
- OEM-Matched Porting and Passages — Manufactured to the exact internal geometry of the original exciter manifold, ensuring correct hydraulic flow distribution to the drum vibration system.
- Drop-In Assembly Replacement — Designed to bolt directly into the exciter circuit on RD12-90 and RD12A-90 tandem rollers, aligning with existing hydraulic connections and mounting points without rework.
- Broad RD12 Series Coverage — Confirmed fitment across RD12-90 and RD12A-90 models in solid ROPS and foldable ROPS configurations, covering the full range of current RD12 walk-behind tandem roller variants.
- Restores Full Drum Vibration Output — A failed or leaking exciter manifold causes uneven or total loss of drum vibration, directly degrading compaction density. Replacing with 5000163345 brings vibration performance back to spec.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM assembly, verified under part number 5000163345, so you are installing a component built to the same standard as what left the factory.
The exciter manifold assembly is a central hydraulic component in the drum vibration system of a tandem roller. It directs pressurized hydraulic fluid from the machine's hydraulic circuit to the exciter motors that drive the eccentric weights inside each drum, generating the vibration force needed to compact asphalt or soil. When the manifold develops internal leaks, blockages, or damage, vibration output drops or stops entirely, leaving the roller unable to achieve the required compaction density — a critical problem on any paving or soil prep application. Replacing a worn or failed manifold with the correct OEM assembly restores consistent, full-amplitude drum vibration and gets the machine performing as intended.
