The Wacker Neuson is a genuine OEM Exciter Manifold Assembly designed for the RD12A-90 series tandem rollers, including the standard RD12A-90 Tandem Roller and the RD12A-90 Tandem Roller with Foldable ROPS. As a direct Wacker Neuson OEM part, the is manufactured to the exact specifications of the original component — ensuring a straight-in installation with no guesswork on routing, porting, or hardware alignment. If your RD12A-90 roller is showing inconsistent vibration output or loss of exciter function, this assembly is the correct OEM solution to restore it to proper working order.
Key Features
- OEM-Matched Porting and Sealing Surfaces — Manufactured by Wacker Neuson to match the original exciter manifold geometry, ensuring correct fluid flow paths and leak-free connections within the exciter system.
- Direct Drop-In Replacement — Bolt pattern, port sizing, and assembly dimensions mirror the original unit, so installation follows the same procedure as the factory-fitted component.
- Confirmed Fitment for RD12A-90 Variants — Compatible with the standard RD12A-90 Tandem Roller, the RD12A-90 Double Drum Roller, and the RD12A-90 Tandem Roller with Foldable ROPS.
- Restores Full Exciter Performance — A failed or leaking exciter manifold disrupts vibration amplitude and compaction consistency. This assembly brings the exciter circuit back to spec so the drum delivers the compaction force the machine is rated for.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5100043965 carries the same material and build standards as the component it replaces.
The exciter manifold assembly is a core hydraulic component within the roller's vibration system. It directs pressurized hydraulic fluid to and from the exciter motor that drives drum vibration — the force responsible for compacting soil, asphalt, and subbase material. When this manifold cracks, leaks, or becomes blocked, hydraulic pressure to the exciter motor drops, leading to weak or absent drum vibration and poor compaction results. Replacing a worn or damaged manifold assembly restores the correct flow and pressure the exciter system needs to operate at full efficiency.
