The Wacker Neuson Exciter Complete is a genuine OEM component designed for WP1540A, WP1540Aw, WP1550A, and WP1550Aw single-direction vibratory plate compactors. As a direct OEM replacement, this exciter assembly is manufactured to the same specifications as the original unit, ensuring correct eccentric weight geometry, shaft tolerancing, and housing fit. Confirmed fitment spans both standard and US-market variants of the WP1540A and WP1550A series, as well as CN-market and Sunbelt-distributed WP1550Aw machines. When your compactor loses vibratory force or develops vibration irregularities, the Exciter Complete is the factory-correct solution to restore full compaction output.
Key Features
- Factory-Correct Eccentric Weight Assembly — Genuine OEM construction ensures the eccentric weight mass and balance match original design parameters, delivering the correct centrifugal force output your plate compactor depends on.
- Direct Housing and Shaft Compatibility — The exciter unit is engineered to mount directly into the baseplate housing of WP1540A, WP1540Aw, WP1550A, and WP1550Aw machines without modification to mounting points or drive connections.
- Broad WP Series Fitment — Covers standard, US-market, CN-market, and Sunbelt-distributed variants across the WP1540A and WP1550A model families, making this a versatile stocking part for fleet operators and rental yards.
- Restores Full Compaction Force — A worn or seized exciter results in reduced amplitude and uneven surface compaction. Replacing it with part 5100016322 brings vibration frequency and amplitude back to spec, so the plate performs correctly on soil, aggregate, and paving stone applications.
- Sealed for Operational Durability — The complete exciter assembly is built to withstand the continuous rotational loads and vibration stress inherent to single-direction plate compactor operation, supporting consistent output over extended service intervals.
The exciter is the heart of a vibratory plate compactor's compaction system. It consists of a housing containing one or more eccentric weights mounted on a rotating shaft, driven by the engine via a centrifugal clutch. As the shaft spins, the offset weights generate centrifugal force that causes the baseplate to vibrate rapidly against the ground surface, densifying the material below. If the exciter bearings wear, the shaft seizes, or the housing cracks, the plate loses its vibratory action entirely or produces weak, inconsistent compaction — leaving surfaces under-compacted and failing to meet density requirements. Replacing the full exciter assembly as a complete unit restores proper amplitude and ensures all internal components are correctly matched and pre-assembled.
