As a genuine Wacker Neuson OEM component, the is manufactured to the exact material and dimensional specifications of the original seal, ensuring a proper sealing surface and consistent service life. Keep one on the shelf — this seal covers a broad cross-section of the WP and VP compactor lineup and is a common item in preventive maintenance routines.
Key Features
- Genuine OEM Sealing Material — Manufactured to Wacker Neuson's original compound and lip geometry specifications, delivering the compression and wear resistance required in high-vibration compaction applications.
- Direct Drop-In Fitment — Sized and profiled to seat correctly in the original bore, with no machining or adaptation needed to install in the shaft housing.
- Broad Model Coverage — Fits the WP1540A, WP1540Aw, WP1550A, WP1550Aw, VP1340A, VP1340Aw, VP1550A, VP1550Aw, VP2050A, and VP2050Aw vibratory plate compactors across multiple production variants.
- Prevents Gear Oil Contamination — A correctly functioning rotary shaft seal keeps exciter housing lubricant contained and blocks soil, water, and debris from entering the drive assembly — protecting gears and bearings from accelerated wear.
- OEM Part Number Confidence — Sold under Wacker Neuson part number 5100016446, cross-referenced across a wide range of WP and VP production series so you can order with confidence.
The rotary shaft seal sits at the interface between the rotating exciter shaft and the exciter housing on a vibratory plate compactor. Its job is to retain the gear oil inside the exciter assembly while preventing contaminants — dirt, water, and fine aggregate — from migrating inward along the shaft. When this seal wears or fails, oil leaks from the exciter housing and external debris enters the drive system, leading to rapid deterioration of the gears and bearings that generate the plate's compaction force. Replacing a worn seal promptly with the correct OEM part is one of the most cost-effective ways to protect the exciter assembly and maintain consistent compaction performance on the job.
