The Wacker Neuson Rotary Shaft Seal is a genuine OEM rotary shaft seal designed for the DPU6555, DPU5545, DPU4545, and RD7H series reversible plate compactors. Sourced directly from Wacker Neuson, this seal matches the original component specification for a direct, hassle-free installation. Confirmed fitment spans a wide range of DPU and RD7H variants, making a reliable go-to replacement for operators running these machines in demanding compaction work.
Key Features
- Genuine OEM Sealing Material — Manufactured to Wacker Neuson's original material grade and compression specification, ensuring the seal performs under the rotational stress and heat cycles typical of heavy-duty plate compactor operation.
- Direct-Fit Replacement — Engineered to the exact dimensional profile of the original, so the seal seats correctly against the shaft and housing without rework or shimming.
- Broad DPU & RD7H Series Coverage — Compatible with DPU6555, DPU5545, and DPU4545 variants as well as RD7H and RD7Hf models, covering a large portion of Wacker Neuson's reversible plate compactor lineup.
- Prevents Fluid Loss at the Shaft — A correctly functioning rotary shaft seal keeps exciter oil contained within the drive assembly, protecting internal components from contamination and oil starvation.
- OEM Part Number Assurance — Ordering under part number 5100051916 confirms you are receiving the exact Wacker Neuson-authorized component, eliminating guesswork when cross-referencing multiple DPU model variants.
A rotary shaft seal sits at the point where a rotating shaft exits a housing, creating a dynamic barrier that prevents lubricating oil from leaking out while blocking dirt, water, and debris from entering. On Wacker Neuson plate compactors, this seal is critical to maintaining the integrity of the exciter unit — the assembly responsible for generating the vibration force that drives soil compaction. When the seal wears or hardens with age, oil escapes the housing, internal components run dry, and bearing and gear wear accelerates rapidly, often leading to costly exciter unit failure.
