The Wacker Neuson 5100004545 is a genuine OEM Exciter Complete (DPU80r) designed for DPU80r and DPU90r series reversible vibratory plate compactors. As a direct OEM replacement sourced through the Wacker Neuson parts network, the 5100004545 is manufactured to the same specifications as the original unit — ensuring correct eccentric mass, bearing fit, and housing geometry. This exciter assembly is confirmed to fit the DPU80rLec670, DPU80rLec770, DPU80rLem670, DPU80rLem770, DPU90rLec770 US, DPU90rLem770 US, and the DPU 80/110 KMAT vibration plate platform. Installing a correctly matched exciter assembly is critical to restoring the compaction force and operational characteristics the machine was built to deliver.
Key Features
- Genuine OEM Eccentric Precision — Manufactured to the original eccentric mass specification, ensuring the compaction force output matches the machine's engineered performance ratings.
- Drop-In Housing and Bearing Fit — Replaces the original exciter assembly with matching bolt pattern, shaft dimensions, and bearing seats — no machining or adaptation needed.
- Broad DPU80r and DPU90r Coverage — Fits multiple Lec and Lem engine configurations across the DPU80r and DPU90r families, as well as the DPU 80/110 KMAT platform.
- Restores Full Compaction Force — A worn or failed exciter reduces vibration amplitude and frequency, leaving soil and aggregate under-compacted. A fresh assembly brings the plate back to its rated output.
- Fuel System and Drive Independence — Compatible across both Lec (electric-start) and Lem (manual-start) engine variants, making this a versatile stock item for fleet operators running mixed DPU80r configurations.
The exciter assembly is the core vibration-generating unit of a reversible vibratory plate compactor. It contains an eccentric weight mechanism driven by the engine that produces the rapid oscillating force transferred through the base plate into the ground — compacting soil, aggregate, or granular fill to the required density. In reversible plate compactors like the DPU80r and DPU90r, the exciter also controls the direction of travel by shifting the phase of the eccentric weights. When the exciter wears out or fails, the machine loses compaction efficiency, may become difficult to steer, or stops moving altogether — making timely replacement essential to keeping the compactor performing at its rated capacity.
