The Wacker Neuson is a genuine OEM Eccentric Weight designed for the BPU 3545A and BPU 3545A US reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this part matches the original component in mass, geometry, and balance — the critical factors that determine how much compaction force the machine delivers. It is a direct replacement for worn or damaged eccentric weights on 35 kN class BPU compactors, and fits both the standard and US-market variants of the BPU 3545A platform.
Key Features
- Calibrated Mass and Balance: — Manufactured to the exact weight and dimensional tolerances of the original, ensuring the exciter assembly generates the correct centrifugal compaction force on reinstallation.
- Genuine OEM Part: — Supplied by Wacker Neuson under part number 5000126631, so you receive the same component that left the factory — no substitutions, no guesswork.
- Direct Fitment for BPU 3545A Series: — Compatible with the BPU 3545A and BPU 3545A US reversible vibratory plate compactors; slots into the existing exciter housing without modification to mounts or fasteners.
- Restores Full Compaction Output: — A worn or out-of-spec eccentric weight reduces centrifugal force, leaving soil or aggregate under-compacted. Replacing it returns the machine to its rated 35 kN performance.
- Vibration System Integrity: — Correct eccentric weight spec protects surrounding exciter components — bearings, shaft, and housing — from the uneven loading caused by an imbalanced or underweight rotor.
The eccentric weight is the core of a vibratory plate compactor's exciter system. As it rotates at high speed inside the exciter housing, its offset mass generates centrifugal force, which drives the rapid vibration that compacts soil, aggregate, and base material beneath the plate. On a reversible plate like the BPU 3545A, paired eccentric weights also control travel direction by shifting their relative phase. When an eccentric weight loses mass through wear, cracking, or impact damage, the machine produces less compaction force than rated, and the remaining drivetrain components must absorb the imbalance — accelerating bearing and shaft wear. Replacing the weight promptly with a correctly specified OEM part restores both compaction performance and drivetrain balance.
