The Wacker Neuson Spring is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including CT36 and CT48 walk-behind concrete power trowels, PT3A centrifugal trash pumps, BPU reversible vibratory plate compactors, BPS single-direction vibratory plate compactors, BFS floor saws, and G-series portable generators. Sourced directly from Wacker Neuson, this spring carries the same part number and specification as the original installed at the factory. It fits an extensive list of CT36 and CT48 trowel variants — including AGP, AGT, AVP, AVT, and ADP configurations — as well as PT3A pump models and multiple BPU 2950A, 3050A, 3545A, 4045A, and 3750Ats plate compactor variants. Cross-reference part number against your model and machine number before ordering to confirm compatibility with your specific unit.
Key Features
- Genuine OEM Tension and Rate Consistency — Manufactured to the exact spring rate and free-length specification of the original, ensuring correct mechanical response in every application this part serves.
- Drop-In Replacement — Matches the original mounting points and dimensional envelope, allowing straightforward installation without additional modification to surrounding components.
- Broad Cross-Family Fitment — A single part number covers CT36 and CT48 walk-behind trowels, PT3A trash pumps, BPU reversible plate compactors, BPS single-direction plates, BFS floor saws, and G-series generators — stock one part across multiple machines.
- Maintains Mechanical Preload — A spring at correct rate keeps linked components properly tensioned or returned to position; a fatigued or broken spring leads to inconsistent operation, chatter, or failure of the assembly it serves.
- Genuine Wacker Neuson Parts Sourcing — Supplied as genuine OEM, meaning the part number, material grade, and geometry are verified against Wacker Neuson's own bill of materials — not an estimate or approximation.
A spring stores and releases mechanical energy to maintain tension, return a component to its neutral position, or absorb shock within an assembly. Depending on the host machine, this spring may serve a throttle linkage, a clutch mechanism, a valve return, or another tensioned connection — in each case, keeping adjacent parts properly loaded and responsive. When a spring fatigues, takes a set, or breaks entirely, the component it controls can stick, float, or fail to return correctly, which affects operator control and can accelerate wear on surrounding parts.
