The Wacker Neuson Wave Stack Spring is a genuine OEM component designed for CT36 and CT48 series walk-behind concrete power trowels. This spring is sourced directly from Wacker Neuson, ensuring it meets the original engineering specifications for your machine. It is compatible across a broad range of CT36 and CT48 configurations, including gas-powered, diesel-powered, electric-drive, and variable-speed models in both standard and CE variants. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Spring Tension: — Manufactured to the original wave-stack spring rate, so the blade pitch mechanism responds consistently across the full range of trowel settings.
- Drop-in Replacement: — Matches the original mounting geometry and stacking configuration, allowing straightforward installation without modification to surrounding components.
- Broad CT-Series Fitment: — Covers CT36 and CT48 walk-behind trowel families, including AGP, ADP, AGP-E, ADP-E, and AVP variants in both standard and CE-certified configurations.
- Restores Blade Pitch Control: — A worn or fatigued wave spring causes inconsistent blade pitch and uneven finishing pressure; replacing it restores smooth, predictable surface control.
- OEM Part Number Assurance: — Part number 5000111638 is the authorised Wacker Neuson reference, eliminating guesswork when cross-referencing your machine's parts diagram.
The wave stack spring is a critical component in the blade pitch adjustment assembly of a walk-behind concrete power trowel. It provides controlled resistance and return force as the operator adjusts blade angle, ensuring smooth and even engagement across all finishing blades. When this spring fatigues, loses tension, or breaks, blade pitch becomes erratic or unresponsive, which directly affects the quality of the finished concrete surface and can place additional stress on the pitch adjustment mechanism.
