The Wacker Neuson Double Torsion Spring is a genuine OEM component designed for the CT36 and CT48 series walk-behind concrete power trowels. This spring is sourced directly from Wacker Neuson, ensuring exact dimensional and material compliance with the original specification. It fits a wide range of CT36 and CT48 configurations, including gas-powered, diesel-powered, electric, variable-speed, and CE-compliant variants across both 915mm/36in and 1220mm/48in trowel sizes. When you order by part number, you can be confident you are receiving the correct part for your machine.
Key Features
- Genuine OEM Torsion Rating — Manufactured to the original spring rate and geometry, maintaining correct engagement tension throughout the trowel's operating cycle.
- Direct Drop-In Replacement — Matches the factory mounting configuration on CT36 and CT48 trowels, fitting into the existing spring seat without alteration.
- Broad CT Series Coverage — Compatible with CT36 and CT48 models in gas (AGP), diesel (ADP), electric (E), and variable-speed (AVP) configurations, including CE-certified variants.
- Consistent Blade Pitch Control — A correctly tensioned torsion spring maintains steady resistance through the pitch adjustment linkage, keeping blade angle uniform across the trowel head for an even concrete finish.
- Double-Wound Design — The double torsion construction distributes rotational load across two coil sections, extending service life under the repetitive stress cycles common in concrete finishing work.
The double torsion spring plays a direct role in the blade pitch adjustment mechanism of the CT-series walk-behind trowel. It provides the return force that keeps the pitch control linkage under tension, allowing the operator to precisely change the angle of the finishing blades during operation. When this spring fatigues, loses tension, or breaks, blade pitch control becomes inconsistent or unresponsive, which results in an uneven surface finish and increased operator effort. Replacing a worn spring restores the responsive, predictable blade control that concrete finishing work demands.
