The Wacker Neuson Spring Washer is a genuine OEM component designed for CRT48 and CRT36 series ride-on concrete trowels, as well as the BFS 1345K gasoline floor saw. Sourced directly from Wacker Neuson, this spring washer matches the original hardware specification used during factory assembly, ensuring a correct and consistent fit within the fastener stack. It is compatible with the CRT48-25K-L, CRT48-25K-H, CRT36-23K-H, and CRT36-25K-H models, covering both low-speed and high-speed ride-on trowel configurations. When replacing hardware on your machine, using the correct OEM spring washer — part number — helps maintain proper clamping force and connection integrity throughout the assembly.
Key Features
- OEM-Spec Temper and Tension: — Manufactured to the original spring rate and material hardness, maintaining the designed clamping force under vibration and thermal cycling common to trowel and saw operation.
- Drop-In Hardware Replacement: — Matches the original washer profile and inner diameter, seating correctly within the existing fastener stack without modification to surrounding components.
- Broad Fitment Across CRT Series and BFS 1345K: — Confirmed for CRT48-25K-L, CRT48-25K-H, CRT36-23K-H, and CRT36-25K-H ride-on trowels, plus the BFS 1345K gasoline floor saw.
- Vibration Resistance Built In: — The spring action of this washer continuously loads the fastener joint, resisting loosening caused by the sustained vibration that ride-on trowels and floor saws generate during operation.
- Genuine Wacker Neuson OEM Part: — Carries the Wacker Neuson OEM designation, meaning it is the same component used in original machine assembly — not an approximation of it.
A spring washer is a small but critical hardware component placed beneath a bolt or nut to maintain tension in a fastened joint. Its curved or split profile exerts a continuous spring load against the fastener, counteracting the loosening effect of vibration and dynamic loads. On ride-on concrete trowels and floor saws — machines that generate significant vibration during normal operation — spring washers play an important role in keeping structural and mechanical connections secure. A worn, deformed, or missing spring washer allows fasteners to back out gradually, which can lead to component misalignment, accelerated wear on adjacent parts, and potential mechanical failure if left unaddressed.
