Wacker Neuson 5000165402 Flat Washer .453 X 1.5 X .1875

The Wacker Neuson is a genuine OEM Flat Washer.453 X 1.5 X.1875 designed for the CT36 and CT48 series walk-behind concrete power trowels. As a factory-sourced component, part matches the original dimensions and material grade specified for these machines, ensuring a proper fit without adjustment or adaptation. Compatible models include the CT36-8A, CT36-9, CT48-8A, CT48-8A EU, CT48-9, and their corresponding variants. When a washer of incorrect sizing is used in its place, fastener clamp load and surface bearing area are compromised — replacing it with the correct OEM part keeps the assembly torqued and seated as intended.

Key Features

• Correct OEM Dimensions — Stamped to exact .453 x 1.5 x .1875 inch specifications, delivering the proper load-bearing surface area and clamp distribution required by the original fastener assembly.
• Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the same part number and material grade as the component installed at the factory.
• Broad CT-Series Fitment — Confirmed for CT36-8A, CT36-9, CT48-8A, CT48-8A EU, and CT48-9 walk-behind power trowels across multiple build variants.
• Drop-In Installation — Sized to seat correctly in the existing fastener stack without filing, shimming, or secondary machining.
• Fastener Integrity Under Vibration — A correctly sized flat washer distributes clamping force evenly across the mating surface, reducing fastener loosening caused by the continuous vibration inherent to concrete trowel operation.

A flat washer serves as the load-distributing interface between a fastener head or nut and the surface it clamps against. By spreading clamping force over a wider area, it prevents the fastener from pulling through or deforming the material beneath it and helps maintain consistent torque retention over time. On concrete power trowels — machines that run under sustained vibration and repeated loading — washers in critical assemblies are subject to gradual wear and fatigue; a washer that has deformed or worn thin will allow fastener preload to drop, leading to looseness in the assembly and accelerated wear on surrounding components.
