The Wacker Neuson is a genuine OEM Washer 5/16 Flat designed for CRT36 and CRT46 series ride-on concrete trowels, as well as the GS5.5A portable generator. As a direct factory replacement, part meets the original engineering specification for load distribution and surface protection on the fastener assemblies where it is used. This washer is confirmed compatible with the CRT46KHN, CRT46KHO, CRT46ASO, CRT36ASO, and CRT36ASN models, as well as the GS5.5A generator. Ordering by the correct part number ensures you receive the exact flat washer specified for these machines.
Key Features
- Genuine OEM Material Grade — manufactured to the original dimensional and material specification, ensuring correct load-bearing surface area for the fastener joints where this washer is installed.
- Drop-In Replacement — matches the original 5/16 flat profile exactly, seating against mating hardware without rework or shimming.
- Broad CRT Series Fitment — confirmed for the CRT36ASO, CRT36ASN, CRT46KHN, CRT46KHO, and CRT46ASO ride-on trowel models, as well as the GS5.5A portable generator.
- Protects Mating Surfaces — distributes fastener clamp load evenly, preventing surface damage, fastener pull-through, and loosening under vibration during trowel or generator operation.
- Sourced Direct from Wacker Neuson — supplied through the authorized Wacker Neuson parts channel under part number 5000083903, so the specification is traceable back to the original design.
A flat washer serves a straightforward but important role: it spreads the clamping force of a bolt or nut across a wider surface area, protecting the material beneath and keeping the fastener assembly tight under load. On ride-on concrete trowels like the CRT36 and CRT46 series, where vibration and rotational forces are constant during finishing operations, a correctly fitted washer helps maintain joint integrity and prevents hardware from working loose over time. A missing or incorrect washer can lead to fastener damage, accelerated wear on the surrounding material, and eventual mechanical loosening that affects both performance and safe operation of the machine.
