Wacker Neuson 5000117642 Washer 1-1/8 OD x .281 ID x .1875

The Wacker Neuson Washer 1-1/8 OD x.281 ID x.1875 is a genuine OEM component designed for the CRT36 and CRT48 series ride-on concrete trowels. As a factory-original part, is manufactured to the exact dimensional specifications required for proper load distribution and fastener seating in these machines. This washer fits an extensive range of CRT models including the CRT36-24A, CRT36-25, CRT36-26A, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, and CRT48-57K, among others. Sourcing the correct OEM part ensures the hardware stack-up remains within spec and the assembly performs as intended.

Key Features

• Exact OEM Dimensions — Manufactured to the precise 1-1/8 in. OD, .281 in. ID, and .1875 in. thickness called out in the Wacker Neuson parts system, ensuring correct load-bearing surface area under the fastener.
• Direct Drop-In Installation — Matches the original hardware configuration on CRT36 and CRT48 trowel assemblies, slipping onto the fastener shank without modification to the surrounding hardware stack.
• Broad CRT Series Coverage — Confirmed fitment across CRT36-24A, CRT36-25, CRT36-26A, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, CRT48-57K, and related variants including Power Steer and Dual-Fuel configurations.
• Fastener Integrity Under Vibration — A correctly sized washer distributes clamping load evenly and resists fastener back-out during the high-vibration operating cycles typical of ride-on concrete finishing work.
• Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, carrying the same part number 5000117642 referenced in the official service documentation for these trowel models.

A washer functions as a load-distribution interface between a fastener head or nut and the surface it bears against. By spreading clamping force across a larger area, it prevents the fastener from pulling through or deforming softer mating surfaces and helps maintain consistent preload in the joint. On ride-on concrete trowels, which generate continuous vibration during finishing passes, washers in critical assemblies are subject to constant micro-movement; using a washer with the correct outer diameter, inner diameter, and thickness keeps the joint tight and the assembly dimensionally stable over time. A missing or undersized washer can lead to fastener loosening, accelerated wear on the mating surface, and eventual joint failure.
