The Wacker Neuson Retainer Washer is a genuine OEM component designed for the CRT36 and CRT46 series ride-on concrete power trowels, including the CRT36ASO, CRT36ASN, CRT46ASO, CRT46KHN, and CRT46KHO models. As a direct factory replacement, part is produced to the same specifications as the original hardware installed at the time of manufacture. Drop-in installation means no fitting, grinding, or modification — the washer seats and retains exactly as intended. Keep a spare on hand and you'll be back to finishing concrete without delay.
Key Features
- Genuine OEM Hardware Integrity — Manufactured by Wacker Neuson to the exact dimensional tolerances of the original, ensuring correct clamping load and retention without distortion or creep.
- Direct Factory Replacement — Part number 5000087905 matches the original fitment position, seating flush and retaining securely without any rework to the mounting area.
- Broad CRT Series Coverage — Confirmed fitment across the CRT36ASO, CRT36ASN, CRT46ASO, CRT46KHN, and CRT46KHO ride-on concrete trowel models.
- Sustains Proper Assembly Retention — A correctly functioning retainer washer holds mating components in their designed position; a worn or missing washer allows movement, accelerating wear on surrounding hardware and adjacent assemblies.
- Genuine OEM Sourcing — Sourced directly through the Wacker Neuson parts network, so the part number, fitment, and material grade are exactly as documented in the OEM parts catalog.
A retainer washer is a load-distributing fastener component that sits between a bolt or nut and the surface it secures, spreading clamping force evenly and preventing the fastener from pulling through or damaging the mating material. On a ride-on concrete trowel like the CRT36 and CRT46 series, these washers are used throughout the machine wherever consistent retention and vibration resistance are critical to keeping assemblies tight under continuous operating loads. When a retainer washer deforms, corrodes, or goes missing, fastener preload drops, hardware loosens over time, and the components it was meant to secure become susceptible to premature wear or failure.
