The Wacker Neuson is a genuine OEM Flat Steel Washer designed for a broad range of Wacker Neuson equipment, including CRT36 and CRT60 ride-on concrete trowels, HI Series indirect-fired air heaters, APT Series pumps, and vibratory screed sections. As a direct factory replacement, this washer meets the original design specifications set by Wacker Neuson for every application it serves. Part number is a high-volume fastener component used across multiple machine families, making it a smart stocking item for dealers, rental fleets, and service technicians. Confirm your model number against the fitment list before ordering to ensure this is the correct washer for your application.
Key Features
- Genuine OEM Steel Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the correct load distribution and clamping force for each fastened joint.
- Drop-In Replacement — Matches the original hole diameter, outer diameter, and thickness exactly, so it seats against mating hardware without shimming or adjustment.
- Wide Fitment Coverage — Compatible with CRT36 and CRT60 ride-on trowels, HI260, HI750, and HI900 indirect air heaters, APT4T, APT6T, and APT8T pumps, LTC4L light towers, and HC/HE/SE screed sections.
- Prevents Joint Failure — A correctly spec'd washer distributes clamping load evenly across the mating surface; an undersized or worn washer can allow fasteners to loosen under vibration, leading to structural or mechanical joint failure.
- High-Volume Service Item — Used across dozens of Wacker Neuson machine variants, making this a practical part to keep on the shelf for routine maintenance and field repairs.
A flat steel washer serves as a load-spreading interface between a fastener — bolt head or nut — and the surface it bears against. By distributing clamping force over a larger contact area, it prevents the fastener from pulling through or deforming softer materials and maintains consistent joint tension over time. In equipment that operates under continuous vibration, such as concrete trowels and indirect-fired heaters, even a small washer plays a critical role in keeping assemblies torqued correctly; a missing or incorrect washer can allow fasteners to back out, causing component misalignment or premature wear at the joint.
