The Wacker Neuson Serrated Washer is a genuine OEM serrated washer designed for the BL744ch, BL744h, BL744c, and BL744 EX Backhoe Loader series. As a direct Wacker Neuson OEM component, part is manufactured to the exact tolerances and material specifications required for these machines — no guesswork, no fitment concerns. This washer drops straight into place as a like-for-like replacement, making servicing fast and straightforward. If you're working on a BL744-series backhoe loader, this is the correct part to have on hand.
Key Features
- OEM-Spec Serration Profile — Manufactured with the precise tooth geometry and hardness required to grip and resist loosening under the load cycles typical of backhoe loader applications.
- Direct Drop-In Replacement — Matches the original washer's bore diameter, outer diameter, and serration pattern, seating correctly without modification to fastener assemblies.
- Confirmed Fitment for BL744 Series — Verified for the BL744ch, BL744h, BL744c, and BL744 EX Backhoe Loaders, covering multiple configurations within the BL744 family.
- Maintains Fastener Clamp Load — A correctly functioning serrated washer locks fasteners securely and prevents bolt loosening from vibration; a worn or missing washer risks joint failure and costly secondary damage.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, ensuring full part number traceability and consistency with the original machine build specification.
A serrated washer is a hardened fastening component with teeth or serrations on one or both faces that bite into the mating surfaces when a bolt or nut is torqued down. This locking action resists the rotational loosening caused by vibration and dynamic loads — conditions that are constant on a working backhoe loader. When a serrated washer becomes worn, flattened, or corroded, it loses its grip, allowing fasteners to back off over time, which can lead to joint movement, structural play, or component failure if left unaddressed.
