The Wacker Neuson 1000015440 Washer ISO7089-20-200HV A2K is a genuine OEM component designed for the WL50 Articulated Wheel Loader. Sourced directly from Wacker Neuson, this washer is manufactured to the ISO 7089 standard for flat washers, ensuring correct load distribution and clamping performance at the fastener joints where it is specified. If you are servicing the cab-equipped WL50 and need a correctly rated replacement, part number 1000015440 is the confirmed OEM match.
Key Features
- ISO 7089 Standard Compliance: — Manufactured to the ISO 7089 flat washer specification in A2 stainless grade, delivering the corrosion resistance and hardness rating the WL50 design requires at this fastener location.
- 200HV Hardness Rating: — The 200HV designation confirms the washer meets the hardness value specified for high-load fastener assemblies, preventing embedment and maintaining correct clamp force over time.
- Direct OEM Replacement: — Drops into the existing fastener assembly without modification, matching the M20 nominal bore and seating geometry called out in the WL50 service documentation.
- WL50 Wheel Loader Fitment Confirmed: — Verified for the WL50 Articulated Wheel Loader (Cab) variant, so you can order with confidence that this is the correct part for your machine.
- Genuine Wacker Neuson OEM Quality: — As a genuine OEM part, 1000015440 is held to the same material and dimensional tolerances as the original production washer, protecting the integrity of the bolted joint it supports.
A flat washer serves a straightforward but important role in any bolted assembly: it distributes the clamping load of a fastener over a wider surface area, protecting the mating material from damage and maintaining consistent clamp force across the joint. In a machine like the WL50 Articulated Wheel Loader, where structural and drivetrain fasteners are subjected to vibration and cyclic loading during operation, using a washer of the correct grade and hardness is essential. A washer that is undersized, too soft, or incorrectly rated can allow fastener embedment or loosening over time, which may compromise the integrity of the assembly it secures.
