The Wacker Neuson Washer 8.4 Type A is a genuine OEM component designed for the RD11AEC and RD11A hydrostatic double drum vibratory rollers. Sourced directly from Wacker Neuson, this washer meets the exact dimensional and material specifications of the original part installed at the factory. It is a direct-fit replacement for the RD11 series tandem rollers, ensuring proper seating and load distribution across the fastened joint. Keep a spare on hand to avoid delays during scheduled maintenance or field repairs on your roller.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact 8.4 mm bore specification, ensuring correct bearing surface contact and consistent clamping load across the fastened joint.
- Type A Profile — The Type A flat washer geometry provides full, even load distribution under the fastener head, preventing surface damage and fastener loosening during high-vibration roller operation.
- Direct Fit for RD11 Series Rollers — Confirmed fitment for the RD11AEC and RD11A hydrostatic double drum vibratory rollers; drops into place with no modification to the existing hardware assembly.
- Vibration-Rated Durability — Built to withstand the continuous vibration loads generated by double drum compaction cycles, resisting deformation and fretting that can cause premature fastener failure.
- OEM Part Confidence — As a genuine Wacker Neuson part, the 5000115584 carries the correct part number traceability for service records, warranty documentation, and repeat ordering.
A washer distributes the clamping force of a bolt or nut across a wider surface area, protecting the material beneath the fastener head and maintaining consistent joint tension. In a high-vibration machine like a double drum vibratory roller, washers play a critical role — without proper load distribution, fasteners can work loose or the mating surface can deform over time, leading to joint failure during operation. Using the correct washer size and type, such as this 8.4 Type A, ensures the hardware assembly holds to specification through demanding compaction cycles.
