The Wacker Neuson is a genuine OEM Zinc Cotter Pin.0585X1-1/8 designed for the RD12A-90, RD12-90, and RD11 series tandem rollers. Sourced directly from Wacker Neuson, this cotter pin meets the exact dimensional and material standards specified for these double-drum vibratory rollers. It is a direct replacement for the original hardware, requiring no modification to fit. Confirmed fitment spans both solid and foldable ROPS configurations of the RD12 series, as well as the RD11A and RD11V hydrostatic double-drum models.
Key Features
- Genuine OEM Zinc Construction — The zinc coating provides corrosion resistance suited to the wet and abrasive environments tandem rollers regularly operate in, maintaining fastener integrity over time.
- Exact Dimensional Match — At .0585 x 1-1/8 inches, this pin matches the original specification, seating correctly in the retaining hole without play or modification.
- Broad RD Series Compatibility — Fits RD12A-90 (standard and foldable ROPS), RD12-90 (solid and foldable ROPS), RD11A, and RD11V double-drum vibratory roller models.
- Retains Critical Hardware Under Vibration — Tandem rollers generate continuous vibration during operation; a correctly fitted cotter pin prevents fastener migration and keeps pinned connections locked in place during compaction passes.
- Safety-Critical Fastener — Cotter pins secure load-bearing and structural pinned joints; using an OEM-specification replacement ensures the locking mechanism performs as designed and does not shear or back out under load.
A cotter pin is a small but essential locking fastener used to secure clevis pins, axle pins, and other cylindrical fasteners in place, preventing them from working loose under vibration or movement. On double-drum tandem rollers like the RD12 and RD11 series, pinned connections appear throughout the steering linkage, ROPS hardware, and auxiliary attachment points — all areas subject to constant mechanical stress. When a cotter pin fails or goes missing, the pin it secures can migrate out of position, leading to loose joints, loss of steering control, or structural movement that accelerates wear on surrounding components.
