Wacker Neuson 5100012212 Washer — Genuine OEM for RD Series Tandem Rollers

The Wacker Neuson Washer is a genuine OEM replacement built for the RD18, RD24, RD27, RD28, RD40, and RD45 series tandem rollers. Sourced directly from Wacker Neuson, this washer matches the original component specification so it seats and functions exactly as the factory intended. The covers an extensive range of RD series configurations — including standard, C, O, DPF, and electric variants — making it a go-to service part for fleet operators and dealers alike. Cross-reference your model number against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Dimensioning — Manufactured to the exact thickness, inner diameter, and surface finish specified by Wacker Neuson, ensuring correct load distribution at the fastened joint.
• Drop-In Installation — Designed to seat directly onto the original fastener or shaft without reworking the mating surfaces, keeping service time to a minimum.
• Broad RD Series Coverage — Fits RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers across standard, C (combination), O (offset), DPF, and electric configurations in both US and international variants.
• Maintains Clamping Integrity — A correctly spec'd washer distributes fastener load evenly across the mating surface, preventing housing deformation and bolt loosening under the sustained vibration of compaction work.
• Authorized Wacker Neuson Part — Part number 5100012212 is sourced through authorized supply channels, so you receive the same component installed at the factory — not a substitute grade.

A washer performs a straightforward but essential job: it spreads the clamping force of a bolt or nut across a wider surface area, protecting the material beneath from damage and keeping the fastened assembly from working loose over time. On compaction equipment like tandem rollers — which operate under constant vibration and load cycling — washers take on added importance because even minor loosening at a fastened joint can accelerate wear on surrounding components or allow critical assemblies to shift out of alignment. Replacing a worn, deformed, or missing washer with the correct OEM part restores proper clamping force and helps prevent more costly secondary damage down the line.
