The Wacker Neuson is a genuine OEM Spacer Plate designed for the RD18-80, RD18-100, and RD18-100 C series tandem rollers. As a factory-original component, it meets the exact tolerances and material standards set during original production, ensuring a consistent, reliable fit within the roller assembly. This part covers a broad range of RD18 configurations including US and SE variants, as well as the RD18-80.3, RD18-100.3, and RD18-100c.3 model updates.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to the exact thickness and profile specifications required by the RD18 roller assembly, ensuring correct load distribution and spacing between mating components.
- Direct Drop-In Replacement — Matches the original mounting geometry of the RD18 series, so it seats correctly without modification to surrounding hardware or housings.
- Broad RD18 Series Coverage — Compatible with RD18-80, RD18-100, and RD18-100 C variants across standard, US, SE, and .3-series model generations.
- Structural Integrity Under Compaction Loads — A correctly fitted spacer plate maintains proper component alignment under the sustained vibration and compaction forces that tandem rollers generate, preventing accelerated wear on adjacent parts.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100012884 carries the same quality assurance as the original production component it replaces.
A spacer plate is a precisely dimensioned component used to set and maintain the correct gap or alignment between two mating parts within an assembly. In a tandem roller, correct spacing is critical to keeping drum drive and compaction components operating in proper alignment — misalignment caused by a worn or incorrect spacer can lead to uneven wear, vibration imbalance, or premature failure of surrounding parts. Replacing a damaged or out-of-spec spacer plate with the correct OEM part restores the intended geometry and protects the integrity of the wider assembly.
