The Wacker Neuson Spacer Block is a genuine OEM component designed for the RD18-80, RD18-100, and RD18-100C series tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact dimensional and material specifications of the original, ensuring a correct fit without guesswork. It is compatible across a broad range of RD18 series configurations, including US and SE variants as well as the updated.3 series models.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the original Wacker Neuson specification, so the spacer block maintains the correct clearance and alignment geometry critical to roller drivetrain integrity.
- Direct Drop-In Replacement — Matches the original mounting points and profile of the 5100012006, allowing straightforward installation without reworking surrounding components.
- Broad RD18 Series Coverage — Fits RD18-80, RD18-100, and RD18-100C tandem rollers across standard, US, SE, and .3 series variants, covering a wide range of machines under a single part number.
- Structural Spacing Integrity — A correctly fitted spacer block keeps adjacent components properly separated and aligned; a worn or missing spacer can allow unwanted movement, accelerating wear on surrounding parts.
- Verified Part Number — Ordering by confirmed OEM part number 5100012006 eliminates the risk of receiving an incompatible part and keeps your machine on schedule.
A spacer block is a precision-fit structural component used to maintain a fixed gap or alignment between two adjoining parts within an assembly. In tandem roller applications, it ensures that rotating or load-bearing components stay correctly positioned relative to one another, preventing contact, misalignment, and uneven wear. When a spacer block degrades or is missing entirely, surrounding components can shift under load, leading to accelerated wear, vibration, or mechanical failure in the assembly it supports.
