The Wacker Neuson Spacer Block is a genuine OEM component designed for the RD40-130 series tandem rollers, including the RD40-130, RD40-130 C, RD40-130 O, and their US-market variants. As a factory-sourced part, the is manufactured to the same tolerances and material specifications as the original, ensuring correct positioning and fit within the roller assembly. This Spacer Block covers a broad range of RD40-130 configurations — including standard, C, and O variants across multiple production revisions — so you can order with confidence that this is the right part for your machine.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to original Wacker Neuson tolerances, ensuring the spacer maintains correct component separation and alignment within the roller drivetrain.
- Drop-In Replacement — Matches original mounting geometry exactly, allowing straightforward installation without reworking adjacent components.
- Broad RD40-130 Series Coverage — Compatible with RD40-130, RD40-130 C, RD40-130 O, and US-market variants, as well as .3-revision models including the RD40-130.3, RD40-130c.3, and RD40-130o.3.
- Structural Integrity Under Load — A correctly fitted spacer block maintains proper component spacing under compaction loads; a worn or missing spacer can allow unwanted movement that accelerates wear on surrounding parts.
- Sourced Direct from Wacker Neuson — Genuine OEM designation means this part ships with the full backing of the Wacker Neuson parts program, with part number 5100011930 verified against current factory documentation.
A spacer block is a precision-machined component used to establish and maintain a fixed gap or offset between two mating parts within an assembly. In a tandem roller, spacer blocks are critical to keeping drivetrain or structural components correctly positioned relative to one another, preventing contact, misalignment, or excessive load transfer that could damage adjacent parts. When a spacer block wears down, cracks, or is missing entirely, it allows unintended movement between components — leading to accelerated wear, vibration, and potential mechanical failure if left unaddressed.
