The Wacker Neuson is a genuine OEM Toothed Belt Pulley designed for the RD24-100, RD27-120, RD40-130, and RD45-140 series tandem rollers. As a factory-sourced component, the is manufactured to the same specifications as the original part it replaces, ensuring a correct interface with the toothed drive belt and surrounding drivetrain components. This pulley covers a broad range of RD-series configurations including O, C, and US-market variants, making it the dependable choice when restoring belt drive function on your roller.
Key Features
- Genuine OEM Tooth Profile: — Manufactured with the same tooth geometry as the original, maintaining proper belt mesh and eliminating slippage under load.
- Direct-Fit Installation: — Engineered to match the original shaft bore and bolt pattern, allowing the pulley to seat and align correctly without machining or modification.
- Broad RD-Series Compatibility: — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across O, C, and US-market configurations.
- Preserves Belt Drive Efficiency: — A correctly sized and properly toothed pulley keeps belt tension consistent and power transfer smooth, protecting both the belt and the driven components it serves.
- Wacker Neuson Authorized Part: — Sourced directly from Wacker Neuson, so the part number, dimensions, and material grade match what came off the assembly line.
A toothed belt pulley transmits rotational power from the engine or motor to downstream drivetrain components by meshing precisely with the teeth of a synchronous drive belt. Unlike a smooth pulley, the toothed design locks the belt in place mechanically, preventing slip and ensuring the driven shaft turns in exact ratio to the driving source — critical for maintaining consistent drum rotation and compaction performance on a tandem roller. When the pulley wears, chips, or the tooth profile becomes rounded, the belt begins to skip or jump, causing erratic drum movement, accelerated belt wear, and ultimately a loss of compaction force that can affect the quality of the finished surface.
