The Wacker Neuson Toothed Belt Pulley is a genuine OEM component designed for the RD24-100, RD27-120, RD40-130, and RD45-140 series tandem rollers. Sourced directly through Wacker Neuson's authorized parts network, this toothed belt pulley is manufactured to the exact dimensions and tooth profile required for proper drive belt engagement on these machines. Whether you're servicing a standard open-drum model or a DPF-equipped variant, part number covers an extensive range of configurations across both O-series and C-series rollers. Confirming this part number against your machine's serial number before ordering is always the best practice to ensure a direct fit.
Key Features
- OEM Tooth Profile Accuracy — Manufactured to the exact tooth geometry required for positive belt engagement, preventing slip, skipping, and premature belt wear on your roller's drive system.
- Direct-Fit Replacement — Matches the original mounting bore, hub dimensions, and pulley diameter so it seats and fastens exactly as the factory-installed unit does.
- Broad RD-Series Coverage — A single part number fits RD24-100, RD27-120, RD40-130, and RD45-140 tandem rollers across O-series, C-series, DPF, and .3-suffix configurations.
- Consistent Drive Timing — A worn or damaged toothed belt pulley causes erratic belt tension and timing loss; replacing it restores smooth, consistent power transfer to the drum drive.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM component, meaning the material grade and tooth hardness match the original specification for the intended service life.
A toothed belt pulley works together with a matching toothed drive belt to transfer rotational power from the engine or motor to the drum drive system in a tandem roller. The interlocking tooth profile is what makes this a positive-drive connection — unlike a smooth pulley, the teeth prevent belt slippage under load, which is critical for maintaining consistent drum speed and compaction output. When the pulley's teeth wear down, chip, or the bore becomes loose, belt tracking is compromised, leading to vibration, uneven compaction performance, and accelerated belt failure.
