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. As a direct OEM part, the is manufactured to the exact dimensions and tooth profile required for correct belt engagement and tension in these machines. This part covers a broad range of RD-series configurations including O, C, DPF, and.3 variants across both US and international builds, making it a single reliable solution for fleets running multiple roller spec levels. When your drive system needs attention, specifying the correct toothed belt pulley keeps your compaction equipment performing as intended.
Key Features
- Exact Tooth Profile Geometry — Manufactured to OEM tooth form so the drive belt seats, tracks, and transfers torque without slipping or accelerated belt wear.
- Direct OEM Replacement — Part number 5100011689 matches the original pulley's bore, hub, and belt pitch, dropping straight into place with no machining or shimming required.
- Broad RD-Series Coverage — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across O, C, DPF, and .3 model variants in both US and international configurations.
- Sustained Drive Efficiency — A correctly sized pulley maintains proper belt tension and alignment, preserving smooth, consistent power delivery to the compaction drum.
- Genuine Wacker Neuson OEM Quality — Sourced directly through the Wacker Neuson parts network, ensuring the material grade and dimensional tolerances match what left the factory originally.
A toothed belt pulley is a toothed sprocket-style wheel that meshes with a matching toothed drive belt to transfer rotational power from the engine or motor to driven components — in the case of these tandem rollers, typically the drum drive or auxiliary systems. Unlike smooth V-belt pulleys, the interlocking tooth profile prevents belt slip under load, which is critical for maintaining consistent drum speed and compaction output. When the pulley teeth wear down or the pulley runs out of true, the belt can skip, vibrate, or fail prematurely, resulting in erratic drum performance or a complete loss of drive.
