The Wacker Neuson 5100012186 is a genuine OEM Bow Plate designed for the RD40-130 and RD45-140 series tandem rollers. Sourced directly through Wacker Neuson's authorized parts network, this component meets the exact specifications of the original part installed at the factory. It is compatible across a wide range of RD40-130 and RD45-140 configurations, including standard, open-ROPS, canopy, and DPF-equipped variants. Confirming your machine's model number before ordering ensures a correct, direct fitment.
Key Features
- Genuine OEM Construction: — Manufactured to the same material grade and dimensional tolerances as the original, so the plate seats and fastens exactly as intended on the drum assembly.
- Broad RD-Series Coverage: — Fits the full RD40-130 and RD45-140 model families, including standard, open-ROPS (O/o), canopy (C/c), DPF, .3-revision, and US-market variants.
- Direct Bolt-On Replacement: — Designed to install in the original mounting position without modification, maintaining correct drum geometry and structural alignment.
- Structural Integrity on Every Pass: — A sound Bow Plate keeps the drum assembly properly positioned during compaction passes; a damaged or missing plate can allow drum deflection and uneven compaction patterns on asphalt or soil.
- Verified Part Number: — Order by part number 5100012186 to ensure you receive the correct plate for your RD40-130 or RD45-140 roller, not an approximation.
The Bow Plate is a structural component mounted at the curved forward section of the drum frame on Wacker Neuson tandem rollers. It reinforces the drum housing, helps maintain proper drum alignment, and protects adjacent components from impact and debris during compaction work. When the Bow Plate is cracked, bent, or missing, the drum can shift out of its designed operating position, leading to inconsistent compaction results and potential damage to surrounding components over time.
