The Wacker Neuson 5100012594 is a genuine OEM Flange designed for the RD40-130 and RD45-140 series tandem rollers. As a direct factory replacement, this flange is sourced and manufactured to the same specifications as the original component installed at the factory. Fitment spans a wide range of RD40-130 and RD45-140 configurations, including standard, offset, combination, and DPF-equipped variants. When you need a part that installs correctly the first time, the 5100012594 is the verified replacement for your machine.
Key Features
- Genuine OEM Construction: — Manufactured to the same dimensional tolerances and material grade as the original flange, ensuring a proper mating surface and load transfer at every connection point.
- Drop-In Replacement: — Matches the original bolt pattern, bore diameter, and seating geometry of the factory flange for a straightforward swap with standard tooling.
- Broad RD Series Compatibility: — Confirmed fitment across RD40-130 and RD45-140 tandem rollers in standard, offset, combination, and DPF configurations — covering a wide range of machine generations and regional variants.
- Maintains Drive and Rotation Integrity: — A correctly seated flange keeps rotating assemblies properly aligned and transmits torque without slippage or vibration; a worn or cracked flange can introduce runout, noise, and accelerated wear on adjacent components.
- Verified Part Number: — Part number 5100012594 is cross-referenced across all listed RD40-130 and RD45-140 machine configurations, so you can order with confidence that this is the correct part for your roller.
A flange is a precision-machined connection component that joins rotating or structural assemblies — securing them in alignment and transmitting force between mating parts. On tandem rollers like the RD40-130 and RD45-140, flanges are critical to maintaining the mechanical integrity of drum drive and shaft connections. When a flange wears, cracks, or becomes distorted, it can cause misalignment, vibration, or loss of drive — leading to uneven compaction results and potential damage to connected components. Replacing a failed or degraded flange promptly restores proper mechanical connection and keeps the roller operating as intended.
