The Wacker Neuson 5100012265 is a genuine OEM Connection Flange designed for the RD40-130 and RD45-140 tandem roller series and the RC110 single-drum soil compactor series. Sourced directly from Wacker Neuson, this part meets the exact dimensional and material standards of the original component. Fitment covers a wide range of RD40-130 and RD45-140 configurations — including open ROPS, cab, DPF, and combination variants — as well as RC110 ROPS and CAB machines. When you order part number 5100012265, you are getting the same component that left the factory with your machine.
Key Features
- Genuine OEM Material Integrity — Manufactured to Wacker Neuson's original metallurgical spec, ensuring the flange maintains correct sealing surface geometry and torque-load capacity under compaction duty cycles.
- Drop-In Installation — Matches original bolt pattern and mating face dimensions exactly, so the flange seats and seals without rework or shimming.
- Broad Fitment Across Two Machine Families — Confirmed for RD40-130 and RD45-140 tandem rollers (open, cab, DPF, and combination variants) and RC110p and RC110 single-drum soil compactors in both ROPS and CAB configurations.
- Preserves Drivetrain Alignment — A correctly fitted connection flange keeps rotating or hydraulic assemblies in true alignment; a worn or cracked flange can introduce vibration, fluid loss, or accelerated wear to adjacent components.
- Verified Part Number — Order with confidence knowing 5100012265 is the exact OEM reference for these RD and RC series machines, eliminating guesswork when cross-referencing service documentation.
A connection flange serves as the structural and sealing interface between two mating assemblies — typically linking a driveshaft, hydraulic circuit, or rotating component to its counterpart housing or coupling. On heavy compaction equipment like the RD40-130, RD45-140, and RC110 series, this joint is subjected to sustained vibration, high torque, and variable load, making dimensional accuracy and material strength critical. If the flange develops cracks, distortion, or surface damage, the connection it maintains can leak, slip, or fail entirely, taking neighboring components with it.
