The Wacker Neuson 5100011964 is a genuine OEM Connection Flange designed for the RD18 series tandem rollers, including the RD18-80, RD18-100, and RD18-100 C variants. As a factory-original component, it is manufactured to the same specifications as the part it replaces, ensuring correct fitment across the full RD18 family. This flange is the right call when you need a dependable, like-for-like replacement that installs without guesswork. Confirm your model number before ordering — this part covers a wide range of RD18 configurations including US, SE, and C-suffix models.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original dimensional and material tolerances, so the flange seats and seals exactly as intended for the RD18 drivetrain or hydraulic circuit.
- Direct Bolt-On Replacement: — Matches the original mounting pattern and port geometry, allowing straightforward installation without machining or adapter hardware.
- Broad RD18 Family Coverage: — Fits RD18-80, RD18-100, RD18-100 C, and their US, SE, and .3-suffix variants, making this a single correct part across a wide production range of Wacker Neuson tandem rollers.
- Maintains Drivetrain or Hydraulic Integrity: — A properly seated connection flange keeps fluid or mechanical loads transferred cleanly between mating components; a worn or cracked flange can cause leaks, vibration, or loss of drive function.
- Verified OEM Part Number: — Part number 5100011964 is the authorised Wacker Neuson reference for this component across the RD18 series, giving you confidence you are ordering the correct part the first time.
A connection flange is a precision-machined fitting that joins two sections of a hydraulic, mechanical, or drive circuit — providing a secure, leak-free interface between mating components. On a tandem roller like the RD18 series, these flanges are critical for maintaining the integrity of the hydraulic system that powers drum vibration and propulsion. When a connection flange cracks, corrodes, or loses its sealing surface, the result can range from hydraulic fluid loss to reduced compaction force or complete loss of drum drive — all of which will halt productive asphalt or soil compaction work.
