The Wacker Neuson Oil Pump Complete is a genuine OEM component designed for the RD7Ye and RD10Yehf series walk-behind tandem rollers. Sourced directly from Wacker Neuson, this assembly meets the same specifications as the part originally installed at the factory, ensuring a direct, hassle-free swap. Compatible across a broad range of RD7Ye configurations — including LRC and HRC variants — as well as the RD10Yehf LRC, this pump is the correct replacement for any of the listed roller models.
Key Features
- Genuine OEM Oil Circuit Integrity — Manufactured to Wacker Neuson's original tolerances, ensuring consistent oil pressure and flow output across the full operating range of the roller.
- Complete Assembly, Ready to Install — Supplied as a complete pump unit, so all internal components are matched and pre-assembled — no sourcing individual sub-parts required.
- Broad RD7Ye and RD10Yehf Compatibility — Fits multiple RD7Ye variants (LRC, HRC, and base configurations) plus the RD10Yehf LRC, covering a wide range of Wacker Neuson walk-behind tandem roller models.
- Protects Engine and Drive Components — A functioning oil pump maintains proper lubrication throughout the machine; a worn or failed pump leads to accelerated wear, overheating, and potential seizure of critical internal components.
- Verified Part Number Match — Part number 5100031888 is the correct Wacker Neuson reference for these models, giving you confidence that you are ordering the right component before it ships.
The oil pump is responsible for circulating engine or hydraulic oil under pressure to the moving components that depend on lubrication to function correctly. Without adequate oil flow, friction builds rapidly, temperatures rise, and internal components begin to wear at an accelerated rate — ultimately leading to machine failure if left unaddressed. Replacing a failing oil pump with a genuine OEM unit like the 5100031888 restores proper lubrication pressure and keeps the roller operating as intended.
