The Wacker Neuson Cylinder is a genuine OEM component designed for the RD24, RD27, RD28, RD40, and RD45 series tandem rollers, including standard, canopy, open-ROPS, and DPF-equipped variants. As a direct OEM replacement sourced from Wacker Neuson, this cylinder is manufactured to the same specifications as the original part, ensuring a proper fit and correct function within the machine's hydraulic or engine system. This part covers an extensive range of RD series configurations — including.3-generation and electric-variant models such as the RD24e-100 and RD28e-120 — making it one of the most broadly compatible cylinders in the RD tandem roller lineup. Verify your model number and serial number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to original design tolerances, ensuring the cylinder seats, seals, and operates exactly as the factory-installed unit.
- Direct Drop-In Replacement — Engineered to match the original mounting points and port connections on RD series tandem rollers, allowing straightforward installation without custom fitting.
- Broad RD Series Compatibility — Fits RD24, RD27, RD28, RD40, and RD45 tandem rollers across standard, canopy (c), open-ROPS (o), DPF, .3-generation, and electric (e) configurations.
- Maintains Compaction Performance — A correctly functioning cylinder sustains the pressure and stroke consistency that tandem rollers depend on for uniform, effective compaction on paving and grading applications.
- Verified Part Number — Part number 5100012400 is confirmed against Wacker Neuson's OEM parts documentation, giving you confidence that you're ordering the right component for your machine.
The cylinder in a tandem roller plays a critical role in the machine's hydraulic system, converting hydraulic pressure into the linear or rotational force needed to drive key machine functions — including drum propulsion and vibration systems depending on the application. When a cylinder wears, develops internal leakage, or fails outright, the machine loses the hydraulic force it depends on, resulting in sluggish response, loss of vibration output, or a complete inability to propel or compact. Replacing a failed or worn cylinder promptly with a genuine OEM unit restores full system pressure and keeps the roller operating at its rated compaction capacity.
