Wacker Neuson 5100011875 Steering Cylinder

The Wacker Neuson Steering Cylinder is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, O, DPF, and US variants. As a direct factory replacement, this part meets the exact specifications set during original production, ensuring correct hydraulic operation and steering response across all covered configurations. Whether you're servicing an RD40-130 DPF, an RD45-140 C, or any other model in the RD40/RD45 family, part number is the correct OEM replacement for your machine. Order with confidence knowing this cylinder fits the full range of RD40-130 and RD45-140 series machines.

Key Features

• OEM Hydraulic Tolerancing — Manufactured to Wacker Neuson's original bore and seal specifications, ensuring correct pressure response and consistent articulation force throughout the cylinder's stroke.
• Direct-Mount Replacement — Matches the original mounting points and hydraulic port configuration, allowing straightforward installation without machining or adaptation.
• Broad RD40/RD45 Series Coverage — Fits the full RD40-130 and RD45-140 model family, including standard, C, O, US, .3, and DPF variants, across multiple production series.
• Maintains Precise Steering Articulation — A correctly functioning steering cylinder keeps the roller tracking true and delivering consistent compaction passes; a worn or leaking cylinder causes unpredictable steering and uneven drum pressure.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5100011875 carries the full backing of the manufacturer's quality standards for hydraulic components.

The steering cylinder is the hydraulic actuator responsible for articulating the front and rear drum sections of a tandem roller relative to each other, allowing the operator to steer and maneuver the machine across the compaction surface. It works by converting hydraulic pressure from the machine's steering circuit into controlled linear movement, pivoting the frame to change direction. When the cylinder develops internal leaks, seal failure, or physical damage, steering becomes sluggish, imprecise, or unresponsive — compromising both operator control and the quality of the compacted surface.
