Wacker Neuson 5100013319 Wiper Arm for RD40-130 & RD45-140 Tandem Rollers

The Wacker Neuson Wiper Arm is a genuine OEM Wiper Arm designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, O, US, DPF, and.3 variants. As a direct OEM replacement sourced from Wacker Neuson, part is built to the same specifications as the original component it replaces. This Wiper Arm covers an extensive range of RD-series configurations, making it the correct choice whether you're running a closed-cab, open-cab, or DPF-equipped machine. Verify your model number against the fitment list to confirm compatibility before ordering.

Key Features

• Genuine OEM Sweep Geometry — Manufactured to the original arc and pivot dimensions, ensuring the wiper blade follows the correct sweep path across the drum cab glass without skipping or streaking.
• Direct Bolt-On Replacement — Matches the original mounting interface and pivot attachment point on RD40-130 and RD45-140 series machines, so installation is straightforward with standard hand tools.
• Broad RD-Series Coverage — Compatible with RD40-130 and RD45-140 variants including standard, C, O, US, .3, and DPF configurations — a single part number covering the full production range of these tandem rollers.
• Clear Visibility in Wet Conditions — A properly functioning wiper arm holds the blade firmly against the glass under operating vibration; a worn or bent arm lifts away from the surface and leaves the operator with reduced forward visibility in rain or wash-down conditions.
• Operator Visibility & Safety Relevance — On a compaction roller working close to edges, drop-offs, and ground crew, unobstructed cab visibility is a genuine safety consideration — a failed wiper arm directly compromises the operator's line of sight.

The wiper arm is the rigid linkage that connects the wiper motor's pivot shaft to the wiper blade, holding the blade under spring tension against the cab glass as it sweeps back and forth. On a tandem roller operating in wet weather or during site wash-down, the arm must maintain consistent blade pressure despite constant machine vibration; if the arm becomes bent, fatigued, or detaches from the pivot, the blade lifts off the glass and wiper function is lost entirely. Replacing a damaged or worn wiper arm promptly restores full operator visibility and keeps the cab glass clear under all working conditions.
