Wacker Neuson 5100013120 Agitator Finger

The Wacker Neuson Agitator Finger is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers. Sourced directly from Wacker Neuson, this part meets the same specifications as the original, ensuring a consistent, correct installation every time. Fitment covers a broad range of configurations across both series, including standard, C, O, and.3 variants such as the RD40-130, RD40-130 C, RD40-130 O, RD40-130.3, RD45-140, RD45-140 C, RD45-140 O, and RD45-140.3. When your agitator finger shows wear or damage, replacing it with the genuine Wacker Neuson keeps compaction performance where it needs to be.

Key Features

• Genuine OEM Durability — Manufactured to Wacker Neuson's original material and dimensional standards, so the finger maintains its shape and grip through demanding compaction cycles.
• Direct Drop-In Replacement — Matches the original mounting geometry of the agitator assembly, allowing straightforward installation without modification to surrounding components.
• Broad Series Compatibility — Fits RD40-130 and RD45-140 tandem rollers across standard, C, O, and .3 configurations, covering a wide range of Wacker Neuson compaction equipment in the field.
• Consistent Compaction Output — A correctly functioning agitator finger ensures smooth, even material movement through the drum system; a worn or broken finger leads to uneven compaction and premature surface defects.
• Verified OEM Part Number — Ordering by part number 5100013120 confirms you are receiving the exact component specified for these machines, eliminating guesswork on fitment.

The agitator finger is a wear component within the drum assembly of a tandem roller, responsible for agitating and moving material as the drum rotates to promote even compaction across the surface being worked. It works in conjunction with the surrounding agitator mechanism to prevent material buildup and maintain consistent drum contact with the substrate. When an agitator finger becomes worn, cracked, or broken, compaction uniformity suffers and additional stress can be placed on adjacent drum components, making timely replacement essential to keeping the machine performing at its rated output.
