Wacker Neuson 5000161509 Anti Tamper Cap

The Wacker Neuson is a genuine OEM Anti Tamper Cap designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers. As a direct factory replacement, this cap ensures the protected adjustment point remains sealed and compliant with emissions and operational regulations as originally configured. Wacker Neuson genuine OEM parts are manufactured to the same specifications as the components installed at the factory, so you can be confident in fit and function. Compatible across multiple RD27 configurations including standard and traction control variants, part number is the correct replacement when the original cap is lost, damaged, or removed during service.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact material and dimensional spec, ensuring the tamper-protected port remains properly sealed against unauthorized or unintended adjustment.
• Direct Drop-In Replacement — Engineered to seat directly onto the original fitting without rework, matching the thread profile or press-fit geometry of the factory-installed cap.
• Broad RD27 Series Coverage — Confirmed fitment across RD27-100 and RD27-120 hydrostatic vibratory roller variants, including both standard and traction control configurations.
• Protects Calibrated Settings — Keeps critical adjustment points sealed after service, preventing accidental or unauthorized changes that could affect roller output or compaction consistency.
• Regulatory and Emissions Compliance — Replacing a missing or damaged anti tamper cap restores the machine to its factory-sealed condition, supporting compliance with emissions control requirements on regulated equipment.

An anti tamper cap is a protective cover placed over an adjustment screw, port, or fitting that governs a calibrated system — typically related to fuel delivery, engine speed, or emissions control. Its purpose is to prevent unauthorized or accidental changes to settings that were precisely configured during manufacture or service. When this cap is missing or damaged, the underlying adjustment point is left exposed, creating a risk of unintended changes that can affect engine performance, fuel consumption, or emissions compliance. Replacing it with the correct OEM part restores the machine to its intended sealed condition.
