Wacker Neuson 5000161537 Anti Tamper Cap

The Wacker Neuson Anti Tamper Cap is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. Sourced directly from Wacker Neuson, this cap ensures the protected fitting or adjustment point remains sealed and secure against unauthorized or accidental interference. It is a direct-fit replacement for both RD27-100 and RD27-120 machines, installing exactly as the original without any rework or modification to the surrounding hardware.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional specification, ensuring the cap creates the correct retention and seal on the protected port or fitting.
• Drop-In Replacement — Engineered to the same profile as the factory-installed cap, seating flush and locking into place the same way the original does.
• Confirmed Fitment — Compatible with RD27-100 and RD27-120 hydrostatic vibratory rollers, covering both model configurations in the RD27 series.
• Tamper Protection Maintained — Keeps calibrated settings, fuel system adjustments, or sealed service points protected from accidental contact or unauthorized adjustment in the field.
• Regulatory and Service Compliance — Anti tamper caps on engine and emissions-related components are often required to remain in place for compliance with equipment regulations; replacing a missing or damaged cap restores that compliance.

An anti tamper cap is a protective cover placed over a calibrated adjustment point, fuel system screw, or sealed service fitting to prevent accidental changes or unauthorized tampering. On compaction rollers like the RD27 series, these caps are commonly found on carburetor mixture screws, injection pump adjustment points, or other settings that are preset at the factory and must not be altered in the field. A missing or damaged cap leaves that adjustment point exposed, which can lead to unintended changes to machine performance, emissions output, or fuel delivery settings.
