The Wacker Neuson is a genuine OEM Lock Arm designed for the RT56-SC, RT82-SC, RTx-SC2, RTLx-SC3, and RTKx-SC3 series remote-controlled vibratory trench rollers. As a direct factory replacement, this part is manufactured to the same specifications as the original, ensuring a correct fit across a wide range of SC2 and SC3 generation trench roller configurations. Whether you are servicing an RT82-SC2, an RTL82-SC3, or an RTKx-SC3 with Compatec, part number is the authorized replacement for this position. Confirm your machine number against the fitment list before ordering to ensure compatibility with your specific unit.
Key Features
- Genuine OEM Construction: — Manufactured by Wacker Neuson to original design tolerances, ensuring the arm engages and locks with the same resistance and travel as the factory-installed component.
- Direct-Fit Replacement: — Mounts to the same attachment points as the original Lock Arm, requiring no modification to the surrounding assembly during installation.
- Broad Trench Roller Fitment: — Compatible across RT56-SC, RT82-SC, RT82-SC2, RTx-SC2, RTL82-SC3, RTLx-SC3, and RTKx-SC3 series vibratory trench rollers, including EU variants and Compatec-equipped models.
- Structural Integrity for Articulated Operation: — A correctly functioning Lock Arm maintains secure positioning of the roller's articulated frame sections; a worn or damaged arm can compromise machine control and compaction consistency in trench applications.
- Operational Safety Relevance: — On remote-controlled articulated trench rollers, the Lock Arm is a structural locking component. Using a genuine OEM replacement helps ensure the locking mechanism performs as designed under load in confined trench environments.
The Lock Arm on a Wacker Neuson remote-controlled trench roller is a structural component that secures or constrains movement within the machine's articulated frame assembly. In trench roller applications, controlled articulation is critical — the roller must track accurately in narrow, confined spaces, and any play or failure in a locking component can result in unpredictable machine movement. When the Lock Arm wears, bends, or breaks, the machine may lose the ability to hold a fixed frame position, directly affecting compaction pass accuracy and operator control via the remote system.
