The Wacker Neuson Arm Locking Pin is a genuine OEM component designed for the RD27-100 and RD27-120 tandem roller series. As a direct OEM replacement, this pin is built to the exact tolerances required by the RD27 platform, ensuring correct engagement and secure retention in the articulating arm assembly. It fits a wide range of RD27 configurations including Pro T4F, Basic T4F, and Ride-On Roller variants. When you order by part number, you can be confident you're getting the right part for your machine.
Key Features
- OEM-Spec Pin Tolerancing — Manufactured to Wacker Neuson's exact dimensional specifications, ensuring correct fit within the arm's locking mechanism without play or binding.
- Direct Replacement for RD27 Articulating Arm — Installs directly into the arm locking point on the RD27-100 and RD27-120, matching the original pin geometry and retention profile.
- Broad RD27 Series Coverage — Compatible with RD27-100 and RD27-120 machines across Pro T4F, Basic T4F, and multiple Ride-On Roller configurations.
- Maintains Articulation Integrity — A correctly fitted locking pin keeps the articulated frame locked securely during transport and service positions, preventing unintended movement of the roller's front and rear frames.
- Operational Safety Relevance — The arm locking pin is a critical safety component; a worn, missing, or incorrectly sized pin compromises the machine's ability to safely lock the articulation joint during maintenance or transport.
The arm locking pin on a tandem roller is a structural safety component that secures the articulation joint between the front and rear frame sections of the machine. During transport or when service work is performed under or around the roller, this pin locks the articulated joint to prevent the front and rear frames from pivoting relative to each other. If the locking pin is missing, worn, or damaged, the articulation joint cannot be reliably secured, creating a serious safety hazard for anyone working near the machine and potentially allowing frame movement that damages surrounding components.
