The Wacker Neuson Lock Arm Weldment is a genuine OEM component designed for the RD27-100 and RD27-120 series tandem rollers. Sourced directly from Wacker Neuson, this part carries the same engineering standards as the original unit installed at the factory. It is compatible across multiple RD27 configurations, including Hydrostatic Vibratory Roller, Ride-On Roller, and RD27 Pro variants. When you need a direct, verified replacement for your RD27 tandem roller, part number is the correct choice.
Key Features
- Genuine OEM Weldment Construction — Manufactured to the same structural tolerances as the original, ensuring the weldment maintains its load-bearing integrity under the operational stresses of a tandem roller.
- Direct Bolt-On Replacement — Engineered to match the original mounting points and geometry on the RD27 frame, so installation aligns without rework or modification to adjacent components.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 models across Hydrostatic Vibratory Roller, Ride-On Roller, and RD27 Pro T4F configurations.
- Structural Locking Function — Maintains correct articulation lock engagement on the roller frame; a worn or damaged weldment can compromise the machine's ability to safely lock the articulation joint during transport or service.
- Verified OEM Part Number — Ordering by confirmed part number 5200009306 eliminates fitment guesswork and ensures the correct assembly reaches your machine.
The Lock Arm Weldment is a structural fabricated component that forms part of the articulation locking system on the RD27 tandem roller. Its primary role is to engage and secure the articulation joint between the front and rear frames — a critical function when the machine needs to be locked out for transport, maintenance, or safe parking on a slope. Because this component is a welded assembly rather than a cast or machined single piece, it must maintain its dimensional integrity to engage correctly with the locking mechanism. If the weldment becomes cracked, bent, or worn, the articulation lock may fail to engage fully, creating a safety hazard and potentially leaving the machine out of service until the part is replaced.
