The Wacker Neuson is a genuine OEM Rear Frame Part designed for the RD18-80, RD18-100, and RD18-100 C series tandem rollers. Sourced directly through Wacker Neuson's authorized parts program, this component meets the exact specifications of the original part it replaces. It is confirmed to fit across multiple build variants of the RD18 series, including US and SE configurations as well as the updated.3 generation models.
Key Features
- OEM Structural Integrity — Manufactured to the same dimensional and load-bearing tolerances as the original frame component, ensuring the rear section of the roller maintains its correct geometry under continuous compaction stress.
- Direct Bolt-On Replacement — Matches all original mounting points and connection interfaces on the RD18 platform, so installation aligns with the existing frame assembly without fitment adjustments.
- Broad RD18 Series Coverage — Compatible with RD18-80, RD18-100, and RD18-100 C variants across standard, US, SE, and .3 generation configurations.
- Structural Continuity — A sound rear frame keeps the drum drive, compaction system, and operator platform in correct alignment; a cracked or deformed frame part can introduce vibration misalignment and accelerate wear on surrounding components.
- Genuine Wacker Neuson Part — Carries part number 5100012678 and is backed by Wacker Neuson's OEM parts program, giving you confidence that the replacement matches the original specification.
The rear frame part is a primary structural component of the tandem roller's chassis, forming the backbone of the machine's rear section and tying together the drum assembly, drive system, and operator controls. It bears significant dynamic loads during compaction passes, absorbing vibration and maintaining the alignment of critical drivetrain and steering components. When a rear frame part becomes cracked, bent, or otherwise compromised, the entire rear assembly can shift out of alignment — leading to uneven drum contact, accelerated component wear, and potential safety concerns during operation.
