Wacker Neuson 5000111112 Extension Shaft

The Wacker Neuson Extension Shaft is a genuine OEM component designed for the RD11A, RD11V, and RD11AEC hydrostatic double drum vibratory rollers. As a direct OEM replacement, this shaft is manufactured to the exact specifications required by Wacker Neuson, ensuring a correct, consistent fit within the drivetrain assembly. Sourced directly through Wacker Neuson's parts program, the carries the same engineering standards as the original part installed at the factory. If your roller is showing signs of shaft wear, vibration imbalance, or drivetrain irregularities, replacing with this genuine OEM part restores full operational integrity.

Key Features

• Genuine OEM Dimensional Accuracy — Machined to exact length and diameter tolerances, ensuring correct torque transmission and shaft alignment within the drum drive assembly.
• Direct Drivetrain Replacement — Engineered to connect and seat exactly as the original, with no rework needed at mounting points or coupling interfaces.
• Confirmed Fitment for RD11 Series Rollers — Compatible with RD11A, RD11V, and RD11AEC hydrostatic double drum vibratory rollers.
• Restored Drum Drive Performance — A worn or damaged extension shaft can cause vibration loss, uneven compaction, or drivetrain noise; this replacement brings drum operation back to spec.
• Wacker Neuson Authorized Part — Carries part number 5000111112 as issued by Wacker Neuson, eliminating guesswork when cross-referencing your machine's parts list.

The extension shaft serves as a mechanical link within the drum drive system of a vibratory roller, transmitting rotational force from the drive source to the drum assembly. It extends the driveline to bridge the distance between coupled components, maintaining alignment and consistent power delivery under the high-vibration conditions these machines operate in. When an extension shaft wears, bends, or fails, the result is typically irregular drum rotation, increased vibration noise, or a complete loss of drive to the drum — all of which directly compromise compaction quality and machine reliability.
