The Multiquip 451315010 Eccentric Rotor R400G/D is a genuine OEM component designed for the R-400G walk-behind vibratory roller. Sourced directly from Multiquip, this rotor is an exact-match replacement that restores proper vibration output to your roller without adaptation or guesswork. If your R-400G is producing weak compaction or irregular vibration, a worn or damaged eccentric rotor is a common cause — and 451315010 is the correct OEM part to bring it back to spec.
Key Features
- OEM-Grade Mass Balance — Manufactured to the original eccentric weight and dimensional tolerances, ensuring consistent vibration amplitude across the drum.
- Direct-Fit for R-400G Rollers — Engineered specifically for the R-400G roller platform, this rotor installs into the existing drum assembly without modification.
- Restored Compaction Performance — A correctly balanced eccentric rotor delivers the centrifugal force needed for uniform soil and asphalt compaction on every pass.
- Genuine Multiquip OEM Part — Backed by Multiquip as an authentic replacement, so you know you're getting the correct specification for your machine.
- Durable Construction — Built to withstand the continuous high-speed rotation and mechanical stress inherent to vibratory roller operation in demanding site conditions.
The eccentric rotor is the heart of a vibratory roller's compaction system. Mounted inside the drum, it spins at high speed to generate centrifugal force, which translates into the vibration that drives compaction energy into the ground. When the rotor is worn, damaged, or out of balance, vibration output drops or becomes uneven — leading to poor compaction density, inconsistent surface finish, and increased pass counts. Replacing a failed rotor with the correct OEM part restores the drum's designed vibration frequency and amplitude, putting your R-400G back to full compaction capacity.
