The Multiquip 513428 Exciter Shaft AR-13H is a genuine OEM component designed for the AR13H ride-on asphalt tandem drum roller. Sourced directly from Multiquip, this shaft is built to the exact specifications required for correct vibratory system operation on the AR13H. If your roller is experiencing reduced compaction output or abnormal drum vibration, a worn or failed exciter shaft is a common cause — and replacing it with the correct OEM part ensures the vibratory system is restored to its intended performance. DHS Equipment stocks the 513428 so you can get your AR13H back in service without compromise.
Key Features
- OEM-Matched Shaft Geometry — Manufactured to the precise dimensions and tolerances required by the AR13H vibratory drum system, ensuring correct rotational balance and eccentric mass alignment.
- Direct-Fit Replacement — Engineered to install in the existing exciter housing of the AR13H with no reworking of mounting points or bearing seats.
- AR13H Roller Compatibility — Confirmed fitment for the Multiquip AR13H ride-on asphalt tandem drum roller.
- Restores Full Compaction Force — A correctly functioning exciter shaft delivers consistent eccentric vibration to the drum, maintaining the compaction energy output the AR13H is rated to produce.
- Genuine Multiquip OEM Quality — Produced to Multiquip's material and hardness standards for rotating drivetrain components, supporting the service life expected from the vibratory assembly.
The exciter shaft is the rotating component at the heart of a vibratory roller's compaction system. Housed within the drum, it carries an eccentric weight that — when spun at operating speed — generates the centrifugal force transmitted to the drum and into the ground below. This vibration dramatically increases compaction depth and density compared to static rolling alone. When the exciter shaft wears, cracks, or fails, vibration output drops or stops entirely, leaving the machine unable to achieve target compaction density and forcing costly rework of the finished surface.
