Multiquip 513418 Exciter Shaft AR-13H - OEM Replacement Part

The exciter shaft is a critical component in the vibration system of ride-on rollers, transmitting rotational force from the hydraulic motor to the eccentric weights that generate the centrifugal compaction force. In AR-13 series rollers, this shaft operates within the drum assembly to produce up to 3,100 lbs of centrifugal force at 2,400-2,700 rpm, essential for effective asphalt and granular soil compaction. Failure symptoms include loss of vibration amplitude, unusual noise from the drum, or complete vibration failure during operation.

This genuine Multiquip exciter shaft is engineered to withstand the continuous rotational stress and vibration cycles inherent in compaction work. The shaft works in conjunction with the hydraulic manifold system that controls flow to the vibration motors, ensuring proper force generation across the 35.7-inch drum width. Regular inspection of the exciter shaft and associated bearings is critical for maintaining optimal compaction performance and preventing costly downtime on asphalt paving and site preparation jobs.
