Multiquip 518351440 Drum Shaft (L) - OEM Replacement Part

The left drum shaft is a critical rotating component that transmits power and supports the vibratory drum assembly in walk-behind vibratory rollers. This shaft endures continuous rotational stress, vibration loads, and the weight of the drum during compaction operations. When drum rotation becomes irregular, bearings show excessive wear, or vibration performance degrades, a worn or damaged drum shaft is often the root cause requiring replacement to restore proper roller function.

Designed specifically for the MRH601DS vibratory roller, this shaft works within a machine that generates 2,428 lbf of centrifugal force at 3,300 vpm (55 Hz) through a 13.98-inch diameter drum. The shaft must maintain alignment and integrity while supporting the 25.59-inch wide drum across a 20.47-inch distance between axes. According to Multiquip service procedures, drum shaft inspection should occur during troubleshooting of poor drum rotation or when addressing vibration issues. Replacement requires frame and drum bracket disassembly, removal of hydraulic motor connections, and lifting the unit to separate the drum assembly from the frame.
