Multiquip 1217555 Unbalanced Mass (SM) - OEM Replacement Part

The unbalanced mass is a critical vibration component in trench roller drums that creates the eccentric force needed for soil compaction. This small (SM) size unbalanced mass generates the controlled oscillation that allows the roller drum to effectively compact trench backfill and other confined area applications. When this component wears or fails, operators will notice reduced compaction effectiveness, uneven vibration patterns, or complete loss of vibration amplitude control.

This genuine Multiquip unbalanced mass is engineered to precise weight and balance specifications to ensure proper drum vibration frequency and amplitude. Factory-tested for durability under continuous operation, this OEM component maintains the performance characteristics required for professional compaction work. Regular inspection of vibration components during scheduled maintenance helps prevent unexpected downtime and ensures consistent compaction results.

Compatible with the following Multiquip models:

• RX1575 Rammax Trench Roller
