Multiquip 1217091 Hub - OEM Replacement Part for Trench Rollers

The hub is a critical rotating component in the travel and drive system of trench rollers, transmitting power from the hydraulic motor to the drum assembly. This OEM hub ensures proper engagement and load distribution during compaction operations, maintaining the structural integrity required for heavy-duty vibratory roller applications.

Designed specifically for Multiquip Rammax trench rollers, this hub operates within systems that feature hydrostatic operating brakes, mechanical multiple-disc parking and emergency brakes, and travel pumps with precise torque specifications. The RX1575 travel system utilizes gear pumps with 9-tooth configurations and requires proper torque application during assembly—related components in the travel system are tightened to specifications including 10 Nm for travel assemblies and 48 Nm for pinion installations. The hub works in conjunction with the hydraulic travel system that includes forward/reverse travel valves and vibration control components.

This hub is engineered to withstand the demanding conditions of trench compaction work, where precise hydraulic pressure control (steering pressure of 67 ± 8 bar) and reliable mechanical power transfer are essential for equipment performance.
