The Auxiliary Pump on a double drum vibratory roller supplies hydraulic flow to secondary circuits — typically supporting functions such as steering, drum drive, or vibration activation depending on the machine's hydraulic layout. Without adequate flow from this pump, the roller may lose responsiveness in one or more operating systems, reducing compaction effectiveness or making the machine unsafe to operate on grade. Replacing a failing Auxiliary Pump promptly restores full hydraulic capacity and keeps the machine performing as intended across all drum and drive functions.
