Multiquip 506188 Motor Hydraulic VR36H - OEM Replacement Part

The hydraulic motor powers the vibration system in ride-on rollers, delivering the centrifugal force necessary for soil compaction operations. When this motor fails, symptoms include no vibration output, low vibration performance, or complete loss of compaction capability—directly impacting your project timeline and efficiency.

This VR36H hydraulic motor receives high-pressure oil from the pump through the valve block manifold and is controlled by an electric control valve operated via the pushbutton switch on the travel lever. In the AR13H series, this motor generates 3,100 lbs (1,406 kg) of centrifugal force at 4000 vibrations per minute when operating properly. The hydraulic system directs oil to either the steering valve or the vibration motor depending on switch position.

Common failure indicators include broken motor couplers, low hydraulic pressure affecting vibration output, or binding vibrator shafts. Troubleshooting procedures recommend removing the motor from the drum to determine if binding results from the shaft or motor itself. The system requires ISO 46 type hydraulic oil and regular maintenance of the hydraulic oil filter every 500 hours or 3 months.
