Multiquip 802928 Hydraulic Gear Pump Hose - OEM Replacement Part

This hydraulic hose connects the gear pump to the manifold control valve block in the AR14H vibratory roller's hydraulic system, supplying pressurized oil to power both the drum vibratory system and the articulating steering system. The gear pump, which is connected to the axial hydraulic pump, distributes oil through this hose to the control valve block before flowing to the hydraulic motor that rotates the eccentric weights inside the sealed drum housing.

In the AR14H hydraulic system, the gear pump operates independently from the hydrostatic travel system, providing dedicated hydraulic power for vibration and steering functions. This hose must maintain pressure integrity to ensure proper oil flow from the gear pump through the manifold to the vibratory motor. Hydraulic hose failure can result in loss of vibration capability or steering function, making this a critical component for roller operation. When replacing, inspect all hydraulic connections and verify system uses ISO 46 type hydraulic oil per manufacturer specifications.
