Multiquip 802929 Hydraulic Axle Pump Hose - OEM Replacement Part

This hydraulic hose connects the axial hydraulic pump to the gear pump system on Multiquip vibratory rollers, enabling power delivery to both the drum vibratory system and articulating steering system. The axle pump hose is a critical component in the hydraulic circuit that supplies oil flow from the pump to the manifold control valve block.

In the AR14H hydraulic system, the gear pump connected to the axial hydraulic pump provides pressurized oil that flows through this hose to the control valve block, which then directs flow to the hydraulic motor rotating the eccentric weights inside the drum's sealed housing. The hose must maintain pressure integrity as the system operates in both forward and reverse modes, with ports A and B alternating between high-pressure and suction functions depending on travel direction.

Failure symptoms include loss of vibration power, steering malfunction, hydraulic oil leaks near the pump assembly, or reduced compaction performance. This hose should be inspected regularly for wear, cracking, or damage during routine hydraulic system maintenance.
