VOE11173538 Volvo Hydraulic Gear Pump for L150E L180E L220D

Product Overview

VOE11173538 (cross references 11173538, 15068638, 11411016, 15043454, 11173536, 05579296 etc.) is the genuine Volvo main hydraulic gear pump designed for Volvo wheel loaders L150E, L180E and L220D. As the core power source of the machine’s hydraulic system, it delivers stable high-pressure flow to the implement and steering circuits. Fully interchangeable with original Volvo units, it enables direct drop-in replacement without modification to mounting interfaces or piping. Every unit undergoes 100% simulated operating-condition testing to ensure reliability and service life under heavy-duty conditions.

• Main hydraulic system of Volvo L220D wheel loaders
• Related Volvo loader implement and steering hydraulic circuits
• Heavy construction equipment repair and remanufacturing requiring OEM-matched gear pumps

Expert Maintenance Tips

1. Thoroughly clean the reservoir and lines before installation; check suction and return filters to prevent contamination of the new pump.
2. Ensure correct shaft alignment and coupling installation; tighten flange bolts to the specified torque to avoid excessive radial or axial loads.
3. Fill and thoroughly bleed the system before first start-up; verify case drain and system pressure. Use hydraulic oil meeting Volvo specifications.
4. Regularly monitor outlet pressure, flow and noise; shut down immediately if abnormalities appear. Store long-term units in a dry environment and rotate the shaft periodically.
