330.03.0022 Compatible Steering Pump for Volvo and Mack

What does a steering pump do?

This steering pump is engineered to provide essential hydraulic assistance within the steering system of heavy commercial vehicles. By generating high-pressure fluid, it ensures precise and effortless steering control under demanding load conditions. The unit is constructed with high-strength components to withstand the intense operational pressures required by modern heavy-duty engines.

Vehicle compatibility and engine fitment

This component is compatible with various heavy commercial vehicle models, including Volvo FH series (FH12, FH13, FH16), FM series (FM10, FM11, FM12, FM13), VHD, VNL, and B-series trucks. It also serves Renault Trucks models like Kerax, Magnum, and Premium, as well as Mack Granite and Pinnacle engines. These units are engineered to meet the requirements of Volvo D-series engines and Renault DXi series engines.

Installation and maintenance guidance

To ensure correct installation, technicians should verify the port sizes of M26x1.5 and M16x1.5 and confirm the clockwise rotation requirement. Proper maintenance of the hydraulic fluid level is critical to preventing premature wear of the internal seals and shaft bearings. Always check for leaks around the mounting flange during routine inspections.

Troubleshooting and selection

When replacing this part, it is vital to match the technical specifications of your existing unit to prevent system mismatching or pressure drops within the steering circuit.
