The 90R180 hydraulic pump manufactured by Sauer Danfoss, is an axial piston pump commonly used in various mobile and industrial applications. Here's a breakdown of maintenance, troubleshooting, and potential resources to help you with your 90R180.

Maintenance

Routine Maintenance

Oil Changes and Filter Replacement Refer to your equipment's manual or contact Sauer Danfoss for recommended intervals and oil specifications for the 90R180. This is crucial to prevent contamination and maintain optimal performance.

Fluid Level Checks Regularly check the hydraulic fluid level according to the markings on the reservoir. Low fluid levels can lead to cavitation, reduced performance, and increased wear on components.

External Inspection Look for leaks, loose connections, or visible damage on the pump housing and surrounding components. Address any issues promptly to prevent further problems.

Advanced Maintenance (performed by qualified technicians)

Cleaning Periodic cleaning of the pump's reservoir by a qualified technician can remove contaminants that contribute to wear.

Performance Testing Testing the pump's flow rate, pressure output, and overall performance can identify potential issues before they become major problems.

Wear Parts Replacement Over time, components like bearings, seals, valve plates, or drive components might wear out and require replacement by a qualified technician. This involves pump disassembly, inspection, and reassembly using the right tools and procedures.
