90R042 hydraulic pump Maintenance

The 90R042 hydraulic pump, manufactured by Sauer Danfoss based on the naming convention, is an axial piston pump. Here's a breakdown of maintenance practices you can follow to keep your 90R042 pump in good condition

Routine Maintenance

Oil Changes and Filter Replacement This is essential to remove contaminants and maintain optimal performance. Refer to your equipment's manual or contact Sauer Danfoss for recommended intervals and oil specifications for the 90R042 pump.

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 help 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. This should be done by a technician.

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.
