90M130 motor

The 90M130 motor is an axial piston hydraulic motor, most likely manufactured by Sauer Danfoss based on the naming convention (90 series). It's designed to convert the high pressure of hydraulic fluid into rotary motion for various applications in mobile and industrial machinery. Here's a comprehensive look at the 90M130 motor

General Information

Displacement Likely 130 ccrev (cubic centimeters per revolution), indicating the volume of hydraulic fluid displaced per revolution of the output shaft. You can confirm this by checking the motor itself or referring to a technical manual.

Applications The 90M130 motor finds use in various applications requiring moderate to high hydraulic power for driving wheels (like forestry equipment), mixers (in concrete mixers), mowers, conveyors, or other rotating equipment.

Maintenance

Routine Maintenance

Cleanliness Maintain a clean environment around the motor to prevent dust and debris from contaminating the hydraulic system.

Oil Changes and Filter Replacement Refer to your equipment's manual or contact Sauer Danfoss for recommended intervals and oil specifications for the 90M130 motor. Clean oil is crucial to prevent wear and tear on internal components.

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.

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

Advanced Maintenance (performed by qualified technicians)

Performance Testing Testing the motor's speed, torque output, and overall performance can identify potential problems early on. A qualified technician can perform these tests to diagnose any issues.

Wear Parts Replacement Over time, components like bearings, seals, valve plates, or pistons might wear and require replacement by a qualified technician. This involves disassembling the motor, inspecting parts, and reassembling it using specialized tools and following proper procedures.
