90M055 Motor

The 90M055 motor is an axial piston motor, manufactured by Sauer Danfoss based on the naming convention (90 series). It's a hydraulic motor that converts hydraulic fluid pressure into rotary motion to drive various machinery. Here's what you can expect to know about the 90M055 motor.

General Information

Displacement Likely 55 ccrev (cubic centimeters per revolution), indicating the volume of fluid displaced per revolution of the shaft. This information might be available on the motor itself or in a technical manual.

Applications The 90M055 motor can be found in various mobile and industrial applications where hydraulic power is needed for driving wheels, mixers, conveyors, or other rotating equipment.

Maintenance

Routine Maintenance

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

Oil Changes and Filter Replacement Refer to your equipment's manual or contact Sauer Danfoss for recommended intervals and oil specifications for the 90M055 motor. 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 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 issues before they become major problems. A qualified technician can perform these tests.

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 motor disassembly, inspection, and reassembly using the right tools and procedures.

Parts availability for the 90M055 motor (if applicable).

General maintenance recommendations for Sauer Danfoss hydraulic motors (which might be applicable to the 90M055).

Equipment Manuals If the 90M055 motor is part of a larger piece of equipment, consult the equipment's manual. It might include a maintenance section specific to the motor model used in your machine.

Online Resources (Use with Caution) Due to the potential lack of specific information, use online resources with caution. Look for resources from reputable sources that discuss general axial piston motor maintenance procedures. However, prioritize information from Sauer Danfoss or a qualified technician for the most accurate guidance.

Safety Considerations

Hydraulic systems operate at high pressures and can cause serious injuries if not handled improperly. Here are some safety tips

Leave complex procedures to qualified technicians.

Before performing any maintenance, ensure the system is depressurized and locked out to prevent accidental startup.

Wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and sturdy footwear.

Additional Tips

The specific model number of your 90M055 motor might have additional letters or numbers after the base model number (e.g., 90M055 NC 0 N 7 N 0 C6 W 00 NNN 00 00 20). This additional code can provide details about the motor's control type, shaft configuration, and other specifications. You can use this code to search for more specific information online or contact Sauer Danfoss for further assistance.
