Slew Motors for Excavators and Vikfin's Commitment to Excellence

Excavators, the workhorses of construction sites, owe much of their agility and versatility to a critical component known as the slew motor. This unsung hero is responsible for the excavator's ability to rotate its upper structure, allowing operators to maneuver with precision and tackle diverse tasks. In this blog, we will delve into the intricate world of slew motors, exploring their major components, functions, maintenance tips, signs of failure, and the invaluable solutions offered by Vikfin, a renowned provider of refurbished OEM slew motors in South Africa.

Understanding Slew Motors:

1. Major Components:

• Motor: The heart of the slew system, providing the necessary power for rotation.

• Gearbox: Responsible for transmitting power from the motor to the slew ring.

• Slew Ring: A large bearing that facilitates smooth rotation.

• Brakes: Ensure controlled stopping of the slew movement.

1. Functions of Slew Motors:

• Precision Rotation: Enables operators to position the excavator with accuracy.

• Versatility: Allows for efficient work in confined spaces or complex job sites.

• Productivity Boost: Enhances overall excavator performance and efficiency.

Maintenance Tips for Slew Motors:

1. Regular Inspections:

• Check for leaks, unusual noises, or vibrations during operation.

• Inspect hydraulic connections for any signs of damage or wear.

1. Greasing and Lubrication:

• Ensure proper lubrication of slew bearings to prevent friction and wear.

• Follow the manufacturer's guidelines for the type and frequency of greasing.

1. Temperature Monitoring:

• Keep an eye on the motor's temperature to identify potential overheating issues.

• Overheating can lead to premature wear and reduced motor efficiency.

Signs of Slew Motor Failure:

1. Unusual Noises:

• Grinding, squealing, or clunking sounds may indicate internal issues.

1. Reduced Rotation Speed:

• Sluggish or uneven rotation could signify motor or gearbox problems.

1. Hydraulic Leaks:

• Fluid leaks around the slew motor may suggest damaged seals or connections.

Step-by-step guide on how to change an excavator slew motor

Changing an excavator slew motor is a complex task that requires mechanical expertise and adherence to safety protocols. It's essential to follow manufacturer guidelines and use proper safety equipment throughout the process. Here is a detailed step-by-step guide on how to change an excavator slew motor:

Materials and Tools:

1. Replacement slew motor

2. Crane or lifting equipment

3. Hydraulic hoses and fittings

4. Wrenches, sockets, and other basic hand tools

5. Hydraulic fluid and disposal containers

6. Jack stands

7. Safety gear (gloves, safety glasses, hard hat, steel-toed boots)

Step 1: Safety First Before starting any work, ensure the excavator is on stable ground and use appropriate safety gear. Engage the parking brake, turn off the engine, and disconnect the battery to prevent accidental starts.

Step 2: Access the Slew Motor Locate the existing slew motor on the excavator. Depending on the excavator model, this may involve removing access panels, guards, or other components obstructing the motor.

Step 3: Disconnect Hydraulic Lines Use appropriate tools to disconnect the hydraulic lines connected to the slew motor. Be prepared for hydraulic fluid to drain out, so have a container ready for disposal. Cap or plug the open hydraulic lines to prevent contamination.

Step 4: Remove Slew Motor Mounting Bolts Using wrenches or sockets, remove the mounting bolts securing the slew motor to the excavator. Ensure that the excavator is properly supported on stable ground or with the use of jack stands.

Step 5: Detach Slew Motor Carefully detach the slew motor from the excavator's slew ring. In some cases, you may need lifting equipment or a crane to hoist the motor out of its position. Exercise caution to prevent damage to surrounding components.

Step 6: Install the Replacement Motor Position the new slew motor in place, aligning it with the mounting holes. Reattach and tighten the mounting bolts securely. Ensure proper alignment with the slew ring to prevent future issues.

Step 7: Reconnect Hydraulic Lines Connect the hydraulic lines to the new slew motor. Pay attention to proper fitting and tightening to prevent leaks. Remove any caps or plugs from the hydraulic lines.

Step 8: Hydraulic System Check Refill the hydraulic system with the manufacturer-recommended hydraulic fluid. Start the excavator and check for any hydraulic leaks or abnormalities in the slew movement. Bleed the hydraulic system if necessary.

Step 9: Functionality Test Test the new slew motor by rotating the upper structure of the excavator. Check for smooth and controlled movement. Listen for any unusual noises and monitor for any signs of stress or strain.

Step 10: Final Checks and Cleanup Perform a final inspection of all connections, bolts, and hydraulic lines. Ensure that safety guards or panels are properly reinstalled. Dispose of any waste materials, such as old hydraulic fluid, in an environmentally friendly manner.

Changing an excavator slew motor is a complex task that should be undertaken by experienced and trained professionals. If you are unsure of any step in the process, consult the manufacturer's manual or seek assistance from a qualified technician. Additionally, if you encounter any challenges or signs of malfunction after replacement, it's crucial to address them promptly to prevent further damage and ensure the excavator's optimal performance.
