how to put track back on mini excavator

3 min read 06-02-2025

Replacing a mini excavator track can seem daunting, but with the right tools and steps, it's a manageable task. This guide provides a comprehensive walkthrough for the process. Remember safety first! Always use appropriate safety gear and consult your excavator's manual for specific instructions.

Assessing the Damage and Gathering Supplies

Before starting, determine the extent of the damage. Is it a simple track tension adjustment or a full track replacement? A broken track requires more extensive repair.

Tools and Materials You'll Need:

New track: Ensure you have the correct size and type for your mini excavator model.
Jack stands or ramps: To safely lift the excavator. Never work under a machine supported only by its own mechanisms.
Wheel chocks: For added safety and stability.
Track tensioner wrench: This is specific to your excavator model.
Gloves and safety glasses: Essential safety equipment.
Hydraulic jack (optional): Helpful for larger excavators or difficult track removal.
Hammer and punches (optional): May be needed to free stubborn track pins.
Grease: To lubricate track pins and bushings during reassembly.

Steps to Replace a Mini Excavator Track

1. Secure the Excavator

Begin by parking the mini excavator on a level surface. Secure the machine using wheel chocks on the wheels that remain on the ground. Engage the parking brake firmly.

2. Accessing the Track

Most mini excavators require you to remove some panels or guards to access the track system fully. Consult your operator's manual to locate the appropriate access points.

3. Releasing Track Tension

Locate the track tensioner mechanism (this varies by model). Use the appropriate wrench to release the tension on the track. This is crucial; a tight track makes removal extremely difficult.

4. Removing the Old Track

Once the tension is released, the track should be easier to maneuver. Begin by disconnecting the track from the drive sprocket. This usually involves removing connecting pins or links. Work carefully and methodically. If the track is severely damaged, it may require more force. You might need a hammer and punches to help dislodge any stubborn pins.

5. Installing the New Track

Carefully align the new track with the drive sprocket and the front idler. Work methodically; it's often easier to fit the track onto the drive sprocket first, then the front idler. You'll need to connect the end links, making sure they're securely in place.

6. Adjusting Track Tension

Once the track is installed, use the track tensioner wrench to adjust the tension. Refer to your operator's manual for the correct tension specifications. Improper tension can damage the track and other components.

7. Final Checks

After tensioning, visually check the entire track for proper alignment and seating. Inspect for any loose pins or connections.

7. Reassemble the Panels/Guards

Replace any panels or guards that you removed for access.

8. Test Run

Start the mini excavator and carefully operate it for a short period, observing the track's movement. Listen for any unusual noises. If everything seems normal, you've successfully replaced the track.

Frequently Asked Questions (FAQs)

Q: How often should I inspect my mini excavator tracks?

A: Regular inspection, at least monthly or before each major job, is recommended. Check for wear, damage, or loose components.

Q: Can I replace a mini excavator track myself?

A: Yes, with the right tools and knowledge, many people can replace their mini excavator tracks themselves. However, if you're not mechanically inclined, it's best to seek professional help.

Q: What should I do if I damage my track during the replacement process?

A: Be careful not to force anything. If the track is damaged, start again with a new track. Do not try to repair the track in place.

Q: Where can I buy replacement tracks?

A: Replacement tracks can be purchased from your local equipment dealer, online retailers specializing in heavy equipment parts, or directly from the manufacturer. Make absolutely sure you order the correct size and type for your mini excavator model.
