Undercarriage failure is one of the most expensive problems in excavator operation. But here’s the truth—most of it is preventable. Regular maintenance not only extends the life of your excavator but also saves you money on costly repairs. Fulian Machinery has supported clients worldwide with premium undercarriage parts and professional support. Here’s your no-nonsense guide to keeping your excavator undercarriage in top shape.
1. Inspect Daily—No Exceptions
Check the undercarriage before every shift. Look for loose bolts, worn-out parts, oil leaks, and excessive dirt buildup. Early detection helps prevent big problems later.
- Check track tension
- Look for cracked shoes or damaged rollers
- Scan for uneven wear
2. Keep It Clean
Dirt is your enemy. Letting mud, clay, or gravel build up puts pressure on components and speeds up wear.
- Clean with a pressure washer
- Focus on sprockets, rollers, and idlers
- Make it part of your end-of-day routine
3. Adjust Track Tension Regularly
Too tight? It strains components. Too loose? It risks derailment.
- Follow manufacturer guidelines
- Measure sag between the carrier roller and idler
- Adjust using the grease cylinder system
4. Rotate the Tracks
Undercarriage components wear unevenly. Track rotation balances wear across the system.
- Especially important for machines working on slopes or turning frequently
- Swap left and right track chains if possible
5. Use the Right Parts
Generic or low-quality parts reduce your machine’s performance. Fulian’s undercarriage parts are built to OEM specs with advanced materials and heat treatment.
- Precision-forged steel
- Reinforced flanges and bushings
- Factory-tested for durability
6. Operate Smart
Your operator makes a difference. Gentle turns, balanced loads, and proper speeds protect your machine.
- Avoid sharp turns on hard surfaces
- Minimize reverse travel
- Use wide turns in confined spaces
7. Replace Worn Parts Promptly
Worn-out parts affect everything else. Delays lead to higher costs.
- Replace rollers, sprockets, and chains when wear exceeds limits
- Don’t wait for full failure
- Fulian stocks all essential undercarriage parts for fast shipping
