Your excavator works hard every day. The undercarriage takes the brunt of rough terrain. Small issues here turn into big repairs fast. Regular checks keep you ahead of failures. At Fulian Machinery, we build premium undercarriage parts and guide you on maintenance. Let’s walk through a simple inspection you can do before every shift.
Start with a visual sweep. Walk around the machine. Look for cracks or dents in track frames. Check for loose or missing bolts. Inspect the track rollers. They sit under heavy loads. Worn rollers show flat spots. Oil leaks around seals mean bushing failure. Replace faulty rollers early to avoid chain damage.
Next, examine the idlers. These guide the track back to the sprocket. Spin each idler by hand if you can. It should turn smoothly. No grinding or wobble. Damaged idlers lead to poor track tension and misalignment. Fulian idlers use forged steel and precision seals. They resist dirt and moisture for long life.
Move to the sprockets. These drive the track chain. Look at tooth shape. Sharp, hooked teeth mean wear. Measure the gap between teeth. Compare to OEM specs. If the gap is too wide, sprockets slip under load. Cheap sprockets wear fast. Fulian sprockets are heat-treated for extra toughness. They match original equipment standards.
Check the track chain and links. Push and pull each link side to side. Excessive movement shows chain stretch. Stretched chains reduce tension and can derail. Inspect bushings and pins for wear. Replace worn chains in pairs with sprockets. This avoids mismatched wear that cuts life short.
Inspect the track shoes. Cracked, bent, or missing grousers reduce traction. Loose shoes cause track misalignment. Tight shoes strain rollers and motors. Use the right shoe type for your terrain. Fulian offers single, double, and swamp shoe options. Each designed for specific job sites.
Now look at grease points and tension adjusters. Clean fittings before greasing. Use proper grease type and volume. Over-greasing over-tightens tracks and stresses parts. Under-greasing lets tracks sag. Inspect the tension cylinder for leaks. Fulian tensioners feature sealed systems to keep debris out.
Finish with an undercarriage clean. Remove mud, rocks, and debris. Build-up traps moisture and accelerates corrosion. A clean undercarriage lets you spot issues earlier. Make cleaning part of your end-of-day routine.
