How to spot worn excavator parts
Keeping your excavator working well starts with finding problems early. You can stop sudden breakdowns and expensive fixes by checking your machine step by step. Here’s how you look for damage and keep your excavator running.
Listen for strange sounds
Begin by listening when your excavator is working. Strange sounds can mean something is wrong. If you hear a whining hydraulic pump, it could mean low fluid or worn parts. Clanging noises might show loose track parts or worn pins and bushings. Grinding sounds often mean bearings or gears are worn. Knocking or clicking noises can come from worn plungers or cylinders. Squeaking or grinding can happen if there is not enough oil. If you hear turbulence and noise, valve plates may be broken and messing up fluid flow. These sounds are early signs of undercarriage problems and can cause failure if ignored.
Look for leaks
Leaks are a common warning sign when you check your excavator. Look for wet spots or puddles near hoses, fittings, and cylinders. Broken seals let dirt and dust in, which wears out parts faster. An open reservoir lets in dirt, causing more wear and possible breakdowns. Cylinder failures usually happen from worn parts or rust, showing bad damage. Always check for leaks every day to stop hydraulic system failure.
Type of Leak | What It Means |
|---|---|
Damaged seals | Dirt and dust get in, causing more wear |
Open reservoir | Lets in dirt, causing big problems |
Cylinder failures | Worn parts or rust, showing bad damage |
Watch for performance problems
Notice how your excavator moves and works. If it moves unevenly, rollers may be misaligned or worn. If it works slowly, sprockets or track frames may be damaged. If it has less power, tracks or idlers may be broken. Too much shaking means rollers are worn or not lined up right. Grinding or clicking noises can come from broken sprockets or track parts. If the track slips while digging or moving, sprockets may be worn, track tension may be wrong, or tracks may be misaligned. These problems are early signs of undercarriage issues and can cause failure if not fixed.
Movement Problem | Possible Cause | What To Do |
|---|---|---|
Uneven Movement | Misaligned or worn rollers | Check and replace bad rollers |
Slow Operation | Worn sprockets or broken frames | Replace sprockets, check track tension |
Less Power | Broken tracks or idlers | Inspect and replace if needed |
Vibration or Noise Problem | Possible Cause | What To Do |
|---|---|---|
Too Much Vibration | Worn or misaligned rollers | Fix or replace rollers |
Grinding or Clicking Noise | Broken sprockets or track parts | Replace sprockets, check for cracks |
Check for visible damage
Looking closely helps you find problems before they get worse. Look for cracks on the track surface, which can cause breakage and loss of grip. Uneven wear or thinning means the track will not last as long and will lose traction. Worn teeth, especially thin or chipped ones, make the track slip and lose grip. Cracks in the idler or frame can cause misalignment and frame failure. Always measure track wear to catch these problems early.
Damage Type | What To Look For | What Happens |
|---|---|---|
Cracking | Small or deep cracks on track surface | Track breaks, loses grip |
Excessive Wear | Uneven wear or thinning | Track lasts less, loses grip |
Worn Teeth | Teeth are thin or chipped | Slips, does not grip well |
Visible Cracks | Cracks in idler or frame | Misalignment, frame breaks |
Use special tools
Modern tools help you find hidden problems that you cannot see. Ultrasonic testing finds cracks and thickness changes in rollers, tracks, and sprockets. Thermal imaging shows overheating parts, like bearings and bushings, by showing hot spots. Vibration analysis checks for strange shaking in undercarriage parts, helping you find roller and idler problems before they get worse. These tools make maintenance easier and help you avoid expensive breakdowns.
Diagnostic Tool | What It Does | Where To Use It |
|---|---|---|
Ultrasonic Testing | Finds cracks and thickness changes | Rollers, tracks, sprockets |
Thermal Imaging | Shows overheating parts | Bearings, bushings |
Vibration Analysis | Checks vibration levels | Undercarriage parts |
Plan regular checks
You should follow a strict schedule to keep your excavator in good shape. Daily checks are important. Weekly checks help find problems that take time to show up. At 500 hours, change oil, fuel filters, and service belts. Change engine oil every 250 to 500 hours. Change hydraulic fluid and coolant every 1,000 to 2,000 hours. Following this schedule lowers the risk of breakdowns and makes your machine last longer.
Tyler Smith, Product Manager – Training at Volvo, says to follow the OEM service plan. This plan includes daily checks and maintenance at certain hours.

List of excavator parts to check
When you check your excavator, look at every part that works hard. Each part can get worn out, so you need to look closely and fix problems fast. Use this checklist to help you keep up with maintenance and make your machine last longer.
Engine parts (YNF Machinery Excavator Engine Parts)
Engine parts make your excavator move. Check pistons, cylinders, crankshafts, and bearings for cracks or leaks. Look for dirty fluids and signs of too much heat. Rubber mounts can get hard or swell from heat or leaks. If you see damage, change these parts with good ones from YNF Machinery. Their engine parts help stop breakdowns and keep your machine working well.
Failure Point | Description |
|---|---|
Environmental Exposure | Heat and ozone can make rubber crack and break. |
Fluid Contamination | Leaks can make mounts swell and get weak. |
Impact and Overload | Heavy loads can rip or break engine mounts. |
Hydraulic components
Hydraulic pumps, control valves, cylinders, hoses, and fittings need regular checks. Listen for odd sounds and look for leaks. If the machine moves slowly or jumps, parts may be worn. Check for overheating and low pressure. Change any bad parts right away to stop bigger problems.
Hydraulic pumps
Control valves
Hydraulic cylinders
Hoses
Fittings
Undercarriage parts
The undercarriage holds up your excavator and takes a lot of stress. Look at track links for cracks or missing pieces. Check rollers for a strange shape or leaks. Look at idlers for wear and listen for noise. Sprockets should not have hooked teeth. If the machine moves unevenly or slowly, the undercarriage may have problems. Change worn undercarriage parts fast to avoid big repairs.
