Hydraulic Filters
Function
Hydraulic filters keep the hydraulic system safe. They catch dirt and metal pieces before they reach important parts. Clean filters help the machine work well. This means better performance and fewer problems. Dirty filters can lower pressure and slow the excavator. You might hear odd sounds or see leaks if filters get blocked. Always use the right filter for your machine to keep it safe and working well.
Replacement Tips
Check your hydraulic filters often. Most brands say to change them every 1,000 hours. Some machines need new filters after only 250 hours. This is true if you work in dusty or rough places. Watch for these signs that filters need changing:
The machine loses power or moves slowly.
The flow rate drops or pressure goes down.
You hear strange sounds or see leaks.
Tip: Always read your excavator’s service manual for the right schedule. Changing filters at the wrong time can cost a lot to fix.
Here is a simple guide for filter care:
Service Interval | Hydraulic Filter Maintenance |
|---|---|
250 hours | Change hydraulic filter element |
1,000 hours | Replace hydraulic filters (general recommendation) |
2,000 hours | Change hydraulic oil and filter |
Keeping extra filters in stock helps you avoid delays. You can keep your excavator ready for work when you have the right parts.
Bucket Teeth
Wear and Replacement
Bucket teeth help your excavator break hard ground and move heavy stuff. These teeth get hit hard and scraped a lot as you work. The tips of the teeth get the most damage first. If the teeth are not strong enough, they might bend or change shape. When digging deeper, teeth rub against rocks and concrete. This makes deep scratches and wears them down.
Some things that wear out teeth are:
Hitting hard things
Rubbing on rough stuff like rock or concrete
Bad material or no heat treatment
If teeth get dull, chipped, or cracked, digging gets harder. Your excavator will use more fuel and work slower. Check the teeth often. Change them if you see deep lines, broken tips, or if they do not cut well. Teeth made from strong alloy steel or tungsten carbide last longer. They help your machine work better.
Tip: Look at your bucket teeth after every shift. This is very important if you dig in rocky or rough places. Changing teeth early stops bigger problems and keeps your excavator working.
Compatibility
It is important to pick the right bucket teeth for your excavator. Not every tooth fits every bucket or machine. You must match the size, shape, and how the teeth attach to your equipment. Wrong teeth can make digging bad and might hurt your bucket.
Manufacturers make different teeth for different jobs. Some teeth are for normal digging. Others are for rock or frozen ground. Always check your operator’s manual or ask your parts supplier before buying new teeth. This helps you get the right teeth and the best results for your work.
Note: Keep extra sets of the right bucket teeth in your stock. This helps you change them fast and avoid waiting when you need new ones.
Track Chains
Maintenance
Track chains play a key role in your excavator’s movement and stability. You need to keep them in top shape to avoid costly repairs and downtime. Start by cleaning your tracks after every use. Remove rocks, mud, and plants that can get stuck between the links and track pads. This simple step helps prevent extra wear.
Check your tracks often for cuts, tears, or signs of heavy wear. Look at the rollers and idlers, and make sure you lubricate them well. Proper lubrication keeps the chain moving smoothly and reduces friction. You should not worry about over-lubricating—more is better than less.
Always adjust track tension to match the manufacturer’s guidelines. If the chain is too loose, it may jump teeth. If it is too tight, it can cause damage. Make sure the sprockets line up correctly in both the axial and angular planes. Poor alignment puts stress on the chain and shortens its life.
Tip: Train your operators to avoid sharp turns, spinning, and high speeds on hard surfaces. These actions wear out the track pads and chains much faster.
Choose the right track pads for your job and terrain. The correct pattern helps your tracks last longer and gives you better traction.
Stocking Advice
You should keep extra track chains and track pads in your parts inventory. This helps you replace worn parts quickly and keeps your excavator working. Stocking the right parts means you do not have to wait for deliveries when something breaks.
Inspect your inventory often. Check for missing or damaged parts. Keep a record of how often you replace track chains and track pads. This helps you plan your orders and avoid running out.
Note: Always buy genuine parts from trusted suppliers. Quality parts last longer and fit your machine better.
A good stocking plan saves you time and money. It keeps your excavator ready for any job.
Air Filters
Importance
Clean air filters help your excavator’s engine work well. They stop dust and dirt from getting inside the engine. If you use your machine in dusty places, filters can clog faster. When you wait too long to change filters, dust can get into the engine. This can wear out parts, lower power, and use more fuel. You might have to pay more for repairs and fix breakdowns more often.
If you do not take care of air filters, the engine can get too hot or stop working. Checking and changing filters on time saves money and helps your equipment last longer.
Good air filters let air move the right way. This helps the engine burn fuel better and keeps the excavator running smoothly. You will not have to pay for big repairs and your work will stay on track.
Replacement Schedule
You need to follow a simple plan to care for air filters. Most people say you can clean the outer filter up to six times before getting a new one. After 1,000 hours, change both the outer and inner filters at the same time. If you work where it is very dusty, check and change filters more often.
Use compressed air to clean the outer filter, but do not get too close or you might break it.
Never clean the inner filter. If you see dust or damage, put in a new one right away.
Always look for clogs or worn spots when you check your machine.
Tip: Always follow the rules from your machine’s maker. Change your plan if you see more dust or tough work at your job.
Changing filters on a schedule keeps your engine safe and your excavator ready to work.
Belts
Common Issues
Belts play a vital role in your excavator’s performance. You rely on them to drive fans, alternators, and hydraulic pumps. Over time, belts can crack, fray, or stretch. Heat, dust, and vibration speed up this wear. If you hear squealing or see slipping, you may have a worn belt. A loose belt can cause poor power delivery. A broken belt can stop your machine and lead to costly downtime.
You should check belts for signs of damage during every inspection. Look for glazing, missing chunks, or uneven wear. If you see any of these problems, replace the belt right away. Ignoring these signs can lead to sudden breakdowns. You can avoid bigger repairs by acting early.

Note: Clean fluid and good assembly help seals last longer. Good habits save money and protect your excavator.
Hoses
Inspection
You need to inspect hoses on your excavator often. Hoses carry hydraulic fluid under high pressure. If a hose fails, your machine can stop working. You can prevent most hose problems by following a regular inspection schedule:
Check hoses every day. Look for cracks, leaks, or bulges.
Inspect hydraulic hoses each week. Focus on signs of wear, damage, or leaks. Replace any hose that looks bad.
Every month, check the whole hydraulic system. Listen for strange noises or feel for vibrations. These can mean a hose is about to fail.
You should know the main reasons hoses fail. The table below shows common causes and how you can prevent them:
Cause | Description | Preventative Measures |
|---|---|---|
Heat Aging | High temperatures make hoses hard and cracked. | Move hoses away from heat. Use heat shields. |
Abrasion | Hoses rub against parts or other hoses and wear out. | Reroute hoses. Add covers or shields. |
Site Damage | Sharp objects like rebar or concrete cut or tear hoses. | Use shields or covers to protect hoses. |
Hydraulic Contamination | Dirty fluid with sharp bits damages the inside of hoses. | Keep fluid clean. Watch hose condition. |
Wear and Tear | Hoses wear out from pressure cycles, not just hours of use. | Inspect often. Replace hoses that show any failure. |
Tip: Early detection of hose problems helps you avoid costly breakdowns and keeps your excavator running.

Undercarriage Parts
Wear Points
The undercarriage has many parts that wear out fast. You need to watch rollers, idlers, sprockets, and track pads. These parts get hit by rocks and dirt all the time. Heavy loads and rough ground make them wear out even faster. Dirt and rocks rub against these parts and cause deep marks. Over time, this makes the parts wear unevenly. If you do not check often, you might miss broken or missing parts. Oil leaks from rollers or idlers mean the seals are bad. Leaks can cause big problems and cost a lot to fix.
Bad driving habits make parts wear out faster. Driving backward fast, turning sharply, or working on slopes without balance can make parts wear out three times faster. If tracks slip more than 5%, you will spend more on repairs and fuel. If you do not clean mud and dirt after each shift, your machine can break down sooner. Training operators to check parts and use good habits helps stop these problems. Finding issues early lets you fix them before they get worse.
