Studies show daily cleaning can lower equipment failures by 30%. Cleaning also helps you find problems before they get worse. You save money and your excavator lasts longer. Cleaning and checking the undercarriage every day is the best way to stop downtime.
Note: Cleaning the undercarriage is not just for looks. It helps with safety, saves fuel, and makes your machine last longer.
Inspect Excavator Track Motor

Check for Wear and Leaks
You should check your excavator track motor every day. Look at it before you start work. See if there are oil spots under the excavator after it sits overnight. Oil spots can mean leaks in the hydraulic or gear oil systems. Listen for strange sounds like grinding, squeaking, or knocking. These sounds can mean parts inside are worn out.
Check the fluid levels during your inspection. If the hydraulic fluid or gear oil is low, it can hurt the system. Look at hoses and fittings for cracks, bulges, or if they are loose. Wipe seals and hoses with a cloth to get rid of dirt. This makes it easier to see leaks. If you find leaks, tighten any loose parts or change broken seals and hoses right away. Watch the final drive oil levels to stop overheating and breakdowns.
Tip: Checking the whole undercarriage helps you find leaks and worn parts early. Finding problems early saves money and keeps your excavator working longer.
Key indicators of wear and leaks:
Strange noises from bearings or hydraulic pumps.
Fluid leaks under the excavator.
Cracked or loose hoses and fittings.
Worn seals or gaskets.
Low fluid levels.
Oil marks behind gears or drops on tracks.
Spot Loose or Damaged Parts
Look at the undercarriage for loose bolts, broken track shoes, or missing parts. Use your eyes to check if everything is there. If you hear odd noises, try to find where they come from. Take off covers or anything in the way to see better.
If you find loose or broken parts, stop using the excavator right away. Get repairs or new parts before you use it again. Look at the operator manual if you need help with where parts go. A full check makes sure all parts are tight and no debris is left.
Note: Checking and fixing things often stops big repairs. Look at the undercarriage every day to find problems early.
Checking the undercarriage and doing daily checks help keep your excavator track motor working well. Acting early protects your machine and stops downtime.
Maintain Track Tension
Prevent Premature Wear
You should check track tension often. If you do not, your excavator can wear out quickly. Loose tracks can slip and rub on other parts. Tracks that are too tight put extra stress on the motor and other parts. Both problems make your excavator not last as long.
Here is what the manufacturer says about track tension and its effects:
Aspect | Details |
---|---|
Impact of Improper Track Tension | Causes more wear, stress failures, uneven wear, slippage, and shorter lifespan of motors |
Lifespan Improvement | Proper tension can improve track lifespan by up to 23% |
Manufacturer Specs | Sag should be 10-20mm; adjust tension for mud or hard ground |
Consequences of Incorrect Tension | Slippage can increase fuel use by 18% and speed up wear |
Maintenance Recommendations | Inspect and adjust tension regularly to factory specs |
Warranty Implications | Damage from bad tension may not be covered by warranty |
Keeping the right track tension saves money. It also helps your excavator last longer. Always follow the manufacturer’s rules for sag and tension.
Tip: Check track tension before you start a new job. If you see tracks slipping, check them right away. Daily checks help you find problems early.
Adjust as Needed
You can fix track tension with easy steps. Follow these to keep your excavator working well:
Look at the track adjuster and grease cylinder for dirt or damage.
Clean the grease fitting (Zerk) and make sure it works.
Add grease to the adjuster to move the front idler out and tighten the track.
To make the track looser, let grease out by loosening the fitting. Sometimes you need a pro for this.
Measure the sag between the middle roller and the track. Most machines need 15-30 mm of space.
Change the tension for the ground. Use tighter tension on hard ground and looser on soft ground.
Always wear safety gear and park on flat ground before you adjust.
Check for worn links or stretched tracks. These can stop you from adjusting more.
Check track tension at least once a month. Many people check it every day or every 50 hours. Regular checks stop slippage, lower wear, and keep your excavator safe.
Note: If the track is too tight, it can wear out faster and slow your machine. If it is too loose, it can come off and break things. Always use the operator’s manual for the right way to adjust.
Lubricate Daily
Pins and Bushings
You need to lubricate pins and bushings every day. These parts move a lot and carry heavy loads. Without enough grease, they wear out fast. Friction builds up and causes metal parts to grind against each other. This leads to cracks and even metal fatigue. You might see cracks at weld seams or near the boom. If you ignore these signs, the damage can become dangerous.
Tip: Always use the grease recommended by your manufacturer. High-quality grease protects pins and bushings from dirt, water, and heat.
Neglecting daily lubrication can cause:
More friction and faster wear on pins and bushings
Extra movement in joints, making them loose
Cracks and metal fatigue from stress
Premature failure of important parts
Higher repair costs and more downtime
Proper lubrication also helps your hydraulic system. Greased pins and bushings reduce strain on hydraulic cylinders. This keeps your excavator running smoothly and extends the life of your hydraulic components.
Grease Points
You should check and grease all critical points on your excavator every day. Important grease points include boom pins, stick pins, bucket pins, and track drives. These areas face the most stress and need extra care. If you miss daily greasing, you risk permanent damage. Repairs for these parts can cost thousands of dollars.
A simple daily routine can help:
Wipe off old grease and dirt from fittings.
Apply fresh grease until you see a small amount coming out.
Use the right pressure to avoid damaging seals.
Pay special attention to the track drive and hydraulic connections.
Note: Using high-quality grease and following the right schedule keeps your excavator safe. It also prevents metal-on-metal contact, which can destroy bearings and track motors.
Field studies show that proper lubrication greatly reduces wear and tear on track motors. Clean grease keeps out dirt and metal particles. This protects your hydraulic system and moving parts. When you keep up with daily greasing, you lower the risk of breakdowns and save money on repairs.
Grease Point | Why It Matters | How Often |
---|---|---|
High stress, costly to fix | Daily | |
Stick Pins | Frequent movement | Daily |
Bucket Pins | Heavy loads | Daily |
Track Drives | Protects track motor & hydraulic | Daily |
Monitor Wear Patterns
Identify Misalignment
You can find misalignment by checking wear on the tracks. Look at both sides of the track links. If one side wears down more, the undercarriage may not be lined up. Inside edge wear means the track or undercarriage needs to be fixed. Sprocket misalignment can make the track come off or wear out fast. If idlers wear unevenly, there could be a misalignment problem.
Tip: Take pictures of the undercarriage and track wear every month. Compare these photos to see changes and spot misalignment early.
Checking often helps you find problems before they get worse. Watch for strange shaking or track sag that is not even. These signs can mean misalignment. If you see scalloped or uneven wear, check all undercarriage parts for alignment.
Common wear patterns and what they mean:
Too much case drain and scratches inside: Dirty oil, less power, slow track speed.
Worn gears and bearings: Loud screeching, slow movement.
Oil leaks and pressure loss: Broken seals, weak motor performance.
One track moves faster: Stuck spools or pistons, two-speed system problems.
Address Issues Early
Act quickly if you see strange track wear or misalignment. Fixing problems early saves money and keeps your excavator working. If you hear grinding or whining, stop the machine and check the drive case. Look for gear alignment problems or worn parts. Fix or replace gears if needed.
Follow these steps when you see early signs:
Check hydraulic fluid levels on flat ground. Add the right fluid if needed.
Look at the motor for damage or loose parts.
Drive the excavator and watch for steering or power problems.
Fix leaks by tightening parts or changing seals and hoses.
Clean the undercarriage to stop debris from causing more damage.
Watch speed, power, and fluid levels to catch problems early.
Note: Finding track slippage, uneven wear, or leaks early lets you fix problems before they get worse. Keeping the undercarriage clean and checking for wear helps you avoid big repairs.
A simple table helps you track common issues:
Symptom | Possible Cause | Action Needed |
---|---|---|
Uneven track wear | Misalignment | Realign components |
