Badanie wycieków oleju z przekładni głównej
Wprowadzenie
The final drive is built to work in rough conditions, but oil leaks are something many operators overlook. If you ignore the early signs, the machine won’t just lose performance—it can also break down and leave you stuck with costly downtime.
Main Causes of Final Drive Oil Leaks
Damaged Seals
The seals keep the oil inside the drive. With time they get hard, crack, or wear out—especially if the machine runs in dust and dirt every day.
Bearing Wear
When bearings wear down, they don’t fit right anymore. That extra play lets oil sneak out under pressure.
Housing Cracks or Impact Damage
A rock hit or constant vibration can crack the housing. Once that happens, oil starts leaking out.
Poor Oil or Too Much Pressure
Cheap oil or the wrong grade breaks down fast. Day after day, pressure stress on the seals and gears, which often leads to leaks.
Risks of Oil Leaks
Unexpected Downtime
Even a small leak can drain oil until the drive runs dry, and then the machine is out of action.
Gear and Bearing Damage
Without enough oil, the parts inside wear out in no time.
Overheating and More Fuel Use
Low oil makes the drive run hot, and the machine ends up burning more fuel.
How to Check the final drive Leak
Look Around
Check the track area and the ground under the machine. Fresh stains usually mean oil is coming out.
Watch While Running
If you see smoke or feel the machine losing power, the drive might be leaking.
Check Oil Level
If you keep adding oil more often than normal, something inside is letting it escape.
How to sovle Oil Leaks
Minor Leaks
Swap out bad seals and top up with the right hydraulic oil.
Moderate Leaks
Check bearings and gears. Replace worn parts and make sure everything lines up right.
Severe Leaks
If the housing is damaged or too much wear on it, the best way is to change the whole final drive. Use original Komatsu, Caterpillar, or Perkins parts will give you a reliable quality.
Preventive Measures
Check and change oil and filters on schedule.
Stick to oil that meets the maker’s specs.
Don’t overload the machine.
Use original parts so the seals stay tight.

Oil leak looks like a small problem, but if you ignore it, it will turn into a big problem. Know the reason, care of early signs, and fix them before they cause bigger trouble.
