The excavator final drive is composed of 8 elements: engine, gearbox, reducer, chain drive, track rollers, suspension axles, idler axle, and finally, the wheel sprocket.
The complete construction is assembled with these elements to make it work as a perfect machine.
Excavator final drive works on the power transmission principle from the fuel engine through a motor to the wheels (or tracks) of an excavator.
The engine power is applied to the main drive shaft connected to an input gearbox containing several gears by a union joint.
The power is transmitted through chains that are wounded on gears and sprockets.
In an excavator gearbox, there are several components that allow the high temperatures generated by the engine to cool and also to protect the hydraulic pumps and motors.
13. How to change excavator final drive bearings?
The bearings are typically located in the bottom of the gearbox either under the center housing (in most cases) or outboard of the sides at the bottom due to space restrictions or turtling of the main gear.
- The first step is to loosen the rear cover of the unit and then remove it.
- After removing the screws that secure the outer bearing housing assembly, remove it.
- The oil seal on the outside of the input shaft should be removed by twisting it.
- Then remove the gears and sprockets mounted on the circular shaft.
- With the help of appropriate tools, take out bearings from inside the circular shaft and replace them.
In most cases, the bearings fail due to overheating and lack of lubrication.

- Take the weight, drop it, and move on.
- When it comes to hoses, it’s essential to know the difference between them and later identification during assembling.
- The most important thing to do is to remove the hoses from their fittings and put everything back in its proper place.
- From inside the track frame, pull the final drive apart from the frame by removing bolts.
15. What kind of oil goes in an excavator final drive?
If you are looking for the proper lubricant for your final excavator drive, you must pick the oil based on your excavator’s make and model.
Drive motors fall into two categories: electric and hydraulic. The oil should include a flush asset that gets rid of any existing oil in the equipment to avoid incompatibility issues.
An excavator travel motor requires more than just one type of oil, especially in its different subsystems.
The oil that goes in the final drive of an excavator is mineral-based, S.A.E. grade 80 with a pour point lower than -30°F (-34.4°C) and a viscosity index of 150 or greater.
A typical specification for an excavator may read. “The final drive gear lube shall have a pour point below -30°F (-34.4°C) AND 150 VI”.
Some lubricants will add seal swell protection and corrosion inhibitors as needed based on the Excavator, application, and operating environment location.

Additional reasons: The final drive fails to include unprofessional repair, less budget, not using a genuine part, and failure.
20. How to replace excavator final drive hydraulic lines?
Excavator final drive hydraulic lines must be replaced or rebuilt as soon as signs of leakage begin happening.
Leaking lines can lead to a host of other issues with the machine.
When hydraulic lines are moving and flexing, wear is inevitable, and they will wear out over time due to their constant motion in use.
The first step is to remove all the oil present in your final drive.
The second step is to unscrew all bolts that are holding hydraulic hoses in place.
After removing hydraulic hoses, take out hydraulic lines and examine the leakage point.
Replace the old one with a new one and fix them by screwing hydraulic hoses.
Fill the oil up to the desired level.
Start your final excavator drive and observe one final time.
21. How to change oil for the excavator final drive?
In case you are going to replace the oil, then do it when the temperature of the oil is more remarkable because the density is low, and the whole oil quickly gets drained at a higher temperature.
Lose the plugs and remove any dirt or contaminants around them.
