Keep reading this article to find out more.
1. How Does A Mini Excavator Final Drive Work?
The mini excavator final drive is divided into two parts:
-Gearbox
A mini-excavator has a pair of mini final drive motors. The hydraulic travel motor converts hydraulic energy coming from the main hydraulic pump to spin a rotating group. Then, the rotating group engages a robust shaft that runs across to the gearbox.
Here, the mini final drive gearbox reduces speed coming from the robust shaft using planetary gear configuration. It relatively increases the available torque which spins the hub which the track sprocket is mounted on. This then allows the machine to move in the direction you desire.
2. Which is the Best Mini Excavator Final Drive to Buy?

3. Why Does My Mini Excavator Final Drive Heat Up?
Whenever your mini final drive starts heating up, there might be several issues leading to that. You need to do some troubleshooting.
Check this out:
1.You need to first check your mini final drive gearbox oil level. If your gearbox oil level is low, it means that there is friction between contacting parts – there is no proper lubrication. If the oil level in your gearbox is low, there might be a leak in your final drive.
You can decide to temporarily solve the issue by topping your gearbox oil level. However, you’ll need to look for a permanent solution that will lengthen your mini final drive’s lifespan.
2. If your gearbox oil level is okay, the second thing that you need to check should be the hydraulic fluid. The standard hydraulic fluid temperature should not be more than 180°F. Should the hydraulic fluid be hotter than that, then you need to know that there is an issue with your hydraulics.
Consider checking your hydraulic system and the hydraulic fluid cooler.
3. If the gearbox oil level and the hydraulic fluid temperature are both okay, consider checking your brakes. The brakes need to be releasing properly. If they are not, that means that there will be an increase in heat.
Consider checking your brake operating pressure as well as the piston seals.
You should also contact a professional to help you diagnose the issue. Not only will it save you time, but also lengthen the lifespan of your mini-final drive. KS can help you out with professional advice. We also have over 10,000 excavator parts in stock ready to ship, just in case you have to buy new parts to solve the overheating issue.

Our packaging also ensures that your excavator parts reach you safely. We pack your parts in sturdy carton boxes, and then enclose them in rigid wooden boxes.
4. Which is the Best Oil To Use for My Mini Excavator Final Drive?
You need to use SAE viscosity grade oil for your mini excavator final drive. your final drive gearbox oil should have its optimum viscosity grade. The “W” stands for winter viscosity grade, meaning that your gearbox oil underwent colder tests.
Check out SAE viscosity grade table:

5. After How Long Should I Service My Mini Excavator Final Drive?
Servicing your mini excavator’s final drive helps you have a stronger mini final drive with a longer lifespan. It’s a proper maintenance practice.
Here’s the deal:
You need to service your final drive after every 1000 hours of work, or after every six months, whichever comes first. Whenever you service your mini final drive, you need to replace the oil in both final drive cases.
You also need to drain and flush your cooling system – and replace it with a new coolant. You also need to replace your hydraulic fluids and filters.
6. How Are Final Drives Connected in A Mini Excavator?
Now, a mini final drive can have up to five lines to your mini excavator. You’ll find out that different models have either 2, 3, 4, or even 5 lines. Each connection has its purpose, and you should not confuse them. These lines are known as the flow and return lines.
Once you confuse them, the mini final drive will not work properly.
- Mini Final Drive Case Drain Lines
If you find more than two lines present in your mini excavator’s final drive, one of those lines is a case drain line. All mini final drives have a rotator group. This rotator group leaks oil to all the piston-type hydraulic motors. This leakage is intended to lubricate the thrust plate, cylinder block, piston shoes and the valve plate.
The primary purpose of this line is that it returns the leaked oil oil to the hydraulic tank under low pressure.
Check this out:
If your mini final drive has only three lines, the smallest among them is definitely the case drain line. There are some mini final drives that have two case drain lines. KS experts recommend using the highest case drain port to cater for proper air circulation of the mini final drive.
- Mini Final Drive Case Drain Lines
You need to know your mini final drive’s model. A two-speed motor will have two-speed lines. Their primary purpose is to help hydraulic fluid flow in the motor whenever the machine is set on high-speed mode.
- Mini Final Drive Brake Line
You can also find a brake line on your mini final drive motor. You’ll most likely find it behind or on the side of the primary housing.
The flow and return ports are marked A and B above. The final drive also has drain case ports marked C1 and C2. As stated earlier, the flow and return ports are bigger than the drain case ports.
KS understands that these mini final drive lines can confuse you. That is why we have highly skilled and trained service reps ready to listen to you at any time.

Final drives for mini excavators can last longer only through proper care and maintenance. This means that you always have to be keen on key issues which include:
-Proper gearbox oil level
-Proper hydraulic fluid level and temperature
-Proper service after the recommended duration
Once you realize that there is an issue with your mini final drive, please contact a professional to help you diagnose the issue.
