- Know the importance of the excavator slew motor
- Know how to maintain your excavator slew motor properly and how to repair or replace it
Keep reading this article to find out more about your excavator slew motor.
1. What Is An Excavator Slew Motor?
An excavator slew motor is also known as an excavator swing motor. It works closely with the slewing bearing to move the excavator. Slewing means to rotate without changing position.
An excavator can rotate countless times (360°) without the undercarriage changing its position as the excavator works.
If you are looking for an excavator slew motor, KS is here to help you. We can provide you with any excavator’s brand slew motor that you need. KS manufactures Komatsu, CAT, Volvo, Doosan, Hyundai, Kobelco, Hitachi, and other brands’ slew motors.
These slew motors are covered by a 90-day warranty period. Reach out to us today for more information on your excavator slew motors.
2. Where Is An Excavator Slew Motor Found In An Excavator?
An excavator slew motor is found on the right-hand side of the excavator, just behind the excavator’s cabin for standard (in terms of size) excavators. It then extends vertically between the cabin and the undercarriage.
The slew motor is what rotates the slewing bearing so that the excavator can slew around.
Check this out:
Depending on the make and model of your excavator, slew motors are found where the slewing bearing has gears. These gears help the slew motor move the slewing bearing so that the excavator can turn 360°.
3. How Does An Excavator Slew Motor Work?
An excavator slew motors work by using hydraulic pressure to slew the excavator. Depending on the direction of travel from the excavator’s operator, the slew motor can rotate the excavator either left or right.
Watch this short video to understand this concept better.
4. What Are The Components Of The Excavator Slew Motor?
An excavator slew motor is made up of gears, bearings, rings, bolts, seals, and gaskets that work together as a unit.
Our company will supply you with the recommended excavator slew motor components, with no minimum order quantity (MOQ).
You’ll only need to contact us through our website and share with us what you require together with your estimated budget. We’ll respond with a solution that meets both your requirements and your budget.
You can check your excavator slew motor parts in this short animated video. The video will help you know these parts better and how they fit in each other, especially if you want to replace them.
5. What Is The Difference Between A Slew Motor And A Travel Motor?
As you read earlier, a slewing motor is found between the undercarriage and the cabin area. It is used to swing the excavator with the help of an excavator slewing bearing.
An excavator travel motor, on the other hand, is found in your excavator’s final drive. A travel motor consists of a hydraulic motor driving a planetary gearbox with the drive sprocket mounted to it.
6. How Is A Slew Motor Installed In An Excavator?
Installing a slewing motor in your excavator is a rather straightforward process. You’ll only need to make sure that you have secured the slew motor properly, as it is quite heavy so that it does not fall on you.
You can use a lifting machine, like a pulley, to hold it in position. You’ll then align the slew motor’s gears with the excavator’s swing bearing at the base. Remember that these two work hand in hand to slew the excavator in the operator’s desired direction.
Once they are aligned, you’ll need to lower the slew motor slowly, ensuring that it goes into its housing. It would be best if you did this activity with another person to help guide the slew motor to the housing where its gears are aligned with the slewing bearing.
Once the slewing gear is inside the housing and its gears are aligned to those of the slewing bearing, you’ll need to bolt it down properly so that it sticks in that position. Ensure that you use clean bolts that do not have grease. They’ll offer a better grip. Ensure the bolts are tightly fixed.
After bolting it down, you can then start fixing hydraulic hoses to the correct ports, as shown in your excavator’s service manual.
Ensure that you complete the above process with a certified professional. Doing it on your own without proper permits could damage your excavator’s slew motor. It can also void your warranty coverage.
7. How Can I Replace My Excavator Slew Motor Seals?
Excavator slew motor seals will require replacement after some time. They’ll eventually wear out.
Replacing your excavator slew motor seals will require you to open up your excavator slew motor.
Here’s what you should be prepared for:
You’ll need to be prepared to get your hands dirty – literally. The process will be oily, full of hydraulic fluids. Remember that faulty excavator slew motor seals leak hydraulic fluid.
Since the machine is tightly fixed, you’ll require disassembly tools. After you complete disassembling the excavator slew motor, you can get rid of old sticky hydraulic fluids using a grease remover to ensure that installation happens on a clean surface.
Clean all the parts properly to remove old hydraulic fluids.
Check out this short detailed video. It’ll show you how to replace your excavator slew motor on your own.
Remember to contact a certified professional to help you out in this process.

8. How Can I Know If My Slew Motor Is Bad?
Your slew motor is bound to get damaged due to natural wear as it works. This natural wear makes your excavator’s slew motor get damaged over time. In other situations, your slew excavator motor will prematurely fail – especially if you did not take care of them.
The first sign that your slew motor is bad is leakage. Leakages signify that there is a problem with your excavator slew motor seals. You’ll need to replace them with new ones to do away with this problem completely.
Also, ensure that you’ll install your slew motor’s seals correctly. Do not let them get cut as they will not last for long.
The second reason why your excavator slew motor leaks are because of excessive case drain from the motor. It is brought by constant wearing out of your excavator’s slew motor. This cause is enhanced, especially when the slew motor has contaminated oil or when it overheats.
The third reason why your excavator slew motor leaks are because of the output bearing failure. When your bearings fail, your excavator slew motor’s oil will leak the motor oil beyond the output seal as the excavator slew motor’s shaft is already misaligned.
You can prevent the above problems by constantly checking your excavator’s slew motor and gearbox oil condition and level. It would help if you also cleaned the device’s oil cooler. If possible, you should also.
The second sign that’ll show you if your slew motor is bad is when it has excessive play. Excessive play is brought by wearing out of parts over time. You’ll need to replace excessively worn-out parts to reduce your excavator slew motor play.
You’ll also find out that your excavator slew motor will be sluggish in case it is bad. The reason why it becomes sluggish is that the rotating group is worn out. You’ll also learn that the rotating group is worn out when the excavator takes longer to stop slewing.
9. Why Does My Excavator Slew Motor Leak?
Your excavator slew motor leaks because there is a problem that needs to be fixed urgently. There are top 3 reasons why your excavator slew motor leaks. Check them out:
The first reason is that there is a large amount of case drain from the motor. The case drain leaks because of wearing out of the rotating group inside the excavator slew motor. The rotating group is the most hardworking part of the excavator slew drive.
Once the excavator slew motor starts working, the rotating group heats up. When heat increases, the rate at which these parts wear out also increases. You can solve this problem by replacing the rotating group and installing new seals.
You’ll only install a rotating group once you find out that they are completely worn out. If they are not worn out, consider installing new seals only.
The second reason why your excavator slew motor leaks are simply because of damaged seals. It’s a common problem for all seals to fail at some point in their service life because of wearing out.
Ensure that your excavator slew motor does not overheat, as overheating enhances wearing out of your seals. Overheating further makes your excavator’s slew motor’s seals brittle, meaning they can get cut quickly or they can allow oil to leak through them.

11. How Can I Remove My Excavator Slew Motor?
Removing your excavator’s slew motor is a pretty straightforward process. It’s important to put your excavator in safe mode so that you can start repairing it. You’ll need to refer to your service manual on how you can do that.
After putting your excavator in safe mode, you’ll need to locate your excavator’s slew motor on your excavator. After finding it, you’ll then disconnect its hydraulic hoses and ensure that no dirt enters your hydraulic system through these hoses. In other words, you’ll need to secure them properly.
After detaching the hydraulic hoses, you’ll then proceed to untighten the bolts that hold your excavator slew motor in place. Keep each bolt safe as you continue unbolting so that you do not lose any of them.
Now, since most excavator slew motors are heavy (except mini excavators), you’ll require another heavy machine to help you lift the excavator slew motor out. You can use a mini excavator to help you.
Remember to secure the excavator slew motor properly before lifting it from the excavator. Securing it will prevent accidents and serious bodily injuries.
12. How Is The Excavator Slew Motor Connected To The Swing Bearing?
Your excavator slew motor is connected to the swing bearing by gears. When installing your excavator slew motor, you’ll need to ensure that both the excavator slew motor and the swing bearing gears align.
Apart from that, you’ll need to ensure that your slew motor’s hydraulic connection is done correctly, as it will significantly affect your excavator’s performance.
This alignment will prevent any gear damages. It would be best if you remembered that the excavator slew motor is what drives your excavator’s swing bearing. When they work in unison, the excavator cabin can slew.
13. Which Oil Should I Use For My Excavator Slew Motor?
It would be best if you’d use the recommended type of excavator slew motor as specified by your excavator’s manufacturer. It is imperative to do so because there are different makes and models of excavators in today’s market.
If you cannot find the recommended one, you can contact a professional and reputable company to help you out. KS service reps are always available to listen to you and help you out.
14. What Should I Do If My Excavator Slew Motor Fails To Start?
In the event your excavator’s slew motor fails to start, you’ll need to halt your excavator immediately. An excavator cannot work without a slewing motor, meaning it is impossible to operate the excavator.
Your excavator slew motor does not start mainly because the rotary lock valve is damaged. You’ll need to repair your excavator’s slew motor damaged parts by replacing the rotary lock valve.
