I'm looking at buying a used KS 120 eb that the seller has a bad motor.  Does anyone know the part number for a replacement?  Looks like a common problem and maybe I can get the newer updated motor?  Thanks
 
I am hoping to just buy the motor and not have to pay to ship it in and labor.  The saw is $600 before I do any repairs.
 
I would test it before purchasing parts that may or may not be bad. 

Suppose it's not the motor?

Best of luck
 
You can call Festool to order the motor. They are the only place you can get a genuine replacement motor from. So, even if you knew the part number, you'd still have to get in touch with them.

I don't have the part number, otherwise I'd share it with you. I understand there's a ekat website that has replacement parts, so, you can search that. But it would be simple enough to pick up the phone and talk to someone at Festool, and place an order while you're at it. If you're not ready to order, it's still ok. The guy on the phone should have the part number, and more answers for you. 🤷🏾‍♂️
 
Look the saw over thoroughly and make sure nothing is damaged:
1. Is the fence straight
2. Does the table move easily
3. Are there damaged plastic pieces
4. Does anything appear bent?
5. Is there a blade on the saw and what condition is it in?
6. Yada, yada, yada

Through some careful observation and some playing with the moving parts you want to determine if the saw was just used or was it abused? If all it needs is a new motor that's relatively cheap, around $200. If however it also needs plastic guards, a new fence, linear bearings etc, that bill can start to approach $600 or more.

Don't forget it could also be the brushes just need to be changed out for around $50.

As already mentioned I'd also plug it in and see what happens...if the motor is toast the damage is already done.  [smile] Does the motor turn slowly and is there a smell, then it's probably the motor.

Does the motor not rotate at all and only buzzes, then it's probably the brushes.

I got the saw and it turns on but the blade spins slowly and there is a bit of a smell.  The seller mentioned something about smoke coming from the motor at one point so I'm guessing it's a bad motor.  Just need to figure out the right part number and get one ordered.
