Very thorough step by step video. Easy to follow along. Thanks, your video made the difference!!
Excellent video thank you very detailed very helpful
This was very very helpful. Thank you. I am planning to change the grease of the gear mechanism between the two top bearings. What kind of grease should I use? The reason I ask is because I used NLGI 2 grease, different type and they all flew out of the casing making a mess. I figured one need to have a much thicker grease to stay in the enclosure between the two bearings, to keep grease on the gears.
The bearing puller has two 2 extra holes on the flat surface for the puller bolts and one for the pointed
center shaft. Once everything is complete, you just tighten clockwise your center bolt and you will see that bearing will come out.
Thanks for sharing your knowledge
Lot of work on your part to make a good video. Very Instructive, especially on the small stuff that would normally be left out. That really helps.
BTW... WHAT was the chunk of plastic that made the motor stop turning ??
This is the best video I have seen yet on this problem. I just removed the melted plastic tonight and tomorrow with order bearing and get the bearing puller. Thanks!
Craftsmen trying to say that little motor is 3HP! Its impossible to get that from that motor.
Thanks for posting this bro. I had the same piece of melted plastic blocking my motor from spinning. This video helped me solve the problem.
Outstanding video. Thanks.
I was hoping there was a fuse i could just change or reset, lol. Learned alot here. Great instructional video!
Funny Story-
I had a craftsman table saw for years & years. THEN, one day I was sawing and
a bolt of lightning flashed out of the motor & the breaker popped. After the
smoke cleared, I pulled on the belt to see if the motor would turn-NO. So, I
bought a new motor. While I was removing the old motor I found steel
powder all over it. Sometimes, I put on a metal cutting blade and cut steel.
Apparently, the steel shavings dusted the motor & eventually got into the cooling
holes. SO, I cut a piece of cardboard & mounted it shielding the new motor so
that any shavings will stay out of the new motor.
!
Good video but I wish the audio was clearer. Sounds like a couple guys mumbling to themselves.
This is good info, thanks!
Not sure if you remember but when you took the motor out did you have 2 shims fall out from one of the bolts holding the motor on?
I do not recall that. Send me the time in the video where you see me taking off the bolts and I will check mine to see if I have them.
@fixit9888 no there was no certain time in the video, I ask because when I had to tear down the motor and replace all bearings on my saw a few days ago and when I removed the motor 2 shims fell out from one of the bolts that hold the motor on. Thanks for the reply tho.
One of the best repair videos I have seen. Bro, you have a talent not only to repair, but to provide detailed narration while doing so. Very detailed. Very well done !! One question. What was the plastic blob you removed and did you replace it with a new one ?
The plastic blob was the bearing cup. It melted because of the friction, so it became just a blob of plastic.
@@fixit9888Thanks much for the quick reply ! Thank you for the awesome video too, Bro !
Excellent video and exactly what I needed! I found the same table saw on the side of the road yesterday and your video proved to me that I can bring it back to life. Thanks so much! You're awesome!
@@fixit9888 I just opened mine according to your instructions. I now know what the plastic blob is. It is the casing for the impeller. It is not the cup at the end of the shaft. Just wanted to let you know. So your motor is now missing an impeller cover and therefore the airflow is altered. The cooling can get affected.
@@panthera7291 look online and see if you can buy that casing. I think it's expensive. I have found used parts for other things on eBay. That might be a better route for you if you do not want to spend too much on the repairs. Hopefully you find it there.
That bearing on the end seems to be the one that fails. I got the rebuild kit with 3 bearings and brushes, but just changed the end bearing opposite of the blade because the others seemed OK at the moment. Good info, thanks.
If you would heat the bearing it will expand and might just fall off by itself.
I have never tried that method. If I have any issue with a bearing, I will try it out. Thanks
At 6:12, I found once I loosened the lower 2 bolts, I cranked the height knob all the way down and it gave me more room to get my fingers under to finish unscrewing them.
Excellent repair video. Thanks!
Good job! I just disassembled mine and ordered a rebuild kit. I’ll use some of your tips when I do the rebuild. I especially like the tip about lowering the blade to get better access to the motor mount bolts. Thanks.
Excellent video, thanks for the instructions and parts references. I have the same model table saw with the same issue. Cheers!
No problem, it was a fun fix. I am sure you will get yours back and running too. Good luck with your project
Thank you,nice job
Great job, I just had the back bearing start squealing and then freeze up while cutting some plywood and your video has some great advice on what I needed.
Hi, I am fixing my Craftsman table saw motor just like what you did to yours. I need to get the plastic cap for the ball bearing. Can you tell me where you get your.
The plastic cap is the "bearing cup". I attached a link in the description. Hope this helps.
@@fixit9888
thanks, I will check it out when I get the ball bearing.
By the way, your video is very detail and helpful. Great job!
Received the ball bearing and the bearing cup.Finished repairing the motor and put it all together in about an hour. The table saw is back to service!
Thank you for your video and the bearing cup link.
Where do you get the rubber piece to go around the bearing
Nice video. I'm going to attempt it on mine. Problem is the back of the housing is deformed and I worry the bearing cup will wedge again seizing the bearing once more.
If I was in your position, i would probably try to add something to the bearing cup to keep it in place(some type of adhesive). I wouldn't buy a new housing because it cost too much. The bearing cup is just holding the bearing in place so that it doesn't begin to wobble. If it doesn't work out, is time for a new machine i suppose.
Thank you for making this video and in such great detail. My table saw just quit working, I’d like to give this a try but I have a question.. What kind of adhesive should I use to glue the bearing cup?
Don't put any adhesive. The bearing cup is there to retain the bearing. It will not come out once the bearing is inside the cup.
Oh, really? I purchased a plastic epoxy for the bearing cup. I assumed because the old one was hard to remove it was glued in place from the factory. Im still waiting on the bearing cup to give this a try. Thank you for making your video and for your reply.
Please edit for repetitive explanations.
Exceeds excellent; doubt if a better video on this project could be made. Perfect !
Put the bearing in the oven at 220, put the armature in the freezer.
220 C or F or even K ????????
Nice job, I bet that felt good. And you were obviously confident since you didn't bother testing the motor before you reinstalled it.
Thanks, I had a pretty good feeling that the melted rubber was not going to allow the motor to turn and because of the humming sound coming from the motor.
Well done my friend. I'm going to do the same soon. Thanks for the video!
I know you will be able to get it back and running. Don't hesitate to ask if you have any question. I don't mind helping out
I wanted to ask you, from where did you order the bearings and the end cap?
Hi, thanks for your comments, I ordered everything on Amazon.
What’s the bearing item number if you have it excellent video
This video set me on the path to fixing my table saw. I have the rebuild kit from Amazon. I don’t know if you remember specifically, but can you tell me if the two bearings on the armature need to face in any particular orientation? I’ve looked at them and can’t see any reason why one side needs to face inward or outward. Thanks for any insight you might have.
