Fantastic video. I will pre-order the bearings and get this done on my DW712! Thank you for putting the time and energy into this video for all of us, much appreciated!
Thank you so much. I followed you instructions and my saw works great now. I had never done a repair like this before and it was so helpful to see it done properly and explained. Excellent video!
Saved me some money, thank you,,I passed on replacing the bearing and just put a new armature in for 85.00. Your video was perfect, took all the questions out.
Great video. Clear, concise and easy to follow. It has just saved me a small fortune in repairs and time locally (NZ). I was able to repair my Dewalt in a couple of hours at a cost $9.90c. Did heaps for my confidence too! Thank you very much :-)
Very well done!! And that fan end bearing is exactly what has failed on mine.... Your tutorial was just enough detail for this old guy to get the job done as soon as my bearing gets here... Thanks again for your informative details...
Thanks for sharing! After 10+ years, my saw is finally ready for new bearings. Seems like they didn’t over tension the belt at the factory on my saw. The replacement looks pretty straightforward. I’m going for it. Wish me luck! 🍀 Cheers! 🍻👍🏻😊
Super cool I have the same saw, have already stripped it down and my bearings are in the exacted same condition as the one in your video. Very helpful 👍
Excellent Video. Very nicely explained. Professionally done. In India, we get a different kind of bearing pulling tool. It is a kind of tripod with a bolt in the centre. The tripod clamps the bearing and when the bolt is tightened, the bearing pops out.
Thanks very much. Probably best tutorial I have found on this subject. So that is a good reason to follow you! Thanks again for all the time and knowledge you have shared.
perfect. I am a better carpenter than a mechanic but I will fly through this repair after watching your vid. Thanks so much. I live in a rural area of Alberta and not in the big cities too often to have repairs done.
best bearing replacement tutorial I've seen so far. I especially liked the comment that dewalt put way to much tension on the belt because I take good care of my saw and have never had a bearing go out on a saw so quickly as my dewalt 780, just 13 months of normal use. Thankyou! 38 years of being a professional trim carpenter I have to say that the Dewalt 780 is the finest miter saw I have ever used ,just wish they had put better bearings in it. And hopefully this repair will be covered under under my warranty because of the tension issue you pointed out. I have miter saws 30 years old that the bearings have not been replaced and still run fine.
I really liked the 708, I think its the King of the Miter saws. You can start on the edge of the board instead of into the board with the 780. Of course the 780 is a bit more compact. I'm planning on buying a 708 that needs bearings and putting some good Nachi sealed Japanese bearings in it. OEM: Dewalt DW718 / DWS780 / DW708 Miter Saw Replacement Ball Bearing (2 Pack) # N127530-2pk Here's the size I found: 6302-2NSE Nachi Bearing 15 x 42 x 13 MM
Sorry to be off topic but does anyone know a way to get back into an instagram account? I was dumb lost the password. I love any tricks you can give me
@Raphael Aryan Thanks for your reply. I found the site through google and im waiting for the hacking stuff now. I see it takes quite some time so I will reply here later with my results.
Thank you for the video. I repaired my saw although I have an older model so the process was slightly different. Nonetheless I couldn't have done it with out your instructions. Thank you again.
I used this to repair my DW718. I thought it was ruined forever and a simple bearing replacement like you show here did the trick. With a bearing puller I removed the race as you showed, however, I didn't have an arbor press quite big enough to press the new bearing on. Here's what I did: I drilled a 9/16 hole with a paddle it in a 2x4 and placed it in a vice. I put the armature in the freezer for 4 hours. I placed the new bearing in the oven at 350F for 20 minutes. It slid on with literally no resistance when I tapped the bearing onto the shaft while using the 2x4 as a precision guide to align the bearing with the shaft.
Wow, awesome video. I just had the bearing go on my DW718. Belt was ridiculously tight. I wish I had been diligent enough to check the tightness of the belt. Bearing was making a noise for awhile. I wrote it off as bad brushes which I changed. I was in the middle of a job and bearing went before I finished. Thanks for the step by step process.
Thank you so much I have to go pick up the parts this week and do it on my job so that was very informative. And I like to detail that was given thank you.
Great informative video. I would recommend cleaning the commutator bar with fine scotch brite whilst the armature is out, especially if there are signs of discoloration (dark areas).
Thank you so much I’m a subscriber now. I have many DEWALT tools never knew the belt was too tight from the factory. I always try and take the best care of my tools did I know the belt was too tight I would have adjusted it when I got it. Hopefully it’s not to late now I know thanks for the post
Ours sounded like death. Boss said throw it away. So i kindly obliged... ;) thanks for the video and the TSB at the end. I feel like bearings, belts and a bearing vice should be in every trailer. It can shut a site down for the day.
Good video. Very informative and practical for a DIYer with simple (and accessible) tools. If the large bearing is only partially failed, you may need to pull all of the plastic (or metal) spacer bits out with a needle nose and push all of the ball bearings to one side before breaking the outer race in your vice. If the balls are evenly distributed within the race you won’t be able to break the race and you’ll probably damage your vice before the hardened steel of the bearing breaks.
I am humbled. And annoyed. And I feel really really dumb. My 780 suddenly made noise and the blade wouldn't spin and it sounded horrible when I turned it. I went to youtube and found this, and it sure sounded like my problem. So I found a bearing in town and got the armature out and both bearings were perfect. So were the brushes. But the blade still sounded bad and wouldn't spin even after the belt was off. So I checked it to see what I'd need to pull the blade. And that's how I found the thin little slice of four by four that had gotten sucked up into the blade and was caught between the blade and the housing. Way up there where it was hard to see. So I put it all back together and everything's fine now. Except I lost about half a day. And if that bearing ever does go, I'm ready now! Great video Jamie. Oh, and the belt tension did feel like it was kind of high so I'm probably better off now. :-)
Cool video. I have the 718 type 2. The base is cracked. Can you do a video on the proper procedure to change out the base and reset & realign/square the saw> I might be over complicating it but would be helpful.
Very helpful tutorial. I just got a used 705 saw. The seller said the blade brake didn’t work anymore. Can you refer me to a UA-cam or link to information as to how to fix this problem? Thank you Gary
hi this is jose gonzalez i like the way you explane step by step do you know if the replace of the bearings on my dewalt tile wetsaw is the same proces
Used a butane torch to warm the pulley and it slid right off. Never did I imagine it be that easy. My cheap vise won’t crack the outer race; moving towards heat and beat or cut.
Jamie, my DW 708 type 4 saw is vibrating from the bearing that the blade rides On....do you have a video that covers the replacement of that bearing?....great professional video....the only question I have as a first time viewer and future repair guy is you did not cover the part no. of the bearing, etc. Thanks a bunch!
My DWS779 is fairly new and I haven’t used it yet since I got it about two months ago, should I check the belt tension and adjust it if needed to help the longevity of the bearings?
Thank you for the great step by step instructions. The vise cracking is much faster than cutting with a small metal cutoff wheel.
I just replaced my bearing and I couldn't have done it without this video. Straight and to the point. Awesome content. Thank you for posting!

Just finished bearing replacement. without this video I would have been lost. Great video + very clear instructions. Thank you very much 👍
Very well done!! And that fan end bearing is exactly what has failed on mine.... Your tutorial was just enough detail for this old guy to get the job done as soon as my bearing gets here... Thanks again for your informative details...
This is going to save me lots of time and money - if I can find a bearing clamp and press. Very good video, easy to follow the instructions. Thanks!
Thanks for sharing! After 10+ years, my saw is finally ready for new bearings. Seems like they didn’t over tension the belt at the factory on my saw. The replacement looks pretty straightforward. I’m going for it. Wish me luck! 🍀 Cheers! 🍻👍🏻😊
Just replaced my bearing and brushes today. Thanks very much for the great instructional video. It was perfectly clear.
Excellent video. You're a good teacher and obviously know what you're doing. Thanks!
7 years later this helping me out . Thanks !
Super cool
I have the same saw, have already stripped it down and my bearings are in the exacted same condition as the one in your video. Very helpful 👍
Thanks. Now all I have to do is find the correct bearings.
Thanks again good video

You made that look easy, now I can get my saw up and running again, thank you!
Thanks very much. Probably best tutorial I have found on this subject. So that is a good reason to follow you! Thanks again for all the time and knowledge you have shared.

I'm sure dewalt did it by accident and not so you have to buy a new saw every year

Thank you. That really helps. Time for an update, though, as some things have changed on the newer units.
Great Video, I couldn't have done it without this video, thanks for putting the time and energy into this video for all of us, thankyou very much.
Very helpful! You did an excellent job of explaining and simplifying the process
very good display ,was able to replace my bearings easily,thank you
great job jamie,repaired a saw for a friend of mine, worked great.
Novice great video . shows logical steps start to finish
This is a great job you did to replace the bearing!
Thank You!

Followed it step by step. Piece of cake. Thanks so much!
This is exactly what I need. Now all I need is a good press and vice... THANKS!
Helped me figure out how to tighten the belt, thanks!
great demonstration
You removing the pulley with a rag and your hand really made me LOL!
Great tip will adjust my belt tomorrow thanks for posting

Great video just what I needed
Great video, very helpful easy to understand and logical, thank you
Thank you for the video it was very helpful. I did my neighbors dewalt miter saw with my vice a hammer, punch, block of wood and a socket.
Very clear video. Many thanks.
Thanks worked great on my friends saw
James did an awesome job showing us step by on how to replace a bearing. Simply and easy to follow!!! Do you have videos on senco hand tools as well?
Great video. The only questions I have that you may have needed to add is how to know when the bearing is properly seated at each end.
What an informative and helpful video, cheers.
Awesome tutorial!! Thank you very much!
Thank you very much for the lesson it will help me a lot
Great informative video. I would recommend cleaning the commutator bar with fine scotch brite whilst the armature is out, especially if there are signs of discoloration (dark areas).
Hi! Thank you for letting us know. That is great information to include!
Awesome job and instructions. Thanks guys.
Thanks Chuck! Best holiday wishes to you. George Merrill

st7650 Do you have any idea why he replaced both of the bearing? The big and small.
Ours sounded like death. Boss said throw it away. So i kindly obliged... ;) thanks for the video and the TSB at the end. I feel like bearings, belts and a bearing vice should be in every trailer. It can shut a site down for the day.
great video just the fix I need. thanks
Clear and educational video.
Great video! 👍🏼 well explained.
Great informative video.

If the balls are evenly distributed within the race you won’t be able to break the race and you’ll probably damage your vice before the hardened steel of the bearing breaks.
Just seeing this. As the person appearing in this video, I can assure you, the bearing WILL break even if brand new. Without fail.
Great vid, can you tell show how to replace the bearings/seals on the sliding shaft of a compound mitre saw please.
Awesome informative video.
good job ..great video
Excellent demo I have to change my bearing, now I know how. I don't have a bearing puller or press

Great job thank you do you have a video of the blade bearing replace ? My Dewalt head is real bad

Cool video. I have the 718 type 2. The base is cracked. Can you do a video on the proper procedure to change out the base and reset & realign/square the saw> I might be over complicating it but would be helpful.
Thanks for the tip
Great video, my problem is the blade bearing. Do you have a video that shows how to replace that?
..very helpful, thank you
Very helpful tutorial. I just got a used 705 saw. The seller said the blade brake didn’t work anymore. Can you refer me to a UA-cam or link to information as to how to fix this problem? Thank you

thank you!
Will this work for a old school single bevel miter saw im not sure the model number but I can get it if needed. Awesome video very nice 👌
now i know what I can and can't hit....thanks for your help
My DWS779 is fairly new and I haven’t used it yet since I got it about two months ago, should I check the belt tension and adjust it if needed to help the longevity of the bearings?
I have a question if the aluminum peice on the armature goes on hard can it be heated (like it was when it was removed) to be put back on
