Have you changed out blades on your planer? Changed out to helix cutter? You are a great teacher and your fix the table saw video was a masterpiece. I agree with Matt below, this is the best one I have ever seen.
Thank you for this video. I don’t have a dewalt or a table saw with this issue. However I am one of those “I can do it myself…let me just check UA-cam first”. So I always appreciate whenever people put up clear step by step instructions like you’ve done here. As I stated, I didn’t NEED this information but I watched the entire video and appreciated all you did for those who do need it.
Bro, this was THE best instructional video I think I have ever seen. Your style is flawless. You deliver very detailed information concisely, you are very comfortable on camera, production is perfect, everything is perfect! You should make videos about how to make videos. You should teach PhD film students. I am almost glad my saw broke or I would never have seen this. Do not change a thing man. Thank you so much.
Thanks for the awesome compliment, and good luck fixing your saw!
Just repaired my Dewalt table saw. Excellent instructions. Your are right, it is about a 4 hour job. For me it was harder taking apart than putting back together.. I stripped one of the hex screws that holds the riving blade and had to drill it out. Got the gear case in the mail 3 days after ordering it for $57. Thanks again.
Thank you, I got stuck on where to separate the motor from the gear box, and that's when i found this video. Ty
A BIG thank from my end to putting this video. Your video saved me 600 bucks today. ❤
Taking pictures of wiring is always helpful.
Awesome idea. Thanks for sharing!
Thanks for this video. I had a slightly different issue, but watching this come apart and go back together helped me strategize how to tackle my own issue. Much appreciated!
Thanks so much for putting this video together. My problem was that I could raise the blade, but not lower it. Your video showed enough of the inside guts that I was able to solve my problem without any new parts. Thanks again!
Thank you for this video! I've successfully repaired my saw, and your instructions gave me the confidence to do the job.
Tommy, thanks for this informational video. Several years ago I bought your plans for the work bench and built it to most of your specs including the area for the table saw. I bought the same saw and have been using it since. Thankfully, I haven't had this issue with my saw, but if I do, I now know where to go back to. Thanks!
I'm glad to have your support - thank you!
Nice work Tommy. Glad to see you making videos again
Thanks! More to come!
Great work and glad to see you back in action. Thanks for making a very clear instructional video of what seems to have been a challenging, but satisfying, repair for this table saw. Your strategy for disassembly and reassembly will be helpful for many tools. I formerly owned such a saw, but have since upgraded. However, I will definitely be scouting out the "Poor Man's Flea Markets" in Houston to try to to pick up one from the side of the curb and try my hand at repair for resale.
Thank you and good luck!
Thank you for making this video. You clearly put much time and effort into this video, and I appreciate it very much indeed.

Excellent video! I have the exact same problem with my Dewalt DWE7480 after exactly 5 years of some weekend usage. The blade started getting harder to raise up and down after 3 years. I did some cleaning one to two times on the gears which did some help then a few days ago it simply broke. Your step-by-step illustration with excellent explanation and camera shooting angle helps me greatly to decide if I can do this repair. Sadly, I only find it comfortable doing the repair till the disassembling on the motor housing;(. I have ordered the Skil TS6307-00 table saw to replace this one. This excellent video has got me subscribed.
This is a very helpful and useful tutorial and it is a good guide for any saw repair. Thanks for sharing this great tutorial.
Great video Tommy. I dry-lube mine regularly, I hope I never need to do this! I'm saving the video just in case.
Excellent video, thanks. Exact same problem I have with my Metabo. Got it all apart, just waiting on new parts. Thx again,very helpful.
Thank you so much for this! I just finished. Positive I would not have been able to do it without this tutorial.
Excellent video. When I was looking at this saw and a similar Bosch I was concerned about the quality of the gears and their longevity. I’m glad now that I waited until I found an old Craftsman table saw on FB. Enjoyed the in depth description. We’ll done!
That was an amazing video. great camera angles and narration. it is definitely a design flaw. my saw is up and running again. ty
Wow. This is way more work than I would have expected.
Haha me too 😂
Tommy, more frequent videos please mate ...love the content
You just saved me 400$ ,someone is selling this saw for 200$ just because the blade don't go down
Thanks for that video. I had to do the same thing 2 years ago. This design is a bit flimsy because the problem has come back and it feels like I'll have to change it again soon. I remember I spent a lot of time trying to figure things out.. at least next time I'll have your video as a reference!
Thanks for sharing those tips and the make!
Thank you so much for sharing this video! I have the same problem with mine. Now I feel comfortable moving forward since Dewalt wasn’t very helpful.
I'm glad you found it helpful - good luck with the repair!
Great video! Helped a ton!
Fantastic step by step, man! Thanks a lot! 😃
I hope I never need it... But, if I do, I know where to find! 😊
Stay safe there with your family! 🖖😊
Thanks! 😃
Thank you for this video. Very good instruction in so many ways. Including your approach to disassembly for annual maintenance too. I have both the same saw and planer you show in the video. Have you run across any misalignments with your planer? Mine right out of the box was difficult to raise and lower due to the chain drive not properly aligned to the four posts. I attempted to rectify the problem but can not quite get the cutter head carriage to set square to the bed in addition to remaining stiffness when cranking for height adjust. Again I believe a problem is with the four posts and their relative chain and sprocket mechanism. Can not find any tutorial on the TUBE that addresses this particular DeWalt planer problem. Have you?
Wow, I just want to said this fix is intense and I’m not sure I could do if I needed too. The video was great with all the info one might need if u r confident enough to give it a try. Thank u!
You can do it! One step at a time 🙂
Thanks for sharing, I have this very same saw myself and guess what I'll be doing by way of preventative maintenance this evening! Does seem to be a a major design flaw in what I think is an otherwise very good machine.
That was very educational. I don't need to replace the housing on mine, but I am curious where you got the housing from and how much it cost?
Thanks for this video, where did you buy the replacement part🤔. Lots of details I would of missed.
Wow pretty crazy for relatively new looking saw. Really DeWalt.
Excellent run down cheers
Thanks huge help fixing mine
Nice job Tommy! Thanks for sharing with us!💖👍😎JP
🙂
What an absolutely idiotic design approach! There should have been a separate smaller piece of threaded aluminum to mate with the steel threads. In that event, a much smaller and hopefully cheaper replacement piece could be used. Makes me wonder what other shortcuts Dewalt has made with all of the other machine tools I have purchased from them!
This is one of the finest videos I have seen of its type. The fact that you figured this out yourself is outstanding. If you aren't an engineer by occupation, I'm sure your could have been. Thank you very much.
Did you ever say where you got the replacement gear case/motor mount? Sorry if I missed it. Great video!
Thanks for sharing!
Great video thanks
Impressive that anyone could figure out that extensive of a repair which is well beyond my ability. Think it’s super important to stress: First thoroughly clean/lubricate gears and threaded rod-mine had exact same issue and thankfully that’s all it needed to work better than new.
great video
Thx for the video, repaired my dw745 type4. Part only 40€ and 1.5h work time. Thx!
Had this happen to my Ryobi table saw.
The problem as I see it is the steel rod on the aluminum housing. I was told by a shop teacher years back that steel and aluminum don't work together because of some reaction between the two metals that eats away at the aluminum. If you have aluminum storm doors you'll notice that the steel screws will loosen over time due to this. A brass threaded insert on the housing could probably solve this problem.
Aluminium on its own has inherently superior corrosion resistance to steel. However when they are in contact galvanic action between the aluminum and steel parts can lead to severe corrosion of the aluminium. The corrosion will be more pronounced in damp conditions. I would use a protective grease.
Yeah 👍 was looking for the correct answer, well done. The aluminium body needs that thread boring out and a threaded insert putting in. Why DeWalt didn't design this way amazes me, It would cost a couple of pounds / dollars.
good video, thanks, and thankfully my saw doesn't need this yet, its quite a job.
Life saver right here
Great video, I had this exact problem after 2 1/2 years fortunately De Walt replaced the machine under warranty (in Australia). If it happens again this video is the answer.
Nice that they handled it under warranty.
Interesting Dewalt told me to pound sand when a router died on me 11 days after I bought. I buy Makita now after using Dewalt exclusively my entire life. Hope it was worth it to them.
Great video thanks..I believe you forgot one o ring inside the housing
Great vid
Thanks!
Did you look to see if there is a helicoil to repair the stripped thread?
That was a doozy of a repair. Great tutorial
My 7485 is fairly new. Is there any way I can prevent this from happening to my saw? Maintenance wise? Thanks for your video.
When the saw is dificult to raise or lowering lubricate with wd40 the sliding bars...
My dewalt binds when raising. I’m going to use this video to see what’s going on. Thank you
Excellent video! First of your vids I’ve seen. Don’t have this saw, but still watched it simply for it’s presentation. What I liked...if I had really needed the info...no music! I hate music in informational vids...no excessive commentary, in my opinion...no ‘waving of parts’ in my face for 10 seconds!...excellent close up, well lit camera work! But back to the repair...please blow with air hose and dry lube these aluminum threads ‘regularly’...as ‘they’ say, or this failure will surely reoccur! You should post a video on “how to do videos”.
Thanks for the kind words and excellent suggestions! I usually add music, but specifically left it out of this video because I imagined people watching and rewatching it during a repair…music would definitely be hard to handle on repeat. Thanks again!
@Philip Whichard: What dry lube do you recommend? Starting years ago, I anticipated such a problem and every 3 months or so (or during every "undercarriage cleaning", I spray graphite door lock spray. It does attract sawdust like lithium or grease based lubes. I live in a very humid and salt air environment and have to keep those rods lubed also to prevent rust, which prevents binding. Thanks in advance. PS - I really liked this video for the very same reasons you cited!
I’ve owned my Dewalt for less than a year now and I love it. I saved your video just in case, but do you have any suggestions for preventing this problem or is it just inevitable?
1. Hook up a shop vac and use it !!
2. Blow out the dust around the motor, threaded riser rod, and the guide rods on either side of the motor. The more often you do this the better.
3. Use a silicone dry spray on the threaded riser rod a guide rods regularly.... I wish I had !!
Repair complete and astonishingly I have 2 leftover hex screws. Help!
Hmmm…that’s not good 😂 Have you watched the video again to see if you can spot where they go?
Thanks a lot this will help a lot of people, but remember this is no diu project. Any chance doing a video of a not removable blade in a DeWalt jigsaw? Call it stupid but I have now 4 with a stuck blade. Thanks for sharing.
I’d love to tackle this project! Send me an email through the website, and let’s talk about it.
Seems like a good application for a heli-coil or similar.
Yeah, good idea. I wonder about drilling out that hole in a straight enough fashion. Might have to build a jig to hold it in the drill press. Thanks for sharing that idea!
Everyone should save this video to share it or use it when the time comes. Thanks!
Thanks!
Greetings, do you use your saw to make half lap joints? I have a new (warranty replacement, i tried to address this issue one with the DeWalt service center ) DeWalt DWE7485 table saw. My saw will only maintain its dialed in height if the wheel is at the top dead center or bottem center. E.G. when I start the saw with the wheel at the 9 o'clock position it will slowly rotate counter clockwise to the 6 o'clock position. My assumption is that this being a "contractor" saw it was only engineered for rip and crosscuts. It doesn't matter if the blade is say an extra 1/8 of an inch too high. It was not engineered for jointer precisition. As you know the raising and lowering mechnanism doesn't have an adjustment to "stiffen" the action. Is it because my blade is a 7 1/4 inches and yours looks like a 10 inch? Maybe it's an inertia issue? Any guidance you can provide would be greatly appreciated. Great video by the way!
I have never been able to get my blade to hold precision on height, so I think you're right in that it's just a limitation of the saw. They never intended these says for precision work.
Sounds like the adjustment wheel rotates to the bottom due to the vibration.
Would a weight like small vice grips clipped to the bottom of the wheel stop the problem?
@@douglascolman4501 I use a spring clamp on the wheel, resting against the lock lever. I think your solution would also work.
@@OneMinuteWorkbench Thank you for your input. It's greatly appreciated. It's been my experience that if you go with anything that's a bit out of the norm it's really hard to get any guidance or information
Their other models have a bolt that can be tightened. For the ones that don't people add some weights to the crank.
Damn this is pretty involved, hopefully my saw does not need to be disassembled that much any time soon :p I try to remove it from my bench and clean it up/lube (dry PTFE lube) all the gear and moving parts at least once a year. I should probably do it soon.
They say maintenance is easier than repair...I probably should've cleaned mine more 😂
@@OneMinuteWorkbench Honestly I'm not sure it would have helped, steel threaded rod going into aluminium threads ... one is just harder than the other. Maybe cleaning the rod could have helped but it's not like you use the saw on a job site, I think the threads just wore out with time.
For sure. It was eventually going to wear out...it just would have been nice if they would have made the threads part of an insert so the repair could be easier and cheaper. I guess they figure most people will just buy a new saw.
Mine just started rattling and skipping. I remembered seeing another video on this flaw a few years. I am considering alternative repair options. Do you happen know:
1) What type/size of thread is the threaded rod?
2) Is there any excess thread on the rod when the blade is fully lowered or raised? In that case, one might simply glue a nut to the aluminum casing on either side of the internal thread.
(I would check myself, but my saw is at my project site, and I'd like to come prepared next time there)
Just rethread the housing. If it’s really bad, drill out the threads and tap in an insert. Run the threaded rod through a die with the correct pitch and thread count for good measure.
@@tombacher8517 I don't have any of the necessary tools for that (yet). Do you happen to know what type of thread is used?
How old is this table saw? Seems too new to need such a major part replacement. Great video though. Thanks for sharing. :-)
It's made out of plastic. He should get a classic Craftsman, Delta, or Rockwell table saw from the 70' to restore.
Good job I don't think I want to go through all that to save my saw
I have the same saw and it’s developing the same problem. I’m not sure I want to take on that extensive repair, specially taking the motor apart. It’s disappointing that a brand like DeWalt chose such a poor design: even if replaced the aluminium housing is bound to fail again.
👍👍👍
Thank you. I have the same problem to fix. Bad engineering from Dewalt.
Wouldn't hurt to put a dab of anti-sieze on steel threads that die into aluminum castings for future disassembly
Great suggestion!
Struggling find this part
What is the name and part number of it please ?
I forgot to add the link to the description - here it is: www.ereplacementparts.com/gear-case-p-547025.html I hope this helps!
So basically, you created the video manual that didn't exist. Maybe DeWalt should credit you for it and send you a gift :-)
Wouldn't that be nice 😂
@@OneMinuteWorkbench Deserved, I guess :-)
They likely view it as lost saw sales.
Hope myin never breaks looks like a rite pain in the hole bud
yes i have seen this problem in the uk........series 4 table saw lucky for me i have had not had this problem i use compressed air to clean the shaft and lube it with light oil not grease otherwise sawdust sticks to it, bad design from a big brand company come on dewalt offer a call back warranty
😃
yo this is hard lol
I always help the mechanism a little bit by holding the blade slightly while dropping it, and gently lifting it while I crank to raise it. If it makes grinding noises, clean it and use a dry lubricant.
Don't throw that housing out. Keep it. Next time that thread strips your better off putting a helicoil in. Ally wears and strips in no time
OMG just when i think i have made up my mind on which saw to buy i see something like this. Dewalt, Skillsaw, Ridgid, Hitachi. Tired of watching videos. So.....how long do we think it will take these companies to correct this proverbial design flaw, as if hasn't been around for a while.
Yikes.
🤣
