How to Modify DeWalt DW745 and DWE7480 to use with 13/16" Dado Blades 

Excellent work figuring this out! This has been a question among us Dewalt jobsite saw users for years. And thanks for the detailed video, including PN's and instructions. Awesome work. Thank you, thank you!

I dont have a saw or do wood work but i still watched this video because it was so well made and explained lol. Good job sir.

Great info. PSA: Don't attempt with a DWE7485. I was really hoping for this to work but Dewalt changed the spindle length, among other things, for that model. They REALLY don't want you to modify that saw..

You do have to spend some time setting the saw up... blade, fence, etc. But once done, the saw is great. Fairly compact which is Nice ru-vid.comUgkxXh-4_3-ZT1fFWP91ZV7iVqzElr0lEb-a I did get an Incra Miter Gauge which takes some setup as well. The stock miter gauge can be adjusted in the miter slot with a little painter's tape... this tightens up the side to side play a lot.

Great instructional video. Thank you for the hard work you put into making this.

Thanks to your video i was able to successfully convert my saw! Thank you 🙏🏾

Thank you for posting I need to do this upgrade.

Very well explained! I will probably never do this modification but still watched the full video - I learned a lot about how to handle bearings and also how to make a simple gasket :) very well done, really!

Quality video. I had the same thought. I'm glad you saved me time by documenting it. Thank you

Excellent video, good job in your takes and editing.

Awesome video! Thank you for doing and sharing the research on this, and for the extremely thorough and clear video.

Thanks man, u deserve more attention for this hard work, and i am sure ur channel will get millions of subscribers. keep the great work up !

Thanks for doing this experiment for me.

Very nicely done!

A great instructional video, I'll do that instantly

Awesome ingenuity! Re-engineering, Great Fix, especially since it should be able to run dado blades from the factory 👏🏻👏🏻👏🏻 Proceed at your own risk of course as you stated

I like so much this video, i want to make this in my DW745, is awesome!

Great detailed explanation thx

Well done! Thank you so much!

Very good info video, same table saw I have, thanks for sharing........

Amazing well done.

Great video you've just earned a new subscriber 👍👍👍

This is great, thank you for sharing!

In european market they changed part numers arbor is the same 5140134-94 lock nut is 1004695-84 ( it was 5140131-58) bearing is 1004695-91 ( it was 5140117-79) hope I helped

Outstanding!!! I bought this saw without a thought of it not having an arbor long enough for a dado stack and didn’t learn that until later. This is an excellent modification!! Using a six inch stack should never overwhelm the motor. Just ordered the parts!!

OK after watching this 100 times, I ordered all the parts and just completed the install on my DWE7480 (USA model). Everything went exactly as you described, and I just cut my first 3/4" dado using the DeWalt 7670 8" dado stack. I went straight for the worst case load to see if the motor could handle it, and it passed with flying colors. A 3/8" deep dado (3/4" wide) came out perfectly flat, with super tiny witness lines that can only be faintly seen at the perfect angle. The motor definitely slowed slightly but the hardwood passed through easily (ran about 3 feet through). The only issue I've had is that when the saw is slowing to a stop, there's a weird noise I hear that wasn't there with the original kit. Doesn't sound like a bearing is failing, and there's no smoke or smell. Just this weird clunkety sound, and it's consistent - only on power down. Overall though, I'm stoked to have dado capability on this saw. Thanks for the great video! Oh one more thing - that 3/8" tubing trick you used - uh, I gave up. I bought 3/8" aluminum standoffs (Amazon), and simply added aluminum tape to close the gap around the perimeter. I put some blue tape on the inside of the aluminum tape so that dust inside the shroud wouldn't get all stuck to the exposed aluminum glue-side. Easy peasy and looks nice. Not as convenient to take apart, but I thought about it - in 5 years I have taken that shroud off exactly 1 time - and it was for this project! So I'm not worried about reusability in this case. Thanks again, fantastic upgrade!

Excellent hack.

Congratulations on the undertaking. Would you know if this modification can be done on the DW-7492? I was very interested and would like to do mine. thanks for sharing your knowledge.

Top demais, parabéns pelo vídeo se eu conseguir essas peças no Brasil vou fazer na minha dw 745

Great video. But that takes a lot for 5/8 gain. I have the same saw and an older model, what I usually do is, pop 2 or 3 piece of dado and naked it work. But I than I just bought the 32.5" now I can use a full 7/8 dado in it. I used to built cabinets for leaving with large deltas saws now I just do small remodeling.

I stack 2 standard blades and 1 thin kerf blade giving me a 7 mm kerf . DW 745 cutting dados @ SION HUGHES channel. Only requires 2 blade washers . Well worth a watch .

Просто красава! Очень круто допетрил и сделал! И объяснил хорошо. Спасибо!

great job detailed explanation.. on the project lit for projects..have your part numbers thank you

any links to buy the parts ? nice work !

nice

Thanks for a great video and all the information you provide. I just ordered the parts to modify my DW745. Question: can you still set your standard blade for a bevel cut of 45 degrees? I ask because of the 1/4" added to the dust collection enclosure might be blocked by the fence gear rod.

G'day, Trick, may i ask where you found the parts list and diagram for your machine? O have a DWT7492B and would like to do the same, but I need to check the parts numbers.

Hi. It has been three years since you posted this video. Is your Dewalt table saw still working well since changing the parts? Thank you

I will bring the insert over to the bandsaw jigsaw and try to cut the rest of the insert out. That way you can use the full blade.

Trying but can't get gear off. What is that tool you are using? Need help...

You have a diagram of a modification for the blade cover that is different than the gasket you made. Was there a problem with the tube gasket? Any updates on how the saw is performing? Thanks for putting the effort into this...it’s a huge issue for many with this saw.!

Hi could you please let me know the bearings number thanks for both is it the same number or different

Can you use any dado stack sets with this method I have the 745 and just ordered all the parts nice video thanks for the heads up

i still don't know how the usa won the cold war. this kind of ingenuity is very russian and very genius. thanks.

Hello , is possible to modify on DWE7485? Thanks

I have a DWE7491RS that needed the gear case replaced. I used this video to partially get me the way, but unfortunately, the motor has to be pulled and my god who has the tools for that kind of thing??? Thanks anyways, I needed to get at least this far to be sure and now my saw is free to a good home!

Very impressive. Why do you need to change the bearings as well. Are they perhaps stronger than the original ones? Thanks for short response.

I would actually think the Dewalt motor should be able to handle this being 2HP, that is a beefy saw for how small/inexpensive these really are.

Nice, but to much work for me. They have a contractor saw that will take a dado blade. Don't know the number.

hi, is it possible to install it on the DWE7492 please?

Hi there, has any one tried changing the arbor on the Dewalt 7485 saw, and do the parts in the video work for changing this model. Thanks all

The DW745 is no longer available to buy new, I'm looking at buying the DWE7492 would this mod work on that also?

Has anyone done this with a 745 ,I’d like to no how it came out far as the motor holding up and not bogging down,there’s a lot of difference in the RPMs between these two saws.

Is this upgrade availible for the DWE7485 ?

“Watch this video at your own risk,” the man said. LOLOLOL. Oh, ok.

That's weird you have to modify it at all I have a Ridgid that will fit my dado set. I don't remember having a problem with my old DeWalt portable saw either. It was 20+ years old and I'm sure larger then the real compact ones. But I don't see why they would short you on spindle length to where you can get a full dado stack on them.

This is for the 10” sAw or the 8.25” saw?

I'm could you please send me the website that you brought this the nut and Arbor please

Video is outstanding but not the music

Русский акцент всегда узнаешь.))

Is it safe to use the blades without washer for wider dados

Just bought all the parts but they ended up being usd....for anyone thats curious

I would have just made an adapter that extends further. Drill and tap the inside and tap the outside for a new locking nut…

What. The number of part?

This guy has a strong Russian accent. Я только услышал первые три слова и понял откуда ты. Хоть ты и в Канаде, но ты не канадец. Я сам в Миссиссаге 22 года прожил, но акцент остался. Рэднэковская музычка немного напрягает. Можно было чуть потише сделать. My humble opinion of course.

Unfortunately instantly voids your warrantee.

not worth my time. better off to sell one dewalt and get another.
