Shame that dewalt has cheapened this planer so much. (They did it to every other tool, so I shouldn't be too shocked suppose?)

[@RoCDIY]

DeWalt was the brand I looked forward to getting when I could afford it. Not anymore. I haven't had much luck with any of their tools... table saw, cordless drills, and planer. I think DeWalt designed the planer to crap out when you push it just a little too far. Makes money for them.

[@carterscustomrods]

@RoC DIY well, look at it this way... Their tools, for the most part, are less expensive now than they were pre-covid. Then look at their sales, and their profit margins skyrocketed and they broke new records every month in overall sales. So, they cheapened their product quality, increased gimmicky hype in new releases, and cut costs. It's the same thing I've seen happen back in the day to Stanley with Craftsman, Black & Decker, etc. It sucks, because Dewalt was great for so long. I guess it happens to all tools eventually. Thank goodness for Makita.... for now. Lol

Is it possible to do a 240 V motor?

[@RoCDIY]

You can purchase one that is 220-240V. You more than likely can do a conversion, but it would be expensive and it would be more than just the motor that would need to be converted... motor, switch, circuit breaker and possibly all wiring, unless wiring is rated to handle 220V.

[@rhar641]

Why can't you just buy a replacement motor for DW735 Planer.. Or if you can,, Please tell me where. Rod

[@RoCDIY]

I am guessing you want something you just pull out and drop a new one in. Unfortunately, many people experience motor failure at different levels, so most places are going to sell everything separately. Also, if it's the work you don't want to do to install it, most of the work isn't the motor, it's everything else getting to the motor. Check out toolservicenet.com. You might want to take advantage of DeWalt's rebuild program for $329. It's on the toolservicenet.com website.

[@beaublue5321]

Currently dealing with same issue. I have a type 1 though and parts are 497$!!!! Do you happen to know the difference between the two types?

[@RoCDIY]

Made in Taiwan(type 1) or China (type 12). I don't know if they are still being built in these locations. The type 1 has a more robust/heavier Armature. The Field and Motor Casing are larger. Rollers are different. Someone commented that the belt is different, but it isn't. I verified it. Type 1 is 3lbs heavier than type 12. There are other parts that are different, but I would have to look them all up. Where did you look to purchase your parts? Have you checked toolservicenet.com? If in fact all of your parts will cost $497, then you might want to take advantage of DeWalt's rebuild program for $329. It's on the toolservicenet.com website.

I really hope it helps you out. It has helped others

[@bobbybenedict1027]

I have the same planer I bought in February 24. Ive used it 3 times all together planed 3.5 6ft. Boards and the motor is burning up and popping the breaker. Really appreciate the video! It's going to be a huge help to fix mine! Thank you again!

[@RoCDIY]

I truly hope it helps you out. They aren't cheap and definitely aren't cheap to send in for repair. Good luck!

Epic thanks. Followed along with my replacement armature and I'm now back in the making things flat with sawdust business. You're a legend.

[@clayedwards987]

Sir, i appreciate your videos here. My planer exhibits the same issues but it is a type 1 (Taiwan) rather than Type 12 (China). I see your comments on parts and assume you mean they are different. Can you point to me how to find the correct parts for Type 1?

[@RoCDIY]

Thank you. If you go to the following website: toolservicenet.com. >> Buy Parts (Browse Parts) type in "DW735," click "View Parts and Diagrams." Select Model Type... select "Type 1." On the right hand side will be all the parts available for a type 1 DW735 DeWalt Planer. Let me know if you have any issues.

[@apixdesign5689]

Thank you! Thought I ruined my Dewalt planer and am glad I can fix it relatively cheap and easily because of this video

[@RoCDIY]

Thanks! If it helps you out and saves you money then that's awesome. My mission will be accomplished.

[@sylviaknutcecily]

very helpful! unfortunately parts are now much more expensive. Aug 19, 2023 - field is $65, Armature is $173, cover is $25.

[@RoCDIY]

The part numbers I gave above are for a type 12, DW735 Planer. I believe you looked up the parts for a type 1, DW735 Planer, which are and have always been more expensive.

[@lincolnswaby3102]

i thought the dw735 motor was metal

[@RoCDIY]

There may be a metal motor casing out there, but both of mine are thermoplastic.

[@houleftbll88]

For those who have experienced this issue, such as myself, you just saved us/me hundreds. Many thanks and great job explaining.

@@RoCDIY i got you. As for the bearings and the brushes. i ordered 1 bearing thinking it was a set, got one bearing. Ordered 2 brushes, got 2 brushes. just a comment incase someone is also ordering

[@steveh8724]

FYI, the early units through 2018 at least were Type 1 and were made in Taiwan. Later units are Type 12 and are made in China. There are some reports of better build in Type 1, but info is pretty thin. This might explain why Type 1 specific parts are more expensive, even though they are probably all ‘equivalent’ in terms of nominal specs and dimensions.

[@RoCDIY]

Thanks for commenting. I saw the same info posted on Reddit awhile ago. There seems to be more to it. There is a huge price difference between type 1 and type 12 parts. I also read that there are size differences between the type 1 and type 12, specifically the armature. Type 1 is smaller than type 12.

[@carterscustomrods]

Yeah, the type 1 was great. The motors didn't bog down so bad. Mine was damaged beyond repair in a fire and the type 12 lasted just 800 linear feet of maple before the motor burnt out. The older type 1 I had rarely strained, I ran thousands and thousands of linear feet through it. Dewalt, after having my type 12 go out, Dewalt swapped it out for me, on the 3rd pass of oak, it started to make a grinding noise. Went through it all again. Dewalt eventually got my money back to me 4 months later. It's sad. I used to use 90% Dewalt. Now, I'm down to 10% Dewalt. Stanley Black and Decker have really 💩 the bed with Dewalt since 2019.

Same issue. DW735 arced-out. Burnt up. THANK YOU SO MUCH FOR THIS VIDEO, brother! 🙌🏼 Im gonna order the field, armature, and brushes. I hope they come in one kit like yours.

[@RoCDIY]

No problem. Thanks for watching and commenting. I hope you get it up and running soon. Check and double check everything you do when you put it back together.

[@karlw5730]

Thanks for your video and all the information. How did you get the spade connectors on the brushes? New field has the wires to them, but can't figure out how to get them connected. Thanks.

[@RoCDIY]

No problem. Thanks for commenting. I don't know where you ordered your parts, but when I ordered the field, it came connected inside the motor housing (casing). I didn't have to worry about connecting the spade connectors to the brushes. Did you order your parts from toolservicenet.com? The only way I think you could do it is with a long set of offset needle nose pliers and a small mirror.

[@karlw5730]

@@RoCDIY Thanks for your response. I ordered a new armature, field and bearings. The motor cover was reused. The needle nose pliers and reaching in from the "back" side of the motor house, I was able to manuever the clips onto the connectors to the brushes. A bit of fussing and no cussing LOL

[@RoCDIY]

@@karlw5730 Glad you were able to get it done. I am glad I didn't have to go that route when I rebuilt mine. Hope you get it up and running, if you haven't already.

[@sandorfogassy3007]

Thanks. Not much information available about these repairs.

[@RoCDIY]

No problem. Trying to help out where I can.

[@MadeInDaShade]

Hey Roc Diy, how did you know your motor was done? I currently have mine torn down to the point where I am about to take the motor off and disassemble it, but I'm not sure if it's just the brushes that maybe need to be replaced?

[@RoCDIY]

Did you see my other video? Motor Disassembly and Diagnosis (9:32 in video). Mine went from running to suddenly stopping/circuit tripping. Then it went to just a humming sound, then a puff of smoke came out the back right side which led to me disassembling it. The brushes were the first thing I checked and they didn't look any different than new ones. The serration you see on the brushes is normal. You can definitely get to and check your brushes without disassembling the planer. I knew mine was done once I had it completely disassembled. It was off center with metal to metal contact on the armature & field, and pieces of melted plastic inside.

[@billballeza377]

I’m so glad I watched this because I learned the proper way to install the drive belt. Next time I have to replace one it won’t take me as long and it won’t be as difficult. BTW, spend the money on the OEM belt because the cheaper ones on Amazon break immediately. Thank you!

[@RoCDIY]

Bill, thanks for watching and commenting. The belt would probably be something I wouldn't go cheap on, but OEM is expensive. Really surprised to see how expensive they are.

[@binhnguyen4902]

Hi sir ,How much you spend for the parts and where to buy online? Thanks

My DW735 just broke, looks to be the same problem, motor loss speed and power with burnt smell. So I googled replacement motor and couldn't find one but your video showed up, it appears you have parts list in your description so I'll go through it hoping I can get same parts.... I just got done watching this part 2 video on planer repair, so far you did very good job on showing this on-going repair. Thanks for posting!!!!!!!

@@RoCDIY Well darn it, just as I thought I could order same parts as you did for 735 planer, it appears that the Type number is different, mine is a Type 1. Now I have to try and search out if the parts are different, and that diagram on that web-site isn't easy for me to figure out, numbers and lines going every direction. It would be real nice if I could order the complete motor.......

[@RoCDIY]

@@job38four10 Unfortunately, the parts for a type 1 are more expensive than a type 12. Here are the minimum parts you need for a type 1, DW735 Planer: Diagram #217, Ball Bearing, part #5140011-77, $15.12 (don't order 2. Order 1 to get 2 sets of bearings). Diagram #219, Field, part # 5140011-78, $65.09. Diagram #221, Armature, part #5140011-79, $173.73. Diagram #222, Motor Cover, part # 5140011-81, $33.76. Note: The Field will be installed in the Motor Cover when you receive it. Don't order the Motor Cable (diagram #220) when you order the Field (diagram #219). The Motor Cable is included with the field when you purchase it. Check your brushes to ensure they are not damaged. If you need them- diagram #226, Brush, part # 5140011-85, $8.58.

So do you think 5140011-76 the right # for my planer? I'm really nervous that I might order wrong parts, but right now I'm nervous about a lot of things.

FYI for belt installation remove large pully

Thanks! Good to know. I'll keep it in mind the next time I do this, since I am sure I will.

[@fowlerfinefurniture]

Thank you for your help. My motor was sparking like crazy, I replaced the brushes but it kept sparking. Not sure which parts I really need to replace so I'm doing the armature, bearings, field, and my switch (one of the negative connectors on my switch was totally fried.) I've also had mine less than three years, a little concerning in terms of the quality of the motor. Saw that the bearing comes with two after I already ordered two, guess I'm getting four now haha, the website isn't very descriptive but the prices are good. hopefully I will up and running again soon.

[@RoCDIY]

No problem. Glad I can help out when I can. They got me on the bearings too. I now have an extra set as well. Let me know how everything works out. Also, when you get it up and running, stay away from the thick side. Temptation to remove more will burn the motor up. I am pretty sure that is how mine burned up even though I was within tolerance.

[@fowlerfinefurniture]

@@RoCDIY Also, I am just figuring out that I have a Type 1, which the armature is way more expensive -_-, considering putting in a type 12 if I replace both the field and armature, but also might just be worth it to do it right the first time.

[@RoCDIY]

@@fowlerfinefurniture I had no idea there was that much of a price difference between the two types. I'd call DeWalt to verify whether you can put a type 12 armature & field in a type 1 planer. Whether it is a type 1 or 12 may not have anything to do with the armature & field. Then again, it could have everything to do with it since there is a price difference. The bearings are a different part # and price too.

[@joelmarinho1537]

Here in Brazil I have the same problem, but I solved it by installing a 3HP brushless motor. Take a look at the video on my channel.
