Question about Dewalt DW744S 10" Portable Table Saw with Stand
You need to check and see if it is the field or the armature that needs to be replaced. if you can use a volt ohm meter you can check these two items. you would use the ohm or continuity part of the meter. for the field, there is a wire coming fromthe elect source and the a spring around the brush holder. the are two of these field coils. if you take one leed to each end and the wire is ok the needle will move or you will see areading ont he digital readout. if you do not get a reading, there is a break in the wire and the field is bad. on the armature, using the same set up on the meter, hold one probe on the commutator. the commutator is at the end and is made up of copper rectangles. put one leed on one rectangle and then use the other leed to touch all the others one at a time. if you do not get a reading on one of the rectangles that means a wire is broke in the armature. if they both showgood, you have another problem. which would be your switch or cord.

I don't know about Cleveland, but a while ago I replaced the bearing on my Sears Craftsman saw, and it wasn't a hard fix. I would expect any competent repair shop could do the repair easily. If you can get the arbor off and take it to the shop, that would be ideal. It only takes loosening a few bolts to get it off. I first removed the cast iron top from the sheet metal base so I could turn it over, but it can be done from the bottom, too. Just be prepared to eat some sawdust. The most specialized thing the shop would need is a bearing press to get the bearing in and out of its seat, and many shops would have these; they aren't very expensive. Maybe a good machine shop which does small jobs could do it for a small fee. A good place to find these is at your local auto parts store, such as NAPA or O'Riellys (here in MIssouri, anyway, but you get the idea). Your auto repair shop probably knows one or two they use for 'turning' brake drums, etc. BTY, I didn't have a bearing press and I did the job with carefully tapping the bearing back on with a sleeve made from a piece of scrap pipe. Tauton Press makes a great DVD on tuning up your saw after this fix, as you want to make sure
it is square with the table in two dimensions - parallel to the miter saw slots and perpendicular to the top. Good luck.

You can try Sears but they can be a bit pricey. I use to send out motors for a factory I worked in to a rebuilder who would even do new windings. Check in your area for a rebuilder, As for the replacement being a Sears unit they may have a similar motor in stock. Good luck.
