They may be burnt and jammed - carefully break them into pieces with a screwdriver (being careful not to damage the brass brush tubes or the copper armature at the end) using compressed air, blow the pieces out and clean the tubes.
Use a flashlight to look down the tubes and inspect the armature as well - if the brushes are burnt into the tubes there may also be damage to the armature.

SOURCE: Bosch 4000 table saw won't work

OK sounds like you are handy. You have electric to the brush tubes? (first unplug saw to test) If yes then I would remove the brushes to see if they were making contact with the commutator. Does the blade spin freely? If not you might have a bearing problem. I would again use air after removing the brushes and then reinsert making sure they seat on the armature. If still nothing then if you are comfortable I would pull the motor housing. But before pulling go to Bosch Tools website and downloading a breakdown of your saw. Let me know if I can help

Ok, the motor turns, but throws sparks on the brushes. This is normal to an extent for universal motors used on that type of equipment.

Try reassembling the saw, and put a blade on it, then try it. If it runs, try cutting a piece of scrap 1x, both crosscut & rip. If the motor can't hold the load, you may still have to replace it.

SOURCE: New or used motor for a Craftsman 10" table saw

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.

SOURCE: Bosch 4000 table saw disassembly

turn the motor housing slightly until you can put a screwdriver between the housing and diaphragm, pull on the one side and push with the driver and it will come apart, I just did one yesterday. To get the armature out of the fan bearing you will need a dead blow hammer to tap on the diaphragm while pulling on the armature. The bearing is held in place with 2 screws, hope this helps.

My delta table saw keeps blowing the circuit breaker on the saw. It does not sound quiet and smooth like usual. I got a good blade its on tight what could this be?


a bad centrifugal starter or inside capacitor and or the electric field if an old type with induction motor , but if it has carbon brushes in the motor instead of an induction motor the commutator on the armature short brushes or a bad bearing(s) on the motor or other gearbearings on the saw drive are worn , it must have a smooth turn if turn on the armature if remove the field /motor house.. look in the motor if running at the end if the carbon brushes you see are make to much sparks a worn bearing without the balls or bad armature collectors or electric field . watch if the bearing is worn by blue hot it can have melting the seat in the motor house replace it all.

I want to remove my table saw motor bosch 4000


Remove the end cap on the motor and remove the 2 carbon brushes. There are 4 screws that hold the motor to the frame and the field and motor housing will pull straight off. The armature will also pull straight out but will require some persuasion and finesse so you don't damage the fan blade.
The most common issue with these is the end armature bearing and with a bearing puller you can perform this with the armature still on the saw. If the bearing is frozen be sure to also check the rubber boot that goes over the bearing and also the motor housing where the bearing sits because it often melts from the friction.

Bosch 4000 table saw tripped breaker. Went to turn saw back on and no power. I replaced the speed control board and still no power? I checked the switch and is fine. Any ideas?


Remove the cap on the end of the motor and remove the 2 carbon brushes. (Ensure the brushes move freely in the tubes and contact the armature)
Remove the 4 screws holding the motor housing to the frame and pull it straight off. Check the copper commutator on the armature and make sure it is not burnt.

22123698-wvjv2ek3boqiwefmtj30yfqx-1-0.jpg If armature and brushes look fine my guess is you have a bad field (very common problem in this tool) #1619PA5590

Motor grinding and sparks


Sounds like you have a bad rear armature bearing.
Remove the end cap on the motor and the 2 carbon brushes.
Remove the 4 screws that hold the motor housing to the frame and pull it straight off.
Most often the bearing heats up enough to ruin the rubber boot that sits over the bearing as well as the motor housing itself. Check to ensure the armature is not burnt

22119051-wvjv2ek3boqiwefmtj30yfqx-1-0.jpg If the armature is OK and it is just a bearing you can replace it in place with a standard bearing puller

22119051-wvjv2ek3boqiwefmtj30yfqx-1-1.jpg Make sure to replace the brushes as well when you do this repair.

Hi, try and change the Carbon Brushes , these are located either side of the motor, you will see a black plastic nut or screw, remove this and you will see a wire inside a spring this will push it's self out and then you can gently pull the Carbon brush out this is about 1/4--1/2 " long ...! if not then replace with new.

not if you are mechanically inclined and have a bearing puller. first unplug the tool and lay it on its backside to expose the motor, remove the brushes and the 4 screws that hold the motor housing to the diaphragm, remove the armature and then remove the bearings, press the new ones on, and reassemble, I would also replace the brushes unless they look really good.

Bosch 4000 tablesaw won't start. Brushes replaced


I found that the remaining problem was a intermittent at the switch, which disassembly and cleaning resolved.
Tilting the motor / blade assembly down allows access from below, to the 3 screws fastening the controller circuit board cover on the brush end of the motor. From there, one can easily test exposed wires for power supply, see that brushes are contacting and clean accumulated sawdust.

The saw has stopped I know the circut it is plugged into is live is there a reset button or built in breaker located on the saw? Dw744 10 inch table saw


NO reset or circuit. You can try and unplug tool and blowing into all the exposed areas of the bottom of the saw. WEAR safety goggles. Then what I would do is check the brushes and if you have a volt ohms meter check the continuity to the brush tubes. Start at the cord looking for a break in wiring and go from there. Let me know if you need more help, but I am going to thing brushes or switch
