The bearing went bad on the motor. I already purchased the replacement, but I have had a heck of a time finding someone with a bearing puller. I am at the mercy of having to purchase one. Can you recommend a puller that will do the job and if need be, future jobs too! Thank you. Philip

Question: Bosch 4000 Tablesaw Repair Instr...
Model # 0601476139
Trying to figure out the sequence and procedure on how to remove the motor from the saw. Is there a repair manual on the web somewhere or can someone send me one.
I have the saw upside down on an assembly bench. I removed the dust cover and exposed the gear side. Can the motor be removed as a whole unit at this point. I need to replace the bearings.
Unfortunately the motor does not come out as a complete assembly. You will want to remove the brushes. Then remove the item number 111, 4 screws, At that point the motor housing and field should come out. Next to make it easier to remove the armature, raise it up towards you. You are going to have to remove the item number 29 Bearing bracket, it also holds the armature in the Gear Housing. To remove the Bearing Bracket, remove the screws item number 32. You should be able to pull the armature out now.
Got the field off the armature and found ball bearing 13 in bad shape. I didn't remove the armature yet but would it be possible to remove the bearing with a puller and replacing it by tapping it on. I assume I have to remove the locking lever to get access to the screws (#32).
WJA, I found screws (#32) above the lever covered by sawdust.
I removed the screws and the armature came right out. I only had to replace bearing (#13).
I took some longer screws and made guide pins and screwed into Bearing Bracket (#29) and installed the armature back into Gear Housing (#31). I might need longer guide pins so I can pull the bracket closer to the housing.
Is there a trick in attaching screws (#32) into the Bearing Bracket (#31)?
how to fix stripped gear
I'm not sure what you mean by "fix stripped gears"can you give me a little more information?
if you don't clean and lube the tracking glide rods that the motor rides up and down on the new gears will ware out too. blow off motor and under carriage of saw clean rods with mineral spirits and spray with a dry lube that has teflon in it work the motor up and while spraying rods
Question: Motor Housing
Received my motor housing OK, but when I went to install it it does not fit! It seems that the new housing requires a different size bearing. If that's the case then how do I go about getting the correct bearing?
The only thing that comes to mind. Is that you may have not inserted the 2610996948 Rubber Ring into the housing or on the bearing before assembling the motor. If the bearing is loose in the housing, I would think that should take care of it. If it is too tight. I'll have to do some more thinking on that one. I haven't seen a different motor housing used in these saws. Let us know if it is loose or too tight.
Hi, It is way to loose. I'll measure it tomorrow but it looked to be 0.1875-0.250. Thanks
Question: Armature In Bosch 4000 To Much P...
I recently replaced armature,brushes, speed control, field and both bearings on armature. Now it sparks and it seized. upon opening Ive noticed a solid black residue around the armature and field. I also noticed that there is a little bit of play in the armature which I do not remember if that is normal! Doesnt the bearings and the brushes serve hold the armature in place? thank you
You have definitely replaced about everything on the motor that you can. If the armature has any play in it, it will usually rub on the inside of the field. That may be where the black residue is coming from. And I hope it didn't get hot enough to breakdown the insulation on the windings on the field or the armature. I would check the 2610996863 gear housing and the 2610018981 motor housing. To see if the bearings on the armature have any movement in either of them. If you have any play where the bearings seat I would think that would be the cause of your problems. The brushes will not keep the armature in place.
Thanks for your quick reply! I can confirm that there is play in the gear housing, but now the question would be why? The bearings replacements are the same size! Pulling my hair out on this one.lol What about the bearing bracket 2610911566, what part does it have to play? Does it align? THanks again
If the bearing that you replaced before was spinning in the 2610996863 Gear Housing, that may have worn the bearing seat allowing movement of the new bearing. The part number 2610911566 Bearing Bracket will keep the bearing from moving back and forth not side to side. Also make sure you did install the 2610996948 Rubber Ring in the 2610018981 Motor Housing.
Question: FIELD ASSEMBLY AND ARMATURE FOR...
LIKE TO PURCHASE A NEW OR USED FIELD ASSEMBLE AND ARMATURE FOR SUBJECT TABLE SAW FOR REASONABLE PRICE.
CAN ANYONE HELP? I SEE SOME ARMATURES ON EBAY BUT NOT FINDING FIELD ASSEMBLIES.
I spoke with the factory regarding the delivery date of the parts you are looking for. The 2610996866 armature has an estimated delivery date to them mid September. And the 2610996867 field has an estimated delivery date to them at the end of September. These are estimated dates they could come in earlier or later then these dates. Not very good news.
Question: Speed Control
I have purchased a new speed control for my model 4000 but can not find any direction on how to install it I am confused about which wire goes to which
Did you have any luck finding out which way the wires go? I have same problem???
Did you have any luck finding out which way the wires go? I have same problem???
If you contact a Bosch Factory Owned Service Center. They should be able to help you with the wiring or send you a wiring diagram.
Hi WJA, I contacted Bosch and they sent me a diagram for the two wires. after connection the saw worked good, soft started several times, and then stopped working again! WTF. If I bypass the controller (connect line in to motor) then then motor runs "fine". Could the controlled be bad out of the box?

I have this table saw , it worked great but then dyed out on me. I changed the control in motor, now it works but I have a lack of power , sparks at brushes contact and pulls 14 to 17 amps ?? brushes are good and so is the comutator ?? anyone knows what the problem could be ?? HELP Thanks :)
It sounds like you have a bad armature.Generally that's an indication of a short in one of the commutator bars.Do this: Remove one of the brushes and look down through the brush tube at the commutator with a light. slowly rotate the armature looking for burnt or deformed commutator bars.I think you'll find one is shorted.Hope that helps.Good luck.
Question: Bosch 4000 Table Saw Speed Contr...
So I've looked over all these comments and questions and I notice there have been problems with the speed control. My friend has the same saw and had reving issues, blew out the speed control unit and then it worked fine. I am now having the same problem, as it sounds the same and everything else seems to be in good condition. I tried blowing it out but didn't solve the prob. This saw has barely been used and I am really not pleased with it, that being said I don't want to purchase a new unit that will also fail in due time. Is it safe to just bypass the speed control, or will that cause issues with the saw? I understand I will no longer have the brake. Thanks in advance
No don't bypass the controller.The controller is also a speed limiter and soft starter.Bosch had some quality control issues with the controllers but my understanding is this is in the past. new controllers should be fine.Hope this helps.Good luck.
Question: Bosch Tablesaw Rod
You are correct the part number 2610996919 is the right part for the table top slide assembly.
Question: Bosch Table Saw 4000
motor was running real slow and gutless as hell. took it apart and seems all bearings are fine. what could this be/
Well the 4000 had problems with the speed control unit.Also slow running can be caused by a bad field or armature.But they will need to be tested for that. When the motor is running slow do you hear any sounds like bacon frying? If so you could have a bad armature.What do the brushes look like?Are the clean and shinny or do they look pitted and burned? Hope that helps.Good luck.
thanks tinkerdave well the motor pops like heck and the sparks coming off the brushes are big enough to weld off of. i pulled the brushes and they have a black film like car exhaust, they are also look minorly pitted. how do i test to see if the armature or the field is bad.
thanks for the reply yes the brushes seem to be somewhat pitted and burned. when i turn it on, there are tons of sparks around the brushes and it has a loud chattering sound that sounds like it is coming off the armature area. when the machine is off and i rotate it by hand there seems to be kind of a clicking noise. i did replace the rear bearing using a bearing puller so i do not think i bent anything. i pulled the armature back off and inspected it as well as the field. i cant see anything wrong. i was wondering how to check the armature and field to see if they are bad.
Question: Bosch 4000 Table Saw (0601476139...
I need a new rip fence and a new miter gauge and i don't see the parts or part numbers on the list of replacement link removed someone please help me with this problem?
Here are the part numbers for the items you are looking for.
Manufactures used to put the wiring diagrams on the parts diagrams. But for some reason the don't anymore. If you contact Bosch @ 877-267-2499 and ask for technical service, I'm sure they will be able to send you one.
Question: Bosch 4000 Table Saw Speed Probl...
I have a Bosch Table Saw 4000 and I have a problem with speed. When I turn the blade on it keeps getting interrupted the speed goes up then down, up then down. The brush make a lot of spark more than normal. And the brushes get really hot very quick. I have replaced the speed control and new brushes but I am still have the same speed problem. Anyone have any suggestions?
You need to replace your Speed Control Part Number: 2610997306. Hope that helps.good luck.
Hi thanks but I already replaced the speed control and the brushes and I am still having the same problem. Anymore suggestions of what it might be?
Thanks in Advance!
I'm sorry,I guess It serves me well to read the whole post before commenting. The problem with the blue sparks and the speed going up and down along with burning brushes out would suggest that there is a short in the commutator on the armature. You can remove it and a lot of time see the burnt commutator. You will need to have it check at a motor shop. Hope this is a little better help this time.Good luck.
Hey, thanks all for the info on the Bosch 4000 and the video on techniques for pulling the bearing. One problem, in using the 2 flat drew drivers to pop the bearing, it disintegrated. Now I have just the most inner hub of the bearing on the armature shaft; not enough to get a bite from the screwdrivers. I'm going to try grinding the remaining ring down to the point I can use a chisel to break it off unless somebody has a better idea. I don't want to nick the shaft but can't think of anything else.
Don't use a chisel.The best way if you don't have a puller is to use a dremel tool with a cut off wheel and carefully cut the inner race off.Generally one cut on the side of the race and you can pull the race off with your fingers.Hope that helps.Good luck.
Question: Bosch 4000 Blade Guard
I bought a used saw that was missing the blade guard. I like the saw but I'd like to have a guard. I don't see one on the parts list or the picture. Can you hel?
The part number for the complete blade guard assembly is 2610997205. If you just need the clear plastic cover it is part number 2610996900.
Hope this helps,
Question: Bosch 4000 Table Saw
I have a bosch 4000 table saw and when i turn it on it runs for 2 minutes then turns off then comes back on for 15 seconds then off and pretty much repeats this pattern. Can anyone help me figure the problem out im outta ideas.
Hi tr33: You need to replace Speed Control Part Number: 2610997306. Hope that helps.Good luck.
Question: Bosch 4000 Arbor Won't Spin
My saw suddenly stopped working partially through ripping a 2x4. The motor hums and the blade will spin just slightly(like a 1/2" at a time) when turned on. The arbor won't turn under finger pressure.
I haven't found this specific issue in the forum and am in the process of disassembly which may reveal the problem but if anyone has some insight it would be greatly appreciated. Thank you.
It was the bearing on the field side of the armature. It is frozen up solid with a bulge on the side. My new question is do I need to disassemble everything on the blade side to get the armature out? I was going to replace both bearings while I had it apart. Thanks in advance for any help.
Hi gettes,No you should just be able to take the brushes out and remove the four screws that hold the motor housing to the front bearing housing and slide the housing off the armature. You really don't need to replace the larger front armature bearing as this almost never goes bad.Make sure your blowing the motor out with compressed are on a regular bases as this keeps saw dust from clogging the cooling vent in the rear of the housing. Hope that helps.Good luck.
Question: Bosch Table Saw
Thanks so much for the quick reply, Tinkerdave. When you say "control module" if you are talking about item #12 "speed control" on page B above, that is what I replaced. I bough if from this web site. I am absolutely certain I wired it correctly. More details: A piece of wood got crooked and bound up for less than a second before I threw the switch off. I've have much worse binds than this on other saws with no problems. But when I pulled the wood out and turned the saw back on, the saw did as I described: It turns backward for an inch and stops. A current-hum sound comes out of the the motor but I don't let that go for more than a half second before flipping the switch off. If I grab the blade and spin it forward as hard as I can and then flip the switch on, it will turn very slowly for several revolutions and sort of clatter until it stops. Those are all the details I can think of. Thanks in advance for any advice.
Hi Joalmorris, based on what you tell me I can't think what else it could be.I've had a number of saws that have come into the shop most have had something like that happen to them. The saw will run in reverse,the saw will run at a high rpm,or run and chatter like your explaining. I still believe you got a bad speed control. The control unit does a number of things 1. it controls the speed brake. 2. It is a RPM limiter.3.It controls the soft start. It sounds like the controller is stuck in soft start and brake at the same time.The only other thing that could cause this is if the brake lead from the field is broken so the controller is not getting a signal from the field and thats whats causing it to be wonky.
Tinkerdave, stop telling people that a table saw running backwards needs a speed control. the speed control can NOT cause the saw to run backwards. it is always the field.
also, there is no brake in this tool. it can NOT be stuck in soft start and brake.
stop making up answers. you are costing people time and money.
Question: Bosch 4000 Table Saw
Out of the blue my table saw stopped working. When I turn it on, the blade turns backward about an inch and then stops. The motor continues to hums like it wants to run. I turn it off immediately. I've read through the advice below and most people think the speed control is the problem. Well..I bought a new speed control and replaced it. It still does exactly the same thing. Does anyone have a Plan B suggestion for me?
Hi Joalmorris, The fact that the motor tries to turn backward and then stops and hums leads me to believe also that your control module is bad.The control module is trying to apply the brake and this is why you have slight movement in reverse.Bosch has had problems with this module and we have even gotten them bad out of the box.Are you sure you have it wired back up right. Did this problem just suddenly appear or did you notice the saw doing other things also.As much information as you can give will greatly increase the chances that someone can pin down what wrong with it.sorry I cant be more helpful.
there is no brake in this tool. the speed control/control board/module is a soft start and electronic feedback, which controls the speed. it limits the no load speed so there is some headroom to add some rpm's when under load to keep the speed constant. it is wired in line and cannot make the saw run backwards.
if it is trying to run backwards, you have an issue in the field windings.
Question: Bearing Replacement 101
On the Bosch table saw model 4000 page B of the exploded view, how do I remove the bearing from the armature (fig. 13)
I have a Bosch 4000 Table saw, it is between 2 & 3 years old. Serial # 79114 1060.
Well looked after, little use, never got wet. I was using it yesterday to make some rip cuts on some trim. I had just started a cut when the power tripped out, the motor was not being overloaded. I re-set the switch on the consumer unit, and when I re-started the saw it now only turns backwards and at approximately half speed!!!
I have plugged other tools into same socket without the same result and I have plugged the saw into a different socket with, unfortunately, the same result of backwards and slow!
Do you have any ideas what has happened to my saw?
What is the warranty issue on the motor, which seems to me to be the issue?
How much is a new motor and can I fit it easily?
Any help or advice would be greatly appreciated before I take it to a repair centre.
Hi Simon, Your speed control unit is bad.The reason its turning backwards is this controls the brake which reverses the motor for a fraction of a second the brake is stuck in the on position.Replace the speed controller and this should fix your problem. Hope that helps.good luck
I agree with Tinkerdave with his assessment of your problem. The speed control on that saw is the cause of a few problems with the motor on that saw.
Bosch 4000 table starts and runs backwards slowly! changed speed control still have same problem any suggestions?
such bad advice here. sorry to all the people who have followed some of the bad advice here and wasted their time and money.
as D29 pointed out, replacing the speed control on a saw running backwards is a waste of time and money.
because the issue is the field.
THERE IS NO BRAKE IN THIS TOOL. there is zero possibility that the speed control is trying to brake. this is a made up answer that sounded plausible to someone who does not really know the answer.
Question: Speed Control
If all the electrical components have all check okay. Your best bet would be to replace the speed control. It is a PC board that controls the motor's speed when under a load and gives you optimum power when needed. It has in it a circuit breaker/overload to protect the motor from overheating and damaging it.
Hope that helps,
Usually if the motor is running slow and backward it is because the crossover wire in the field has shorted out and the field not the speed control will need to be replaced.
the speed control will not make it run backward. that is cause by the field being shorted out.
I recently bought a Bosch table saw ( used ) and looking at this forum for information. Wondering - where is this "Speed Control" located on the saw? I don't see it ... even in the drawings. Wanting to learn as much as I can before something goes wrong!
If you pull the parts diagram by clicking on the model Bosch 4000 below and find item number 12 you will be able to get an idea on where the 2610997306 speed control is located.
Hope this helps,
My table saw the 4000 started to run real slow with no power? Is it the control module?
If you saw is having that type of problems. My guess that it is your 2610997306 speed control.
Hope that helps,
what if you by passed the speed control and its still doesn't work
Question: 4000 Table Saw Motor
I really like the features of the saw. Motor is a different story. Right now I have replaced the brushes since the motor did not run correctly, this being only several hours aftergetting it repaired. What could cause this? Sounds like Bosch has major problems with motor units. Need some direction.
Not knowing the problem you are having with your saw motor. We have noticed in the past, problems with the PC board failing. When this happens there are several things that could happen. For instance loss of power, motor not running at all, & motor running backwards. If your brushes are wearing out and you are seeing arcing from the motor you might also have a defective armature. I hope this helps.
Question: Bosch 4000 Table Saw
Hi - just ordered field, control board and brushes. This will be the third time. First two were done under warrantee a couple years ago. I like the saw and stand and its cheaper than a new saw so am fixing one more time. On the other hand....was wondering if the field/board have been imrpoved so maybe...just maybe....it will last a little longer. I baby this thing by blowing out motor and keeping it on good power. Really a weak motor.
Hi,The small speed control board has been a problem for Bosch for 3 or 4 years. I'm not aware that Bosch has published a service bulletin in regards to it.I too have replaced a number of these circuit boards.A lot of these parts comes from China and their quality control seems to be up and down on stuff like this.Sorry I can't give you better information.
Question: Bosch 4000 Tablesaw
I am replacing a broken gear cover with a new part.I can not figure out how to remove the primary shaft from the old broken piece to install in new part.I see no visible clips or retainers.Does the nut on the shaft have to come off? If so how is the shaft secured to turn the nut?Is the nut left or right thread?Or does the bearing on the opposite side have to be pulled to enable the shaft to slide out?Anybody know?

The housing comes off after you take out the GUIDE PINS, They have 2 C-CLIPS each on the inside of the UNDER COVER. Then you have to remove the LEVER that sits on top of the Housing, There are two screws under the lever which will release your housing. I hope this is what you where asking. Good luck
I have the same issue. Read the response below, but can't find those pins or clips anywhere... anybody have a diagram or photos that would illuminate the situation?
If you click on the parts diagram for the Bosch 4000 Table Saw below. On page B item number 56 part number 2610996862 is the Guide Pin and item number 201, part number 2610992380 is the C-Clip, and item number 46, part number 2610996874 is the lever. These should be the parts that caroj59 is speaking of in his post.
