Loud, high-pitched squeal, then motor would not start after cooling down
I surmised a bearing issue and validated my idea via internet searching for Bosch T-4000 table saw maintenance, finding several articles on bearing, brush, armature, and field replacement, but no articles on performing bearing lubrication or maintenance. e-Replacement had very good diagrams of the saw and saw motor, so I removed the motor and found the bearing on the commutator end of the armature badly burned and rough, the rubber ring melted and the end of the motor housing melted. I ordered the parts and when they arrived, I replaced the bearing, rubber cap that holds it securely in the motor housing, the housing itself, the brushes (even though they looked to be in fairly good shape and just slightly chipped on one edge), and transferred the necessary parts from the old housing.
The armature and the field both had a thin layer of the melted rubber ring and the melted end of the housing over much of their metal surfaces which I carefully sanded off with very fine Wet-or-Dry sandpaper (armature and commutator) and a cylinder hone (for the field).

The hardest part was fitting the motor housing end cap back onto the motor housing due to the very limited space and getting the wires and butt-joints into their exact locations so that the cap fit back on and seated into place. I used an old bicycle spoke to prod the wires and butt-caps into place to get everything aligned. Take a picture, take notes, or make a drawing of how the wires fit in the cap if or when you remove it from the motor housing to save yourself the time it took me.

I have now ordered the other 3 bearings in the motor, though the rest seem okay and I was able to carefully pry out the seal from the other armature bearing and refill it with grease before putting everything back together.

I will also try to seal any excess holes in the housing for the vacuum port so that I can keep the motor cleaner. I will also always connect a vacuum hose from my Dust Deputy and shop vac when using this saw to keep sawdust out of the motor.

Repair Difficulty:

Time Spent Repairing:

Tools Used:
Screwdriver, allen key, snap ring pliers, gear puller/installer
The rear bearing on the armature seized and the resultant heat melted a section of the motor housing causing the table saw to lock up.
Bosch 4000 table saw repair. Remove the rear motor housing (3 Phillips screws) then uncrimp the 3 wires attached to the field winding/carbon brushes. The next step is to remove the four phillips screws that hold the motor housing to the inner gear box. Pull housing towards you to remove. I used a gear puller to remove the bad armature bearing, then proceeded to degrease and clean the armature with electromotive cleaner. Reassembly is the reverse of disassembly.

Question: Motor Housing

BigDisneyFan2

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?
WJA
Hello BigDisneyFan2,

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.

-WJA
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...

Georgao

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
WJA
Hello Georgao,

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.

-WJA
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
WJA
Hello Georgao,

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.
