Good fit
While the old rubber boot on the 20 year old motor was still ok, it’s a good part to replace because it dampens motor vibration. This one had a good tight fit. Hope it lasts as good as the original.

When the bearing seized it burned the rubber ring. I ordered it because I saw it on the schematic. I’m glad I did As it was an essential part.

Use a bearing puller if you have one to get the old bearing off the armature, otherwise see the video on bearing removal on the eReplacementParts website. A rubber ring rather than a retaining clip is used to hold the bearing and armature assembly against the rear motor housing and the old ring, being black, can be hard to see in the dep
... Read moreression in the motor housing. It may still be usable but it\'s probably better to install a new one in case the old one got torn up when the bearing failed. Install the new rubber ring, seat the bearing using the socket/mallet method (see video) and press the rear motor housing against the main housing enough to get the screws started. Torquing down the screws will draw everything snugly together. When you first start the motor, there may be a smell of burning rubber because the moving parts of the bearing may rub for a few seconds against some of the rubber ring, but this won\'t last very long.

5.) Removed motor housing from cast gear box/blade support (4 screws). Armature remained in gear box.
6.) Removed armature by pulling out of gear box and front bearing
7.) Removed front bearing retainer (2 screws) and removed bearing with inside puller. Replaced with new bearing and re-attached retainer.
8.) Removed rear bearing by cutting off with dremel and cutting wheel. The outer bearing had fallen off with ball bearings so only inner race remained on armature shaft and nothing for puller to grab to...so had to cut off.
9.) Replaced new bearing on shaft and cleaned armature with damp rag and a little brake cleaner.
10.) Removed wire nut caps from field wiring and rear motor cap (which contains speed control board). Removed 2 bolts that held field in motor housing. Removed field from motor housing by tapping out from rear.
11.) Replace with new field. Reattached wire nuts and tightened 2 bolts.
12.) Added grease to armature shaft gear end and reinstalled cast gear housing/blade support.
13.) Reassembled saw in reverse order
14.) Replaced saw blade
15.) Plugged in and ran like new. Parts for $100 saved my $600 table saw. Tool retailers wanted $300 minimum to begin repair which would be used towards the final repair bill. Glad I did it myself, but you should have some mechanical and electric motor knowledge and able to keep parts in order during disassembly.

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
... Read more 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.

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.

The motor tried to run but couldn\'t. It just mostly growled.
I took the table saw off of the stand and turned it upside down. At first I thought it was just the brushes and when I took the old ones out they were not worn down but were chipped off at the contact end. So I checked the bearing and sure enough it was seized up. Ordered an new one and a rubber ring. I took the back end of the motor casi

If you are replacing bearing exposed on brush end...do it while the armature is in the saw.
Removing the armature requires screws and adjusters on the blade end to come off...you lose all the adjustments and cost yourself an extra hour.
Pull bearing...you need just the right size puller.
Use a socket or pipe to push the new bearing on...not a serious tight fit..you need to push/pound on the race closest to the shaft to not damage the bearing.
Rubber cup is in plastic housing cap...mine was damaged....right puller was my biggest hassle...took one apart and used it differently than intended!

9. Remove and replace rear bearing.
10. Cleaned gears and housing.
11. Repacked axle grease around gears, bearing and inside housing
12. Reassembled in the reverse order.
Note: The hardest part of this is reinstalling the two screws that hold the armature assembly to the front gear housing. There is a metal plate that the two screws that go through the housing into the metal plate on top of the armature. That plate is free-floating and there is about a 1/4\" of clearance between the housing and the plate and the top of the armature assembly. Gravity is your enemy trying to get the plate and the screw to line up because there is NO room to put a screwdriver tip or anything inside the space. I tried for over an hour to get one of the screws started again with no success. Finally I went to my screw bin and found a 2\" screw the same size and thread pattern as the original and use my scratch awl to line up one side of the plate to the hole. I use the long screw in the opposite side of the plate to temporarily screw it in and bring the plate to the top, where it was supposed to be, then removed the scratch awl, and put in one of the original screws and tightened it. Then I was able to remove the long screw and put the other original screw in the other side. After that was done I tightened both of the original screws and and rest took about 15 minutes. Maybe this will help someone else in doing this bearing replacement?
This repair was on a Bosch Model 4100 table saw, which by the way is a GREAT saw!
First I searched the repairparts website for a manual and diagrams. Removed the motor housing which required enough force and prying with a screwdrive to worry me I might be doing damage. (Others\' reports said this part was \'easy\'. Hah!)
Once the rear housing containing the brushes and rear bearing support was free the fie
... Read moreld assembly came away easily. I did realize, late, it would have made things easier to have removed the brushes first, and then to separate the case.
The rear bearing, housed in the rear housing, had burned up the rubber ring. A mess. It was an awkward reach to dig out the hard, burned-on residue of rubber in the rear housing. I used a drill to grind part of it away.
I had ordered the rubber ring, and the new bearing, and new brushes. Had to keep digging to get enough of the old rubber ring out so the new one could seat. At that, it took a good deal of effort to get it and the new bearing seated. That part was only complete when I tightened down the bolts that hold the rear housing and field assembly to the front part of the motor housing.
The old brushes looked about 85% wear remaining after 6 years use on remodel projects.
I would like to have replaced the front motor bearing also but could not figure out how to tear down that end without a sense of risking further damage. Did not find complete or clear enough instructions on that part.
The how-I-fixed-it accounts of quite a few others really helped.
1. Removed the bearing.
2. Cleaned out the armature.
3. Installed the new bearing.
4. Installed the new brushes.
5. Installed the new motor cover/casing.
Thanks to the e-replacement on-line forum, I was able to diagnose the problem, order the appropriate bearing (from VXB.com), and complete the rebuild. As suggested,
1). remove the blade,
