In addition, you cannot press on parts to speed up work. Abrasive wheels work on the principle of removing the top layer, and therefore do not require pressure.
Prying off with a screwdriver, remove the gearbox cover assembly with a secondary shaft and gear. The bearing of the output shaft turned out to be working, without backlash and jamming.
But the front armature bearing - completely crumbled. The bearing balls were in the gear grease and the small gear retaining ring was worn on one side. To replace the front bearing, you must first unscrew the armature contact brush caps and remove the brushes.
Then we unscrew the four screws securing the grinder gearbox to the stator and remove the armature together with the gearbox housing.
To remove and install the armature gear retaining ring, you need to make a simple tool. For this I used old scissors. The ends of the scissors on emery were ground off, as in the photo.
This is the view I got from my retaining ring. For the convenience of mounting the retaining ring when assembling the reducer, the ends of the scissors were heated red-hot with a gas burner and bent at right angles to the plane of the scissors. Then they were again heated and cooled in engine oil.
After dismantling the armature gear, I removed the armature from the gearbox housing. This is the view of the front armature bearing.
The outer cage of the armature bearing is removed from the gearbox housing by lightly tapping on a metal screwdriver inserted into the groove of the cage from the inside of the gearbox housing. It is important not to skew the cage when pressing out.
But the inner bearing race was tightly seated on the armature shaft.
To dismantle it, I used a standard tapping tool holder.
Studs were unscrewed from it for rotation when threading. And the rod holder itself is installed on the bearing race, so that the screws for fixing the rod fit into the groove of the bearing race. Then tighten the screws evenly on each side and thus securely attach the holder to the holder. Now we grab the puller with the paws of the tool holder and remove the holder from the shaft.
New bearings must be filled with grease. To do this, you need a sharp awl, Litol 24 grease and a mandrel for mounting bearing caps. To lubricate a closed bearing, you need to remove the cover by prying it with an awl, as in the photo.
Now we fill the bearing with grease and put the cover in place.
To put the cover in the bearing without damage, you need to select a mandrel in diameter slightly larger than the outer diameter of the bearing cover. I used a socket wrench head.
The bearings are lubricated. Press the front bearing into the gearbox housing using the outer race of the old bearing and fix it with a flange.
At the anchor, the anchor collector is cleaned with P1000 sandpaper. With a stationery knife, carefully, without much pressure, we clean the paths between the collector lamellas. And after these operations, we carefully wipe the collector with a cotton napkin moistened with white spirit or other solvent.
Next, you need to press the armature shaft into the inner race of the front bearing. To do this, place the gearbox housing on a wooden surface with the bearing facing up. We insert the armature shaft into the bearing cage from above and lightly tap it through the mandrel, along the rear armature bearing we put the armature in place.
We put a small gear on the armature shaft. If, after installing the gear, the groove for the circlip extends beyond the end of the gear, then the installation is correct. We put the retaining ring in place.
If the groove does not come out due to the end of the gear or is halfway out, the shaft must still be seated in the housing.
After these operations, remove the old rear bearing from the armature shaft and install a new one. We place the armature with the gearbox in the stator and tighten the four screws securing the gearbox. We check the shaft for rotation. The shaft should rotate easily without jamming in the bearings. We put in place the contact brushes and screw their covers. Now we put a special lubricant for angle grinders in the gearbox grinders and put in place the cover of the gearbox with the secondary shaft.

The upper bearing is checked by weight holding the gearbox vertically with an anchor downwards, we twist the shaft and with our hand we feel whether the balls are gnawing at the cage, if there is wear in the balls, you will definitely feel it in your hand.
in the video you did not check it correctly, the case should not be twisted in your hand, but the anchor should be unscrewed, then in your hand from the case you will feel the vibration of the balls gnawing on the inside of the clip. Because the body weight is only 60-80 grams and it will not give any load to the bearing. Always if there are two or more bearings on the shaft, then the bearings always change only in pairs. do not spare the money, the 629ZZ SKF bearing costs no more than 200 rubles or 80 hryvnyas and it is cheaper than screwing up a grinder or pulling out the remnants of torn metal from your body in the hospital.
