method:
Loosen a few self-tapping screws or screws outside the drill; flatten one half of the outer casing; the structure of the new hand drill is semi-embedded, that is, all the mechanical and electrical components are installed in the other half of the casing. Carbon brush, then take the end of the drill chuck, then gently lift the motor to take out the rotor (do not touch the enameled wire), wipe the commutator on the rotor (the one that is in contact with the carbon brush), if it is too dirty or worn It can be sanded with sandpaper and polished with water sandpaper or metallographic sandpaper.
If the bearings in front of and behind the rotor are sealed, the outside can be wiped clean. If the seal is broken, it should be replaced in time. Clean the spiral pinion in front of the rotor and clean the oil inside the casing. Clean the helical gear and the bearings at both ends (or bushings) on the drill chuck.
Put the unloaded Dongdong back, first install the rotor; then install the drill chuck helical gear; install the carbon brush, if the carbon brush is shorter than 7-8 mm, it should be replaced in time. The carbon brush should be flattened, and finally find a little "Mobil" or "Shell" grease added between the gear pair and the bearing (or bushing). All the parts should be installed and the flatness can be checked. Tightening the screw and turning it by hand feels no stuck, so you can turn it on. 
How to maintain electric drill
Because the electric drill needs to be ventilated and dissipated, the internal dust is used for a long time. The dust will make the lubricating oil on the gear and the bearing (sliding sleeve) mixed and deteriorated to absorb the wear and tear, especially for the alternative. In order to ensure the rotation accuracy of the electric drill and reduce the excessive clearance caused by the wear of the bearing (sleeve), it is extremely necessary to maintain the clean interior and grease lubrication.
