How to disassemble and assemble the end cover of an electric motor?

Before disassembly, make a mark at the seam between the end cover and the housing for restoration purposes. Then unscrew the bolts that fix the end cover and slowly pry off the end cover with a screwdriver (both unscrewing the bolts and prying off the end cover should be done symmetrically along the diagonal). Make marks on the front and rear end covers to avoid mixing them up during assembly.

During assembly, align the marks on the casing and end cover, put on the end cover, insert the screws and tighten them (tighten the screws symmetrically along the diagonal in several steps, don't let some be loose and others tight to avoid damaging the end cover), while rotating the rotor to check if it moves smoothly.

How to check if the electric motor bearing is running normally?

Common methods to check if the bearing is running normally include listening to the sound and measuring the temperature. To listen to the sound of the bearing running, use a thin iron rod or screwdriver, with one end against the bearing cover and the other end close to your ear. If you hear a uniform "sandy" sound, the bearing is running normally; if you hear a "hissing" metal collision sound, it may indicate insufficient oil in the bearing; if you hear a "rumbling" impact sound, it could mean some of the rollers in the bearing have been crushed. To measure the bearing temperature, use an alcohol thermometer (or use an infrared thermometer to directly measure the temperature of the front and rear bearing end covers of the motor). You can attach the thermometer to the bearing cover for measurement. The rolling bearing should not exceed 95℃, and the sliding bearing should not exceed 80℃. If you don't have a thermometer, you can sprinkle a few drops of water on the bearing; if steam comes out, it indicates the temperature has exceeded 80℃; if it makes a "hissing" sound, the temperature has exceeded 90℃.
