After the ceiling fan is disassembled; first remove the blade; then heat the electric soldering iron; weld the motor wire soldered to the capacitor; remove the starting capacitor. Loosen the fastening screw on the pipe; then tighten the shaft with a wrench Rotate the upper two parallel planes counterclockwise; separate the suspension tube from the motor shaft. Then use a Phillips screwdriver to unscrew the three tightening screws of the upper and lower end caps of the motor; clamp the edge of the upper end cover; use a wooden hammer along the upper end edge of the cover Gently tap; until the upper end cover is removed. Pay attention to only use wooden hammer; it is certainly not allowed to directly hit the interface with a hammer. Otherwise, it may deform the external thread of the hollow shaft; the shaft and the pipe cannot be connected. Device; make the armature invalid. Others; should also pay attention to two points: First, can not knock out the three power lines in the shaft hole, and second, can not break the motor coil or damage the insulation.
After removing the upper end cover, screw the adapter from the head and lift it up; tap the edge of the lower end cover; the lower end cover can be left. You can check the bearing wear condition; if it is only smooth grease dry; Directly add high-temperature smooth grease; do not add general butter or engine oil; otherwise, when the device is installed, the smooth oil will be blown out from the ceiling fan when it is heated; if it is a motor bearing, the bearing will be severely worn; New bearing; if the bearing is too dirty; should be removed and cleaned and dried with gasoline, then apply excessive smooth grease; use it from the head device. But when using gasoline to remove the ball bearing; must pay attention to fireworks; avoid static electricity; avoid ignition Gasoline attack fire.
