if the lubricating oil less can be timely supplement, if the lubricating oil deterioration should be all replaced, at the same time in the overhaul regardless of the motor bearing lubricating oil situation, should be all replaced.

Motor bearing refueling method

1, usually, small repair supplement lubricant, can according to the situation of the bearing within the pendulum lubricant gouge off some, and then supplement a little lubricant;.

2, overhaul all replacement, first of all, the motor rotor pull out the stator, then use gasoline to clean well, and wait for all completely dry, and then refueling and refueling quantity for the bearing room gap 1/3-1/2 can, can not refuel too much otherwise the bearing is easy to heat damage.

First of all, choose the correct grease, then add grease according to the following requirements.

① Pay attention to the surrounding environment, must keep the grease pure, do not let the dust, sand blown into and metal particles and other impurities mixed in.
