Electric motors have ball bearings inside that need oiling to prevent destruction of the bearing and overheating of the engine. A regular oiling, about twice a year, will keep your fan motor from failing. If you have the owner's manual for the fan, look for the instructions on what oil to use for lubrication. Use SAE 10 or 20 oil if this information is not available, since it is a medium-grade oil suitable for most purposes.
Things You'll Need
- Oil can
- Allen key or wrench
Wipe off the outside of the motor to remove all dirt and debris.
Mark the end shields of the motor with a pencil so the correct position for reassembly is known.
Remove the bolts for the end shield using an Allen key or a wrench, depending on the connection.
Insert the end of the oil can into the oil ports of the fan motor and place one to two drops in each port.
Reassemble the fan.
