It feels like a roasting temperature up here in Canada due to the high humidity.
Meanwhile, last year, my air conditioner started making a ton of noise. But that was at the end of the summer. So I let it be. Today I removed it from its cover and had a look at it. I knew that the noise was due to dry bearings.
The trick was how to re-oil them while not having to take the motor out. These motors are typically brass bearing types. So I knew that if I drip some oil on the spindle it would make its way to the bearings. It worked. It just kept on sucking up more oil and that is because partially surrounding the bearing area there is an oil absorbing material designed to store a supply of oil for a long time period.
But that was just one end of the motor. The other end was difficult to get to.
So I used my old ear wax cleaner and a plastic tube from within and old plastic spray bottle. The plastic tube is inserted into the ear wax cleaner thus producing a long bendable extension. I then filled it up with oil and its extension flexibility allowed me to get the the other end of the motor and load it with plenty of oil.
Now it's back to being nice and quiet again. Job done.
