Reply to "Pittman motor question"

Joe,

Here is another idea. Since you have had the motor apart did you clean it with an electronic motor spray? Plus on the comutator (the copper segments on the end of the arm) look to see if there is a build up of dust from the brushes in between the segments. If there is take a hobby knife and clean it out. Be careful not to scratch the segments.

Some times when the brushes wear and the dust builds up there can cause a squeal.
