The motor went out on my Milwaukee Tool shop vacuum after 30 years of reliable operation and, unfortunately, the company no longer supplied parts or service for these older machines. I noticed a quot115330 Lambquot part number stamped on the motor housing and did an online search to see if the motor was still available. I was pleasantly surprised to find that it was. Centralvacuumonline.com had a picture of the motor which looked identical and the specifications which matched the size and amperage of the old motor. Based on consumer ratings and a great price I ordered a replacement and was not disappointed. The motor came in well packaged and faster than I expected. In a short time the vacuum was up and running like new again. I am very pleased with this company and recommend them to all in need of replacement vacuum parts.

Ask a Question

When To Replace Brushes vs Motor
Question: how do you know if the brushes need replacement?
CVO's Answer:
Motors have two carbon brushes that conduct electricity across an armature spinning in the center of the motor. The brushes start off at about 3/4 inches long and go down over time. There is a spring behind them applying pressure. By the time a motor has run 800-1100 hours, which is a life span, it is too late to change the brushes. The armature is worn, bearing are not as solid, and new brushes will grind down extremely quick. If you don't know how long your vacuum has been run you can check a couple things in order to find out if the brushes should be replaced. First see if the bearing are solid. Push on the center rod, the armature running from top to bottom, to see if there is any play. If there is any play then replace the motor. If it is solid then next check where the brushes rub on the armature. There are plates there that should be shiny and mostly clean. If they are pitted and blackened then replace the motor. If they look good then check the brushes. If the brushes are worn down to 3/8" then replace them both. Sometimes one wears much faster than the other.
