The product works perfectly now but the product has some flaws that you should be aware of, the screw that holds the brushes doesn't go all the way so I had to use a drill to open and deepen it them to extend the reach of the original screw. after doing that i was able to solve the problem. If you don't do what I just did you could damage the guard and the screw won't tighten and the motor will need to be replaced as the screw goes into the motor shaft which is plastic and easily damaged. So be aware, if you're not skilled, just don't and get genuine parts.
