DeWalt 4,1/2 inch angle grinder suddenly wouldn\'t start and was completly dead.
When the brushes went out on my angle grinder it was sudden, there wasn\'t any shuddering or anything like that. I thought it might have been the switch but what I realized when I opened it and looked at the brushes is that the brush itself has a spring loaded button inside it. When it get to low the little button pops out and stops the

The tension arm is red and has a spring to hold it down. Carefully pull the spring back with pliers and then pull the brush out. the one on the other side is a bit trickier to get at though. You\'ll have to gently pull the whole apparatus away from the case. This back case holds an armature that activates the switch which is in the back of the tool. try not to jumble things to much and make sure that you keep in mind how things go back together. I would suggest that if you find a bad brush on the first side like I did then just order new ones before you take everything apart, by the time you get them in the mail your memory may be a bit foggy on the reassemble procedure. I couldn\'t get the switch to line up at first but then I realized that the whole case was turned 90 degrees the wrong way. Once I figured this out the hardest thing was getting the wires to line up where they were. If the case doesn\'t want to fit perfectly back at first then just keep gently pinching it back and forth for a little while, the internal parts fit very tight in the case. So far the tool is working fine for me.
I removed the four screws from the gear housing case to view the ring and pinion gears. They were extremely worn and did not engage. I removed the nut locking the pinion onto the armature shaft. Then I removed the 4 screws from the housing and pulled the housing from the body of the grinder. I installed the new gear housing replaced the 4
... Read more screws to the grinder . I slid on the new pinion and securely tightened the holding nut. I greased the gears and replaced the gear case lid with the 4 securing screws, Don\'t forget the small rubber seal. Mine was fine so did not replace it just used the old one. I turned the unit on and put it to use. Works better then new.
