Hitachi G12SA Angle Grinder Repair

Repairing a stuck power switch, replacing motor brushes and installing a new grinding wheel. I purchased this grinder back in the '90s as I recall. This is now the 2nd time I've replaced the carbon motor brushes. This model driver uses ~1/4" square brushes with built-in shunt and spring. This is very similar to the brushes used in many Toyota and Honda vehicles for the in-cabin blower motor. I've replaced the blower motor brushes in my Toyota 4Runner once. Not sure what was wrong with the switch, I didn't get it on video, but it was stuck in the off position. All I did was remove it, open it up and put it back together and it's working fine. I've really liked the Norton Charger Plus grinding wheels with the Zirconia Alumina / Aluminum Oxide abrasive blend. They cost about twice that of a normal Aluminum Oxide wheel, but last many times longer. Since I use this grinder extensively in my fabrication business, not having to change wheels as frequently is a big win. I later cleaned up the housing with the combination of a wire wheel, followed by a cotton buffing wheel and finally a wipe down with a rag and some acetone. You can see the finished result in the video thumbnail. Our web page with blower motor repair and carbon brush information: http://www.4crawler.com/4x4/CheapTric...
