I bought a starter off ebay from a reputable person (on this forum) a couple years ago. The starter body has a hole in it. It goes all the way through. I dont recall the kw's, but they are higher than normal. My factory unit doesnt have this hole. What would this be used for?
Probably used for a over a case mounting point. And to look down the hole and it's just a casting that's sealed off, no dirt will enter the motor body? Ignore it.
