Craftsman router 175060
I have a Craftsman router 175060. Most parts are no longer available. Turned it on. Got up to speed. Started going up and down (speed and light). After stopping and restarting 3 or4 times, it will not start. Every once in a while, I can get it to rotated about 1/8 to 1/4 inch when I push in the switch. I can rotate the shaft and knock on the side and it will usually do this. Once it tries to turn, it will not move again until I rotate the shaft and tap on the side. Hoping it might be brushes that are getting stuck. Tested the switch and it is ok. Power is transferring thru it wil I push the switch in. The switch, armature, and most of the other "61 parts" are no longer available. Tried to take it apart to check the armature and brushes. Can't figure out how to take the fan off of the top of the unit after I take off the top cover. Looks like it has a tiny pin in the middle of the fan. It is not a screw and tried to push it in but it won't move. The top cover on the motor will pull up a little bit all the way around and may be able to come over the fan. The lock switch/slide looks/acts like it has to be removed before the top will come off to allow access to the armature, brushes, etc. Does anyone know how to remove the lock switch and/or fan?
Thanks fopr your help.
