HOUSING MOTOR 200058016

I removed all the screws from the drill body using an extended length torx bit. I believe it was a number 5. Pulled off the gear box, then pulled out the armature that had the bearing pressed on. To remove the bearing required a little creativity. I just slid a pair of needle nose pliers under the bearing and used a vice to support the ar ... Read more mature. I then used a pinch and hammer to tap the armature shaft out of bearing. I then carefully tapped on the new bearing. The entire trigger assembly needed to be disconnected to allow removal of the field from the old housing. That essentially allowed the field to slide out but when installing the field into the new housing, I had to carefully tap in the field assembly to seat it correctly. Care needs to be taken when removing one of the black wires into the trigger assembly. There is a hole that one of the black wires inserts into it which has an internal clamping mechanism. A very small screwdriver was used to insert into a hole adjacent to the wire that will release the internal clamp. IGÇÖd recommend that photos be taken before removing wires so you will know where the wires reconnect to the trigger assembly and brushes. I assembled in reverse order and the drill works as good as new. What most likely saved me from further damage is I stopped operating the drill upon first seeing it malfunction but not before the drill body housing became melted and the bearing seat became out of round thus allowing the armature to flop around inside the field. In all I think it cost me around $30 to fix.
