Sioux bearings stuck

>I can't get the bearings off the armature of my Soiux close quarter drill. I can't find a puller small enough at the auto supply places. I tried tapping the shaft till it started to mushroom. Any suggestions?

>A couple. Try a search, this topic has been mentioned several times. One approach is to grind the side of the bearing very carefully until you can peel it off the shaft. The other is to gently pry from the underneath of the bearing using a screw driver or some such. Of course if it has already mushroomed that is going to be a problem. You might also try to fashon a puller of some sort using iron or steel plate with holes and bolts. The main thing is to be careful not to damage the armature. Might try putting the plates under the bearing and holding the entire thing in a vise and try taping again. Finally you can get the armature part from Milwaukee (same drill different color)and new bearings from Boca Bearing in Florida.

>Just grind the bearing on 2 opposite sides until almost through; then catch one of the halves with a pair of Vicegrip pliers and twist it off.The outer race is easy but the inner one is where you have to be careful and not grind the shaft. It is a 10 minute job.

>I have not taken one of these apart yet, but what I would use is called a bearing separator. It consists of 2 thick, hard steel plates held side be side by 2 long bolts passing thru them. The inside is counterbored so that the plate can slip into a small space between the bearing and armature. I then place it in an arbor or hydraulic press and push the shaft out. A bench vise could also be used to support the separator and using a brass punch or piece of aluminum, or even hard wood on the end of the shaft, hit that with a heavy hammer, not the shaft itself. I will take a picture of a small bearing separator and post it, a little later.
