How to get bearings off shaft?

[clevinski]

Many times they are not that tight and I will first try this first. I screw a nut onto the threaded end to protect hem and slam the shaft nut side down on a a chunk of steel. The momentum and fast stop the shaft and the bearings will fly off. You could also try a super thin chisel between the gear and the bearing. have to be careful not to burr the gear. Those pullers are not cheap and if your only going to do one, take it to an auto machine shop and they can get it off for you for cheap. Many old manufacturers would drill small holes in the face of the gear so all you did was to use a pin punch and tap the bearings off. Rich

Hi, Rich,

Unfortunately, in this case, they WERE that tight! When the first one finally broke free, it sounded like one of the bolts on the separator snapped. My immediate reaction was to yell, "What the [colorful language deleted]!" Pressing the shaft back into the new bearings also took a LOT of force with the arbor press, but they finally seated. I tried making a wedge to drive between the bearings to start moving one, but it wouldn't budge. (Though, I was not using a chisel and the angle was 30°, probably too steep for this to work.) But the bearing separator/puller did the job, and now I'll have it for next time!

BERINING is toast so why save it only way is whizzer or chop saw. Live saver those sealed bearing's slit it for oil with cut off blade.

GK,

I wasn't trying to save the bearings; I was sure I could get the outer races and the balls out without problem. My concern was cutting the inner races without hitting the precision diameter gear shaft with the Dremel.

I should have said as far as the inner race, all you have to do is weaken it. stubborn little things

If you ever want to cut a bearing off with a Dremel, you don't have to go all the way through the inner race. Once you get halfway through it, support the bearing at the opposite side of your cut, then take a chisel in the cut and rap it with a hammer. It will split the bearing race in half.

GK, Kevin,

Ah, good info. I didn't realize that... thanks!
