Another method that has worked for me
Hi Gary
I hear what the guys are saying about heating etc. But lets get back to the three holes and how the manual says to tap out the bearing. Here is the trick I have used with success.
1. Take a punch that will slip down through the three holes easily. Not a tight fit just in case the head mushrooms you want to be able to pull it out. Make a punch head for your air chisel, find a piece of tubing to hold your punch square on the punch head of the air chisel.
2. Vibrate the bearing using punch and the air chisel, keep working around the three holes. Don't really lean on it you just want to vibrate it at first. After you have vibrated each point a couple of times then you can increase the pressure.
Keep an eye on how far your punch is going it so that you don't end up cocking the bearing race.
This approach has worked every time for me.
Heating the bearing race may actually be counter productive because it will make the race expand hard against the hub. Though heating and letting it cool may help. Think this is what makes the welding bead trick work. Or if you can heat the whole assembly and then cool just the bearing race that may let you tap it out.
Let us know what works.
Cheers Phil
