With all due respect, you shouldn't have to destroy the outer bearing to get it off the spindle. It should come off with a bearing puller or a press. The crush sleeves are, as has been stated, throw-away. However, you might want to replace the bearing with a new one once it's off anyway, just because it's such a PITA to remove.
When I did this a few years ago, I found the bearings and crush sleeves at a shop in northern Phoenix, Delta Motorsports. 602-265-8026.
Once assembled, you torque the assembly to about 5 inch-pounds of torque at the shaft. I used a spring scale hooked to one of the flange bolt holes. The manual I used said not to overtorque the adjustment, as it will then over-crush the sleeve and lead to an incorrect adjustment.
This is a link to the thread that was ongoing when I went through the process:

Hope this helps.
