How do you punch out the 32-039

It's funny you should ask this, we're actually in the process of making a video on how to remove the 32-039 axle. It's not done yet, but keep an eye out for it in the near future.

In the meantime, I can tell you that it's not too difficult. What I used was a scratch awl like the 75-029, or really any tool with a point on it to push out the axle. With the axle removed you will then need a small flat blade screw driver to pry out the hub from the back side of the roller. The hub should come out with a little effort, exposing a 3/8" diameter hole in the wheel. 

Let me know if you need clarification on any of these steps!
