Good approach
Shayne good approach lets you see what is happening while you pull the pin out. I've used as a field expedient a large socket wrench, washer and long bolt with nut. Yours has the advantage of letting you see if the pin is turning as it comes out. Had to do this once in the field with only the socket and bunch of washers and a single bolt using the threads in the pin for pulling power. Problem was that the pin started turning and I could not get the bolt out to put more washers under the head of the bolt, ended up pulling it the rest of the way out by prying under the washers with a pair of screw drivers. Next time I'll use your method.
Or of course you could use Special Tool XA-3363-A Pivot Pin Puller
