I have used the import 10 ton porta power 6 times with heat and round bar to remove the pin, working solo. Harbor freight tools-$125 for the kit on sale. The only way it worked for me was to line the pin up with the hitch or a bolt head on the rear as the jacking point and have your jack and pin aligned straight, otherwise it will jump out of place. Once everything is ready, i started with a short piece of bar on the jack end, because that is all that fits. After heating enough to move it halfway, then i had to switch to a longer piece of bar to push it thru. C-clamps help keep the link from spreading. If it spreads too much, your shoe bolt holes won't line up and you'll have to reheat and straighten it. The pin won't budge with 10 ton without heat. If you find a way to jack it without heat please post it Pete. I think the JD press tool is 50 tons and looks like it hooks the back of the link to prevent spreading. Wish i could watch someone hammer one out and see how it went. I had no luck, but didn't have a 16# hammer. Tried hammering it with the fabricated tool shown in the shop manual. Someone else posted using the hammer method using railroad ties to align the driver. I think wear maybe a factor in how hard it is to get it out.
