Thanks, it's pretty clean! It wasn't easy without the tool, that is for sure. Echoshawn gave me a tip, I used a c clamp with a small socket to push it through and a bigger socket on the back side that the pin could go through. Definitely redneckery. It was just as hard getting the new one back in. Sounds easy enough but it's tough to get the sockets to stay put where you want.
Nate and Echoshawn, if possible I'd appreciate seeing some pics of the device you created to remove the wrist pin. I'm all about Redneckery when needed, and it sounds like you have a good process in use. Fine looking Poulan 4000 by the way. I love those 4000's and would have a ton more if I could find them. My favorite one has a chain brake that my oldest uses sometimes. I just flat out love 'em! Take care, Max.
