Once in my physics 1 class, the professor called on me and asked for an answer I totally didn't know. I replied "Who cares, the earth is flat and this is all made up BS anyways." I don't think he knew if I was being serious or not, so he just called on someone else.
Bold move

One for @timg and any other metallurgical experts.
Pins worn, bushes not so by eyecrometer at least. Auto greaser working.
I really enjoy my job on days like this where I get to help with something interesting.

No expert here Adam, but thanks for the comment.
I would tend to think the pin missed it's nitriding process. Was that pin customer built? Nitriding is better than carburizing as you don't want through hardness just surface hardness. Carburized pins will completely fracture in halve. My only suggestion is to add some grease ways into the bronze bushings out from the center. You would need a football burr for non ferrous metal prolly same as what guys on here port saws with. Be sure they add the dirt seals that are missing in the boom front. It will help keep out the abrasives, red zealie dirtzzz.
Morning to the rest of yinzers. Woke up to 4" of snow and still coming down. Have a great Sunday guys. Peace out.

-11 here this morning. Last time I had a procedure done it was cold like this. Seems to be a trend for me. Need surgery well enjoy some cold azz temps. Anywho going to make the best of another day riding the couch like Dallas. Hopefully I’ll be back up quickly.
26 degrees here now
and with the tear you have you may want to plan on surgery for knee replacement so get use to the couch for a little while old man
