The pin on the rock crusher ( paulverizer) on our excavator is stuck we are trying to take it off to put the bucket back on. It will take grease an you can spin the pin around with a pipe wrench and you can hit it out about a inch on rather side but after that it won't come out any further. We tried heating it with a tourch and that helped us to get it moveing a little. I'm open for any ideas
Good day Its a guess but has the pin worn a step in the shaft often wriggling the attachment can free up the pin. Kind regards Uffex
