Im sorry if this has been a topic of discussion or im in the wrong place. Im new to this (forum and equipment). I recently picked up a john deere jd400 backhoe loader. The thing runs awesome and aside from some fluid changes and needing a set of tires ive not had any issues. Until last night. It needed new pins in the backhoe bucket and linkage but just like any dumbass who knows better I have been using it anyway. "ill fix it later" Well last night i broke not only a pin but one of the links on the bucket. at first glance i figured no big deal ill weld it up and good as new and throw a new pin in it. that is until i really looked and theyre made out of cast iron from the looks of it. Im told thats an obsolete part. Is there a place to buy aftermarket links? Would machining a new set of links be ok? out of some abrasion resistant plate or something? Also the pins albeit not super expensive if im gonna go the route of machining new links might as well make the pins too. I have access to a machine shop so the work isnt an issue. not knowing what materials to use is. any help would be great.
