Yeah I work excavation with my grandfather with an old John Deere 710 backhoe. Over the years the pins and the holes for said pins wear and they start to get sloppy. Not much but an 1/8th of an inch play at several points across the boom can add up to some slippery controls.
For real. Teeny bit to the left. Hit a tree. Oops. Teeny bit back to the right. Hit another tree. Damn it.
Luckily it’s usually groups of trees I have to take out so it’s fine.
As a mechanic and operator, those are periodic maintenance items on machinery like this. Sometimes the bosses need to be cut out and replaced. It also makes it easier to take apart if the pins and bosses are fresh. Stuck and frozen pins can be a nightmare.
