One of the dumbest engineered things I have ever seen was in th late 70's we had a new Barko articulated log loader delivered to the woodyard. They just unloaded and hauled ass. Within a hour it blew a hose inside the framing, no way to get to the hose end. We called a couple of company mechanics and there was no access. So they took a torch and cut a 8" hole in the new machine frame just to change a hose.
