A bolt press is what it sounds like. It presses the studs into the hub unit (idk why we call studs bolts). I think we, as a company, knew about it before the news broke. We had to re-configure the line to add a machine that wasn’t there originally and now we need to changeover between the bolt-type and bolt-less. This changeover is more involved than you might think since some of the components were redesigned for the bolt-type, necessitating some new tooling.
