Is it possible to replace just the deadbolt part of a mortise lock? Recently mine has occasionally been over rotating when I try to unlock it. The screws holding it on the inside were loose so I tightened those up but still get it. Doesn't happen every time but enough I don't want to break it by accident. I've changed plenty of deadbolts before but never one of these and wanted to know if it was something easy to fix before I start fiddling with it

Thanks for any help!
