To wrench, the Electra is a Babe!!! I loved working on them. If you do not stay on top of them they will run away reliability wise and cause you much pain and suffering. You MUST get a survey done by by someone who knows these machines intimately or you will have problems. Due to the age of the components etc you will have many " Why the F^&ck is it doing that"? moments. They are not fire and forgets and need to be looked after 100% or the operation will suffer. You will need very good engineering staff and lots of spares.
