[QUOTE="DSheetz, post: 2789564, member: 91783"] Buck; I went to school for steam power and propulsion and yes after a rebuild the first time they come up to speed it is always nerve wracking. bringing them up to temp on turning gear getting the sag out takes time and somebody always wants to rush it, what do you mean I will wipe the seals out.
