I got a hold of a scrapped Varian V70 and have been trying to 'nurse' it back into health.
It had a significant quantity of some oil within it when I got it. I drained it all out over a long time, but it still doesn't run right. I can get it to spool up and it sucks good, but after a few moments the controller seems to give up on trying to drive it and shuts down. My conclusion is that there is oil in the bearings, which is slowing it down.
Any thoughts if that sounds about right? And if so, is there a fix? Could throwing some suitable solvent in help? (A spider to catch a fly?)
