The 4014 has a chain drive to the lubricator. In older pics, the chain in contained in a metal enclosure, guessing mimicking some bicycles back in the day who had their chains sealed up and in an oil bath.
No, no "oil bath". Simply z sheet-metal cover over the chain assembly.
But now it is out in the open, and when I observed it running, noted quite a bit of slack in the chain.
When 4014 was first returned to service, the steam crew had not had enough time to fabricate new covers for the lubricator chain drives. You might check more recent photos of 4014.
Does it ever jump the sprockets?
No, as there really is not that much movement.
Check-out page 53, in the book "Big Boy", by William Kratville (Copyright, 2004), there is a nice close-up photo of the cover over the chain drive.
