I've run across a series of YouTube videos that detail a bit more about rod line pump jacks. The first one involves showing the operation of the engine and belt system that operates the rod lines.
This next one shows the band-wheel and eccentric gears for operating the numerous rod lines.
Multiple rod lines and associated other elements for those rod lines.
Rod lines and pumps are part of this one. There are even rod lines running through trees.
This one has a Tulsa built "underpull" pump jack.
