When reinstalling, there’s a roller cup that goes on the pump’s spring, that rides on the shaft that drives the pump. Is there a correct orientation for the roller cup wrt the shaft?
Yes, the correct orientation is setting the one tooth on the side of cup (it's about the size of a pen's ink tube) in line with the groove in the head. The groove is either straight up or straight down, I cannot recall which direction was correct.
It's straight up, in the 12 o'clock position. Another video showed this. I would also suggest removing the battery and battery box, as it allows much more space to maneuver the wrench, extension and socket in there to remove and re-install the lower bolt.
