Replacing gear seal on Gear Products swing drive

Model 105-00004-2 to be exact. This is on a '79 era Snorkel TB50 lift. I'm looking at the cross-section diagram of the swing drive trying to figure out the shortest route to replacing the seal. There's a circle of capscrews holding the bottom-most section of the drive on, and in that section is the bearings and the seal. The output shaft/gear has a castell nut on it but I can't tell if removing those capscrews will let the bottom-most section fall out and give me access to the nut, or if I have to get to the nut from the top (meaning I have to take the whole thing apart). Anybody have experience on one of these?
