It is probably reasonably quick to change gearboxes/motors over if your using VP's. However because 775pro's are such a precious resource this season, with the supply issues it can't exactly be practical to be going through them at that rate

Have you had any issues with the carrier plates of the gearbox or any other issues with them?
The load rating data sheet, says that the big reduction(7,9,10:1) carrier plates says that they can withstand up to 100 N-m, so your not to close to that, but there are a lot of different stresses in a drivetrain. I suppose part of the reasoning for having the sprocket reduction after the planetary reduction stage was to reduce the torque on the gearbox?

Also how often do you grease the gearboxes?
