and the only other winch i've ever had apart. Mile Marker H10500
Single planetary gear set, thrust bearing in the end
I don't remember the shaft diameter, but it was more than 5/16" as it doesn't have the massive gearing benefit
gears
and i pulled the number off of the hydraulic motor and it came up as a Prince 17.9 Cu In splined motor, which appear to be ~$3-400 for a replacement. but as a 2 bolt with a common spline, wouldn't be particularly difficult to change out to a different sized motor if somebody wanted to mess around with it
i'm not sure there is any difference between the 10500 and the 12000 other than the 17.9 cu in vs the 24 cu in motor, for example

which is why the electrics are generally preferred for speed, because they automagically adjust line speed to load via amp draw to ensure you've always got the highest line speed the load will tolerate, while the hydraulic gives you a static line speed regardless of load.
I don't know what breaks on winches besides motors and solenoids, so robust internals are probably not too much of a concern really
