More belts to accessories .....
plus more stuff.
Maybe a "well" designed one would work, but they all are under worrisome watch full eyes .
The key word would be a well -"designed one."-
With as much effort to replace ( and EXPENSE ) it might as well be tossed.
A new one is 3500 bucks , and now back to Sq one to repeat all the above *(if you live through it)*
So, why repeat the same mistakes over and over.
I think thats the definition of stupid ?... or crazy ! ?
I would think a well designed planetary would mean check the oil once in awhile and be done.

I mean a shaft which has 2 bearings and 2 gears. A nice large diameter hollow shaft is about as reliable as you can get for power transmission.

A planetary gear set has 3 or so shafts inside it which the planets rotate on. These shafts are smaller and you can't easily inspect them and I am not sure what kind of bearing they might have on them, if any. You hold those shafts stationary and turn the sun and you get a big reduction between the sun and ring gear.
