My prop should be back at the end of this week, so I'm very reluctant of
taking the first step of pressing the old sun gear off. As it is right
now, I could put everything back together and go fly.

Concerning lubrication, as far as I can figure, the oil that lubricates
the prop shaft bearings returns through the prop shaft. If I drill a hole
down through the center of the input shaft (from the front side) and a
couple of small holes in through the sun gear, some of that oil should
seep out and help lubricate the gears.

Finn please don't do this. The spalling input gear is giving you an

it's problem!

As to the oil returning through the prop shaft? That sounds unlikely. Can
you post a diagram of this.

Jet engines use holes in the shafts as air/oil separators, with centrifugall
(or petal??) force slinging the oil back out as the less massive air flows
through into the shaft.

Finn don't be so cheap. Go buy a new sun gear. Heck buy one from Tracy.
He's got a bunch.
