No pictures with this copy, but I saw them on another. The input (sun) shaft
looks shorter too.  Our units are about 14 inches from engine flange to the
prop hub face.

Everyone says the new thrust bearings do not get enough oil.  I have ground
4 small half moon craters inside the thrust washers to let oil pass on the
inner dia.  Be careful not to go into the roller track area.  I have .060"
washers on each side of one new trust bearing.  We redesigned the Hat to
make it a bit stiffer.  Counter bored the recess for the Allen head bolts.
The 2.600" lip inside the hat holds it in the center of the planet carrier.
it should just fit, not press fit.

If the engine and bell housing are not aligned from Ross, we could get
primary shaft wobble that could destroy the thrust bearing.

I have two drains, One on the 90 degree side, and one on the 180, bottom. I
could add a oil inlet to the 90 degree tube with restriction. And get more
oil to the planet system.  Do you think this is important?

Everyone complains about blowing the rear seal.  And no one complains about
the front near the prop hub.  Logic says the pressure behind the sun gear
towards the back seal gets higher than we expect.  I added a drain from the
back side of the bell housing near the seal to the pan.  this should get oil
flow.
