Got my new conversion C drive from Tracy
today. Looks great, will start working soon to put it and prop on the
aircraft.
However, after close examination of the drive, I
wish to state that it turns out the RING gear IS Fixed on the 2.85. The
propeller shaft is driven by the planetary gear housing (which now rotates)
which is driven (of course ) by the SUN gear. This arrangement
is the opposite of the 2.14 where the ring gear rotates and drives the prop
shaft and the planetary is fixed. The Sun gear drives the planetary
in both cases.
Someone took issue with my earlier speculation that
this was the case with the C drive and not being a gear box guy I declined to
argue the point. However, in this case, it turns out after
rotating the prop shaft it was clear what internal parts rotated
and which did not. The ring gear does not and the planetary does (on
the C drive).
