Paul,

I'm still studying the best way to go with my PSRU.
and need some information.
What is the planetary gear bearing (plain or needle roller) in the C6/E4OD planet.
Also need to know what the material the sun gear is made of.as I'm considering cutting a spline
into the sun gear centre (as opposed to a shrink fit to the shaft, as I assume most are using).
Any information would be appreciated as these questions come from an Aviation Engineer from the
Sydney University who has offered assistance in the total project.
TIA

Its a needle bearing in the planet gears.
I have no idea on the sun gear material. Could be 4340 or some other chrome
molly alloy. I'll bet it is hardened however. You'll play hell cutting a spline
I would wager.
