Paul  I am rebuilding my redrive and Tracey sent me the parts with two
thrust bearings and I thought one went on each side of sun gear do both
go towards the plate and none towards the planitary carrier just a steel
washer ?
Thanks for all the work you do with this news letter  Keith building

Both go towards the plate. When holding the PSRU prop flange down you should
have about .030" up and down travel on the sun gear. Use a straight
edge across the rear spacer to check that. Here are some pictures.
Some C. Smith just sent me.

Some times the sun gear needs a bit of machining to get enough clearance.
If that is the case take a picture and send it. I needed mine done so my
machinist friend Jim Poole can do it fairly cheaply as he just did it for me.
