Finn,
Does your Ross gear box look like this?
You never know.

If so perhaps you could put a 1/2 AL plate in front
of the seal between part 3 and part 11 to take the
thrust bearing load and make a new 1/2 inch longer shaft.
You would also need longer studs or bolts to hold
the whole thing together.

A good idea if I needed a new shaft anyway. One problem is it leaves very
little space for the thrust bearing and pin, only 13mm (unless I counterbore
into the plate). The thrust bearing Tracy is using is 12 mm thick, leaving no
space for the pin. I wish I knew how thin that pin can be and minimum edge
distance from pin to planet gear teeth and from pin to thrust bearing. I'd
also like to know how much force the bearing applies to the plate (how thin I
can make it).

The plate can be as thick as needed and counter bored.
I am sure all the torque is not transmitted by that pin alone. I think
the gear is welded to the shaft.
