 Ken &Paul,
 I would have to support that one hundred percent.
 The hard shoulder bolts are needed to maintain the free-play of the
planets
 in the planetary housing - straight through bolts would IMHO distort
the
 housing.

   You would have to make them shoulder bolts for sure, I am thinking
more on the line of making an inner race/bushing with a bolt through
it so that you could tension against the housing and anchor it to the
flange, also thinking of a steel ring for the bolts to go through to
distribute the pressure evenly so as not to distort the housing.

I don't think you would distort the six pinion cast iron version Ken.

Ken,
Paul may well be right, but I like your proposal - the only problem  I have
with that is the size of the bolt thickness is reduced.
There is another problem (small one), I can't for the life of me work out
how to remove the rolled spring steel pins - their deadended and placed at
an angle. I can only assume to stop them coming out with centrifugal force.
It's pinned only one end.

There must be an easy way or a tool to do the job, the pin is very small
with a 1.5mm centre hole - if you could find something that could go through
the pin and catch (hook) onto the back of it, I believe it would pull out
easily.

Mate if you find a way will you let me know!!

BTW did I tell you that the overdrive is 2.45 - but only 4 planets.
