Paul,

Is it feasible to use a solid case, instead of a split case using inside
snap rings to separate the rotating elements?

milo

In theory yes because the rear flange is bolted on.

But given what I little I know about overhauling
piston engines bearing shells halves are a bit over size so when you torque
the case bolts... the shells compressed slightly and  are held securely
in place.

All you piston engine guys out there chime in on this.

The other problem is the oil slinger near the front of the shaft
but there is a work around for that.

----------------------------------------------
Forgive me for my lack of attention to this, but is someone planning on
fabricating a kit or an entire psru that will provide oil pressure to a CS
hub?  If so, are there any plans on a governor, and what are they?  I would
be interested in a CS psru, seems Mistral is gone to never never
land......I
don't think anyone makes one, that outfit in Canada with the spur gear
drive
did for some time, but seems to have faded.....

Yes. That is what Milo is up to :)
You will have to drive the gov with a cog belt off the nose
of the e-shaft.

I seem to recall Continental cs engines had more problems with leak down at
the 'transfer collar' due to their inherent design.  Lycomings did not seem
to suffer this as much.  I also think I remember the bearing shells are
tanged to keep them in place, and keep the transfer holes lined up.  There
are tests to determine when these bearings and the crank have worn too much
to keep the pressure transferred constant.....of course all these engines
are split case engines......guess that's just the way it's been done to
date.  I suppose you could make it work in a solid case somehow......

Bearing tangs only purpose is to insure that the shell is placed
properly.  Once the shells are clamped with the case, the tangs serve no
purpose.
