Question.

What is the current thinking on the modifications required to
successfully operate a Ross PSRU, specifically the 2.17:1 version.  I
have a older one (7-8 yrs old) that is bolted to a '87 6 port.
Unfortunately, the project has stalled and the engine/plane has not
flown yet. (nor will it for awhile).  Fortunately, I ought to be able to
take advantage of the experience of others with time in the air and on
the ground.

I have used loctite to prevent motion of the carrier unit as per Tracy
Crook's recommendation.

What other areas do I need to address. Specifically,

1. Input shaft thrust bearing.  Has anyone had  Ross retrofit a thrust
bearing?  Is their solution the best or is there a better way to do
this?

2.  Several people have mentioned a higher than desired oil temperature
rise in the PSRU oil. What are the recommended solutions. Does this
indicate a need to provide cooler oil to the unit or is it that splash
lubrication is insufficient and a spray bar sytem needs to be designed?

3. What other problems don't I know about?

Thanks for the help.
