If we could do a survey, I bet we would not find ANY unmodified Ross
boxes  with 500 hrs. at 130 HP average output.  I know that there is
not any way to prove this, so you are right in that only time will
tell for sure and we have only heard of a couple of failures - I
wonder how many failures Ross knows about?  Ross's system might work
fine in low HP applications, but ...  We do know that Ford designed
the gears to have internal lubrication, which Tracy implemented and
Ross did not implement.  Ford would not have incurred the
manufacturing overhead for this if they had not felt that it was
required for durability.  We do seem to hear about a lot of boxes
that have gone back to Ross for rework - why?  I'm not trying to be
difficult; I do believe that this box has a potential for major
problems based on input from the members of this newsletter.
