[AT] Anyone heard from Bo Hinch?

Tue Jan 24 09:49:12 PST 2017

Cecil I'm really stepping out on a limb here but I want to
say there is a diaphragm somewhere in the system that goes bad
and creates that problem.  My guess is the problem is on the air end
of the compressor not the governor.  I may be wrong.  Like I said, I never
worked on them myself.  Occasionally when they started acting up on
the job the guys would attach a wire to the lever that that rod attaches to
and pull the rod back a bit (towards the air end) to make it run until it 
could
be fixed.  I can't tell you how to do that either particularly on a Detroit.

Hang on a bit and maybe Bo will set us both straight.  I'm pretty sure he 
knows.

OK, that confirms what I was thinking.  It has been 20 years since I set
he rack on a Detroit.  luckily I still have all my old books, just have
to dig them out...   They are buried in some file cabinets behind a
stack of plywood!! That plywood is not on pallets either!!  I think the
problem is the rod from the compressor regulator is a little too long
for cold weather operation...   My problem is that I work with 4cycle
diesels all the time and a Detroit sounds so much different, that  I
have a problem setting the idle speed by ear.   I love Detroits, they
are about the most reliable engine around.

Thanks

Cecil
