I agree with mike about the problem that i had with my TES
o-rings. Let me restate the situation that i had. I was one
of the first people who used the TES rings and the rings
that i used were from paul lamar.these rings were used in the
rebuild of my 13B
that i was rebuilding for my CAR that was purchased for the
reason of obtaining some rotary engine experiance. i have
rebuilt other engines but never worked on or had any rotary
engine experiance at all.I felt that it was nessary to gain
as much experiance as i could with the rotary prior to using
it in an aircraft.Soon after i obtained this car it started
to smoke very bad, it was smoking a little bit when i got
it.i had only driven it about 50 miles total.It did not
bother me about that as the reason i got it was to get some
experiance with it,but i would have liked to got some more
operating time with it first.After pulling the engine and
during the tear down i discovered that the oil control
o-rings were almost completly disintegrated on the rear
rotor.I was nor able to work on the engine as much as i
wanted to due to other
things that nedded my attention plus som medical problems
that i was working thru.
As i had never put one of these engines together i had no
idea what to expect when i was torqueing the tension bolts as
per the shop manual. After the tension bolts were torqued
down their seemed to be a very small gap between the rotor
housings and both end housings. I did not feel that this was
correct as i could insert a thin blade of
my feeler gauge past the edge of the iron housing and in
between the rotor housing
part of the way around the engine.I Talked to Ed Anderson
about this and he checked his engine to be sure that the
iron housing and the rotor housing did indeed
have no clearence between them when the engine was put
together.As i thought and ED confirmed ( thanks ED) their
should be no space where i had one.So the investigation into
the cause was started. This was before the engine was reinstalled.
Afer removing the oil pan i saw a small loop of the
silocone sticking out where a small section of cast iron had
broken out. all i could see was the loop of silocone.
After the tension bolts were taken out and the engine
opened up i was able to see the other side housing damage
where it had pushed into the water jacket. This was the photo
that i sent to you. I have some other pictures if any one is
interested in
seeing these please let me know.The O-ring grouves were
cleaned very well prior
the the first assembly. The sectional size of the o-ring
that was first installed had to have been too large and
caused trememdous pressure to have extruded the silocone out
of the stiffer teflon part of the ring and done the damage
that it did.I still believe that the idea of the TES o-rings
is a good one and i am using the ones Paul Lamar
sent to me ( part number unknown) in the inner coolent
o-ring position as it seems
to be ok . Thanks Tom Kimsey 478-922-1428 kimseyco@aol.com
If you still have that outer O-ring Tom please measure it for me.
