Hi Kelly,
Thanks for the reply. So how is it
that you know that TES O rings will
quote:
"take more heat
and pressure" unquote.
What sort of heat?? What sort of
pressure?? How do you know. Who told you??
Has anybody really done some scientific
testing where they have got two identical motors side by side, run them
dry, and the compared the damage. As I said previously, give
your Wankel a decent "cook" and you warp the rotor housings. They
are then "thow-aways".
I'm also curious as to just when and why would
you be considering rebuilding your engine (so you can re-use the TES O
rings). seeing that if an engine rebuild is done peroperly in the first
place, they seem to last for up to 20 years and 500,000 km if looked after
(regular oil changes, clean coolant with corrosion inhibitor, and a
well maintained air filter).
There are basically only three things that will
kill a rotary:
1. Serious Overheating (loss of
coolant, drop a fan belt, water pump failure etc)
2. Running LOW or right out of oil
(blown oil hose, filter cannister etc or just plain carelessness of the
operator)
3. Swallowing something solid and
obdurate (like a nut or a washer or a rock), or being fed dusty
air (if you are silly enough not to run an aircleaner).
I'd be interested on your take. Anyone else
with some experience based reasons ??
Cheers,
Leon

rings vs TES O rings
Leon and all,
For my part I just like the fact
that the TES seals will take more heat
and pressure and reportedly are reusable if
undamaged.........Anything
I can do economically to upgrade my 13B to extend its life for use
at
power levels (75 to 100 percent) it was not probably not designed
for
I am willing to do........After all it is our butts we are putting in
these
airplanes........IMHO.........That being said I do appreciate the
opinions
of all in the group !!

Hey Guys,
Enough already! I'm with Dave on this TES
O ring business, but I'm even MORE radical ...
If the factory O rings were good
enough to win Le Mans 24 Hr, it would seem that they SHOULD be good
enough for our purposes. Moreover, they seem to last 20 odd
years and over 500,000 km in cars that are well looked after and serviced
regularly and the cooling systems kept clean.
The only time I've EVER seen Factory O
rings fail (since the mid '70s) is if the engine has been
"cooked", (and then the rotor housings are warped), or the rotor
housings have corroded (due to lack of a regular coolant changes),
and in both these failure modes, the rotor housings are
throw-aways anyhow. Not the O ring's fault that the engine leaks water
- OIF (Operator Induced Failure).
So seriously, can someone PLEASE tell me
WHY you all want to use TES O rings instead of the factory ones?? Apart
from price, (which seems to be an issue with some), and the fact
that the big bearded guy at that "other" place says you should - so why
don't you guys just ask HIM for the relevant part # - he knows EVERYTHING).
Still, for the life of me, I
just can't see what technical advantages there are (apart from busting
the O ring grooves if you happen to get the sizing wrong). I'm afraid
that it has totally escaped me.
Cheers,
Leon
