I am of the opinion (yet to be proven ) that
the use of TES seals in the
rotors may raise the critical temp for oil.......It is well known that the
13B
is most efficient with oil temps in the 160 to 200 F range and that
power
suffers above these numbers........I do not advocate flying with oil
temps
above those numbers but most of us will struggle with oil temps as we
sort out our oil cooling systems.........My hope is that the TES seals
will
provide a safety buffer for oil temp by preventing the rotor oil seals
from
going away with short periods of over temp during test flying......The
same can be said for the inner coolent seal as well with the outer
seal
probably not a real problem (but they are less expensive than
stock)........
Hi
Kelly,
I can't fault
any of the above logic. When this discussion first came up, I
was thinking only of the coolant o-rings, and never once considered that
TES could be used for the oil seals. Assuming they work as well as they
should, I agree that it might help some to use
them.
I can't find
the message now, but I believe Lynn or Leon told us that the first failure
from overheating the oil would be the soft material on the
bearings. Can someone confirm this? What is the first thing to
fail when the oil temp gets too high?
Cheers,
Rusty (RV-3
