Rusty and all,
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)........
FWIW

Rusty,
Chuck Dunlap is currently flying with TES O-rings supplied to him
by Paul Lamar........ These are Creavey seals of the sizes determined
by Paul L.......I failed to ask Chuck the flying hours on these seals.....
Chuck jump in here if you are listening !! I do know that the flying
conditions in Arizonia where he lives put a strain on both coolent
and oil cooling systems and their respective seals.......If there are
others currently flying these seals in the rotors I am not aware of
who they are !!

The Rotor Oil Seal O-ring sizes are: (Credit to Paul Lamar)
PFA-SIL 0.093" section 4.680 inch ID $4.59 each
PFA-SIL 0.118" section 4.330 inch ID $4.47 "
The Coolent O-ring sizes are:
PFA-SIL 0.093" section 11.190 inch ID $8.33 "
PFA-SIL 0.093" section 8.950 inch ID $6.60 "
Hi Kelly,
Thanks for posting the final results of your quest. This will be good info to stash away. If nothing else, these are quite a bit cheaper than the stock rings.
Is anyone currently using the TES o-rings for the oil seals, and have significant time on them?
Cheers,
Rusty
