Tracy,
Can you expound on the need to replace the
Hurley seals. I have the 3mm Hurley seals in my 20B, with about 10 hours of ground
running. At the time I was rebuilding my engine Hurley seals were the best
seals to use, or so I was told. So, what’s changed? I also have the TES
o-rings installed throughout.
Thanks,
Mark S.

The tear down and apex
seal replacement job on my 20B turned out to be a 6 day ordeal
instead of a quick 2 hour job but it's done and I can get back to
finishing the RV-8 again. Most of the problems were caused by
inexperience (haven't had to tear down a rotary in over 12 years) and
the fact that this was not a standard 20B but a mongrel built out of mostly 13B
parts. I went ahead and replaced the stock
coolant O-rings with TES parts while replacing the Hurley
apex seals.
