Does anyone out there have a proven way to remove the threaded locking
ring which secures the electric motor to the lower gear housing on a
prop-pitch motor?  All of the previous P-P's I've had experience with
had the retaining ring secured by peripheral bolts and was obviously
very easy to remove.  This one has a threaded ring which has an ominous
decal nearby on the housing which says "tighten to 250 to 300 foot
lbs.!!  (They must have only had gorillas in the AAF to work on these

I've got a spanner wrench which I believe was recommended in a post a
long time ago, but this doesn't even begin to turn the ring.  Using a
drive punch with a hammer looks like it would destroy the key slots
which obviously I don't want to do.  It seems like the only way to
remove this ring is with the proper tool and a VERY large gorilla!
