Broken tension bolt. Perry had the 35 pound flywheel in there which did
not even slow down. Just bent the bolt over at 90 degrees when it came out of
the hole and contacted the flywheel. Could have seized the engine if it had >been an auto transmission flex plate. Best to drill the headsof those bolts >and safety wire them.

Paul,
If I recall correctly, Tracy Crook stated (in a distant posting) this as a benefit of his "open bellhousing" psru, i.e. to facilitate inspection of the flywheel and related items contained within the bellhousing.  Having "been there, done that" do you feel this problem would have been easier to detect and remedy using the Real World Solutions psru?

Yes. Thanks for mentioning that Mark. Perry had designed the lower cowl so that
it was difficult to remove and inspect that area of the engine. He is now fully
aware and will redesign the cowl.
