I went for the O200 crank STC when I had my engine rebuilt about 200
hours ago. I don't regret it, even though my crank came back yellow
tagged at .010 under. I sold my crank for $1000 which recovered half
the cost of the O200 crank. Since my engine was a C75 before, I cannot
judge the power difference, but with a 7150 prop I can cruise easily
at 107 and I have never had any climb problems.

A good friend rebuilt his C85 using the O-200 crank and rods. May
also need the pistons, I'm not sure. While doing this he opted for
Millennium cylinders. He's owned the plane for over 30 years,
taking it through many overhauls and rebuilds. He did not believe
the upgrade in performance after the rebuild.
I say go for it, even if your crank comes back good. It should be
worth a few bucks.

Subject: [ercoupe-tech] Overhauls and O-200 Cranks
One last question as my engine trucks off for an overhaul tomorrow.
Have any of you opted for the O-200 crankshaft STC on the C-85?
My current crank is an ECI .020 STC which is the maximum turn down.
The
engine has about 900 hours SMOH in the early 1980's; bottom was redone
about 500 hours ago (1997) with the ECI .020 crank and bearings (well
documented).
If the .020 crank comes back from inspection still meeting tolerances
any long-term disadvantages for keeping it in the bottom? Would I be
better off finding a yellow tagged .010 C-85 crank? Would upgrading to
an O-200 crank STC be better long-term?
Many thanks,
