All this talk of repairing con-rods is silly. Make new ones, if you
must.

BUT! My real question is this: What sort of situation would have
someone tipping over and allowing to fall a compressor WHILE IT WAS
FRIGGIN' RUNNING?

There is no way that could have damaged the con-rods if it were off.
So...
What the HELL did you do? (And maybe WHY would be a good one, too.)

Actually , I was backing a load of lumber in and the end of a 2x4 12 feet
long pushed it over . I was watching the other side to be sure I didn't back
into one of the legs of the carport that's now my shop space . Compressor
wasn't running , wasn't even hooked up . It landed on the pulley , pushed
the crank bearings out and snapped both rods . eBay has 'em for 22 bucks
each , and I shoulda repaired it then ...
The point has been rendered moot . I tore the new unit down , discovered
that the top 2 rings on both pistons appear to have been installed upside
down . Bottom edge of both was shiny , top edge has never touched the
cylinder wall . No wonder there was blowby ! So I did a light hone on both
cylinders and turned the rings over , seems to have solved the problem . But
next trip to Memphis I'm bringing the other pump up for parts to repair the
one with busted rods .
