Dennis,
The nut was tight - but the 27 mm socket did the trick. Had to mess with
it quite a bit - the shoulders on the nut are rounded t the factory -
but it came off. Using the 3/8 inch internal pipe wrench worked like a
champ to remove the pipe. Once removed -- it was easy access to the old
seal and the installation of the new one.
Just so everyone knows - the back side of the oil cooler has a groove to
hold the new o-ring seal - AND it has pins so that the little loops on
the new seal can be snapped on to them to hold the seal in place while
the cooler is reinstalled. I noted that the side of the case where the
cooler mounts is perfectly flat - no ring groove. The cooler, when the
retaining nut is tightened on the pipe - squeezes down and seals on that
flat surface so it's important it be clean with no grit or debris.
The seal that failed in mine was hard as rocks. Extremely brittle with
age and use - prol'ly the original from the factory. The break in the
seal was clearly seen. There had been an oil weep for a while - the seal
may have been it about to let go completely - when I started one of
these cold mornings at about 15 degrees. I figure that cold oil - being
20-50 wt about did that old seal in.
All is well now.
On to the next project!!

If you really want to get anal - it is part number 068-115-723, oil cooler nut, 27 mm. For those of you w/o Metric wrenches (sorry, sockets) that's just a hair [.00040") bigger that a 1 1/16 inch. Might be a bit tight, and I have used 1 1/8 socket (as well as that Channel Lock mentioned earlier).
