Jim,
The correct tool to use on the drain plug is a 7/16" square socket (8 internal
points instead of the usual 6 or 12). I have a Craftsman threesome of these,
in 3/8, 7/16, and 1/2, that came as part of a large socket set I bought many
years ago. I don't know if you can buy them separately, but I would suspect
so. The good news is the drain plugs for oil, tranny, and diff all use the
same plug. So, buy a bunch of them (they're cheap).
One other tip -- put a couple of wraps of Teflon tape on the threads before
reinstalling. You'll need a lot less torque to install them to seal, and
they'll be a whole lot easier to remove the next time!

But, the oil plug was another issue. Go kart racing sold us on magnetic oil
plugs (makes a huge difference when you don't have a filter), so we had one
ready to put in during the oil change. First problem was getting the old
plug out. 3/8 and 11MM were not really the right size wrenches. Adjustable
wrench (I thought last resort) wouldn't grip it. You guessed it, vise grips
to get the drain plug out. A conservative guess would be about 60 ft lbs of
torque on the plug. The plug appeared to be a tapered 1/4" (guess) pipe
thread plug. The magnetic plug we had ready to put back in (nice face with
a copper crush washer) wouldn't even go in those threads. So we put the
pipe plug back in.
Anybody else run into something like this? Any idea what those threads
really are?
