Re: TR250/6 oil pressure switch

Its been awhile, but I seem to remember a small nut
like fitting next to the threaded part.  I was careful
to soak it with "liquid wrench" for 2 days before
pulling it out, then used 2 wrenches, one on each side
in order to limit the shear forces.  These things always
make me nervous... mine came out easily.

You might try vice-grips in each direction, but its
usually a one shot deal.  Clean around it and hopefully
you'll find the "nut" portion.  

Good luck.
