I assume from the subject that it is frozen.
First step is to pull the head and see if you can then rotate the crank.
If it is still stuck, then I soak the bore/rings with a penetrating oil
(chose your favorite) every day for a work week. Try it again the following
weekend. I use a mallet and piece of wood to gently work the pistons.
Just a little though, you want to be careful of the bores. At this point
I have usually removed the crank first. Hold on to the con rod so if the
piston slips out it doesn't crash to the floor.
Although the TR motor does resemble a tractor motor, the same techniques
don't exactly apply. You can put a lot of force on tractor motor parts
but a TR revs a lot higher with a bit tighter tolerances and is therefore
more sensitive to damage. I have seen some pretty brutal techniques
applied to stuck tractor motors. Done a few myself :)
