When I did it on my TR3A, I pounded one of the old lower inserts flat and
used it as a drift to start the upper inserts out. Of course you have to
pay attention, they only come out one way. But once they are out by 1/4" or
so, I was able to pinch the locating tab against the crank journal with my
thumb, and rotate the crank to pull the bearing out.
Another trick I've read of is to bend a cotter pin to stuff in the oil hole.
But I have no idea if it's possible on a TR250 motor.
