Answer
Hi Charles,
There is a little tool, and a trick.
The easiest way is to loosen a couple main caps, let the shaft drop a tiny bit, and push while rotating the shaft. Let the friction of the shaft help you.
A motors manual has a picture of the little tool you can make to stick in the oil hole and rotate the shaft.
