Interpreting Model M transmission guidance

[CLWebster]

From the Model M Instruction Manual, page 8, dealing with adjustment of the long drive belt and the small pulley:

"....The long belt should then ride high in the 4" pulley, allowing the inner faces of the pulley to touch. If there is clearance between the inner faces, loosen the nuts on the clutch rod #1814 at clutch clevis #1818. Screw up on the forward nut while rolling the machine, until the inner faces of the pulley touch."

How would the "inner faces of the pulley" touch? I've asked around and got one answer, but I'd like some input.

Thanks,

The pulley is adjustable ...meaning that it will spread apart allowing the belt to ride down very low in the pulley.  In that position, there will be a wide separation of the pulley near the center shaft.  The pulley can be narrowed causing the belt to ride very high near the outer edge.  That make the single pulley function as if it were both large and small.  To have the correct adjustment, there has to be be a base width measurement taken when the two sides almost touch near the shaft.  These things are widely used on farm equipment for a variable speed drive.  Does this make sense?
