The tensioner pulleys aren't supposed to be constantly spring-loaded against the belt. Also, E-13 is a shoulder bolt, it acts as a pivot even when it's tightened down. If E-13 prevents the lever #13 from moving, then something's wrong.

#24 is the tensioner bolt, it clamps the pulleys into position. The procedure is to allow the springs to hold the pulleys against the belt, then clamp down on the tensioner bolt. Then the pulleys are locked into the correct position and the springs aren't really doing anything until the next time you go thru the tension adjustment procedure.
