B. Insert a socket wrench into the square hole in the
idler arm and rotate the wrench upward (
Figure
54 ).
Important:
Do not rotate the wrench upward
too far because damage to the idler arm
extension spring may occur.
4. Measure the spring from inside loop to inside loop;
refer to
Figure 56 . If the spring stretches to more than
8.9 cm (3.5 inches), replace the spring.

5. To increase the spring tension thus increasing the belt
tension, shorten the eye-bolt height by loosening the
top eye bolt nut and tightening the lower nut (
Figure
55 and Figure 56 ).
