2. Route secondary drive belt (D) from housing around outside of idler sheave (C), and secondary (lower) drive sheave (E).
3. Locate secondary belt tensioning spring.
4. Hook either end of the spring (F) over bolt (G) at the right side of the frame, and the other end into the slotted hole (H) in the tensioning arm.
Picture Note: Upper drive components not shown.
5. Pull tensioning arm back toward frame and route secondary drive belt (E) to the inside of tensioning sheave (I).
