7. Install the curved washer and the rotor-pulley
bolt and tighten them securely (

Note:
The concave side of the curved washer
goes against the outside of the pulley.
8. Install the brake spring onto the idler arm ( Figure
27 ).
9. Install the drive-belt cover with the bolts that you
removed in step
