11. Place the complete assembly on the front housing cover. Before the assembly is pressed on all the way ensure that the connections for the magnetic coil are in the correct position relative to the a/c compressor. and that the three protrusions on the back of the magnetic coil are aligned with the three recesses in the housing cover.






12. Install circlip (5) for assembly
13. Clean friction surfaces of spring plate and clutch body.
14. Rotate the pulley with the clutch body to check whether the pulley is aligned properly. If not, readjust pulley.
