Secondary air
Follow these steps to clean the sponge filters of
the secondary air system:
1) Remove the snap-on plastic cover (
1
) on the
transmission cover using a small screwdriver as a
lever on the retaining tongues in order to insert one
of the three slots found on that cap.
2) Wash the polyurethane sponge with water and
soap, dry all components with compressed air and
refit to place. Refit the intake cap respecting the
angle reference.
3) Undo the two fixing screws (
2
) on the aluminium
cover of the secondary air housing in order to
reach the polyurethane sponge inside that hous-
ing; clean as indicated in point 2) and refit all
elements after checking the steel tab is not de-
formed and/or does not guarantee correct tight-
ness at its fitting; replace if necessary.
N.B.
UPON REFITTING, MAKE SURE TO CORRECTLY FIT THE
TAB IN ITS FITTING ON THE TWO PLASTIC AND ALUMI-
NIUM COVERS.
CAUTION
WHILE CARRYING OUT OPERATION 3), ALWAYS CHECK
THE TWO RUBBER COUPLINGS (3) ON ONE END OF THE
SECONDARY AIR PIPE FOR CORRECT TIGHTNESS AND
CONTINUITY; IF NECESSARY, REPLACE THEM AND USE
NEW CLAMPS TO FIX THEM.
