Step 9.
Replace damaged iris leaves and nylon washers. Undamaged
leaves and washers can be reused during replacement.
Note: Install a new belt or re-install the belt clamp in the same position on
old belt. Clamp ruins some of the belt’s teeth and will cause problems if
clamp is not re-installed in the same position.
Step 10.
Re-assemble iris assembly by doing Steps 2 thru 7 in reverse.
a. Right-hand iris leaves are installed on standoffs 1, 2, 3, and
4 nub side up and in fully opened position.
b. Left-hand iris leaves are installed on standoffs 5, 6, 7, and 8
nub side down and in fully opened position. Nubs fit in
holes in actuator ring.
