See
General belt adjustment instructions:, page 38
.
Step 2:
Using both hands, gently move the IMF assembly forward toward the front lens
so that you can access the front lens motor.
Step 3:
Using both hands, gently move the rear lens backward so that you can access
the motor.
Step 4:
Loosen, but do not remove, the four front lens motor mounting plate screws so
the motor moves freely.
Step 5:
Turn the pulley back and forth two or three times and allow the spring to take up
the slack in the belt.
Step 6:
Tighten the screws in a star pattern.
Step 7:
Pinch the belt together to ensure it maintains pressure.
Step 8:
Turn the motor by hand counter-clockwise to drive the lens until the IMF closes.
There should be a slight resistance. Continue turning to open the IMF.
Step 9:
Turn the motor by hand clockwise to move the lens back. If the IMF does not
close properly, readjust the front lens belt so that it is tighter.
