    • Had an issue with this lens where it would retract after zooming and there was a rattling from inside the lens so I decided to take it apart

    • First step as with all canon EF style lenses is to remove the 2 screws holding the terminals to the lens then remove the 4 screws holding the outer ring to the lens.

    • Once these 6 screws are removed gently remove the inner ring from the outer to free the terminals.

    • Next pull up on the plastic outer of the lens, no screws need to be removed to allow this just give it a little jiggle.

    • Gently unplug all of the ribbon cables except the 2 plugged into the brown and beige connector you will need to gently pop them open first before you can remove them.

    • Remove the one screw holding the PCB board to the lens and set it to the side.

    • Remove the rubber band that goes along the front of the lens. under it is this black square that looks like electrical tape, remove it.

    • Now unscrew and set this to the side. I believe its some sort of position sensor and we are removing it to avoid damaging it.

    • During my disassembly these 2 tiny screws appeared along with this metal bar. Turns put this was the cause of my issues. I found where it belongs and screwed it back in.

    • Assembly is these steps but backwards. Be sure when reassembling the lens housing make sure to line up the black rod with the 2 prong silver fork or your zoom will no longer work.

Conclusion

To reassemble your device, follow these instructions in reverse order. Be sure to line up the black rod with the 2 prong silver fork when putting the lens back with the housing.
