To reassemble proceed in opposite order. When positioning the plastic caps at the very end, note that they are not just flat discs, but need to be glued on in a specific rotational position.

Carefully move the head up and down a couple of times after reassembly to move the wires into their correct positions under the plastic cover. If you encounter significant resistance, you may have to disassemble again and check for the correct positioning of the wires.

Good luck!
