My interconnect cable wasn't glued hard, but was attached via adhesive which took careful effort to peel away. I had to remove the screws on the board to get to the lower level to clean up coffee, though fortunately there was very little. However when I went to reassemble, I found a free spring and no clue where it came from. Thankfully, enlarging the third picture in step 5 shows where the spring is under the wheel assembly and I was able to reassemble successfully (also the two screws holding the wheel assembly are slightly longer than all others). I even managed to reinsert and restick the interconnect cable correctly.
