So my guess is that the closure procedure would be..
1./ Locate the plug in position, aided by the spring assist.
2./ Use the bolts to hold the Pins into the Tracks.
3./ Tighten each of the 12 Pad Adjusters to a specific torque, to achieve the desired plug sealing force.
4./ Restore all cosmetic trim pieces.
If any Aircraft Technician has the actual Boeing Procedure, we would love to hear from you.
For #1, how do you think the "spring assist" helps locate the plug in position? In fact installation would require pushing down the plug
against the springs, which are working
against alignment of the stops.
For #3, unlikely, as this would mean the plug install would have a different procedure from the E/E door option which cannot be installed with friction between the pads and pins. More likely there is a specified gap which is closed upon pressurization. Also, your step #3 would mean the 12 adjustments would need to be made every time the plug is opened and every time it is closed.
