Lay the large black hinge bracket flat on the table.
Place the three small shiny friction plates in place in the hinge bracket.
Place the dustcover in place and fit the spring to the hinge bracket at the center with a black plastic holder (with square nut), a screw and a washer.
Don't mind the springs ends at this point - just let them flap around as they please.
The spring has small curves at the ends, that needs to run in the grooves at the ends of the dustcover, so make sure the spring is the right way up, or it will run with the sharp pointed ends in the grooves and damage the grooves.

Then grab one end of the spring with pliers, twist it to upright position andset down the springs length in
the groove in the hinge plate (some hinge brackets have small tags it needs to go around and between) and the groove in the dustcover.
Often the spring will be able to sit by itself like this.
Put a black plastic holder with square nut in place, hold it with a finger or two while you lift up the whole assy and mount the screw and washer from the other side.
Same job at the other end.
Takes a little practice but it's a 2-minute job when you know how.

This is very encouraging, thank you. If I understand correctly I would have to do more disassembly to remove what you call the hinge bracket. I think you mean the back of the deck- really the back side of the whole thing. At present the spring is still attached so maybe it is already held by the friction plates and I don't have to do that part. 

The shiny friction plates are perhaps the stainless steel bits that are angled. I'm not sure what place they go in. If you have the diagram that I referred to for the RX it might be helpful to use part numbers. 

One of my black plastic holders with the square nut is broken. Do you know a source to replace this part? 

This evening I will study your reply further and see if I can follow your directions. 

Kind regards, Joe

The shiny angled pieces goes inside the large black hinge plate, one each end and one center. One for each holder.
They create a small distance from the hinge plate to the dustcover. 

Parts missing? - Ask at Beoparts.

Hello Martin- I assume you are the same Martin with whom I've been emailing off this forum. Thanks for all. Looking forward to doing the reassembly when I get the new holders. Can this be done without taking the back piece off of the deck? Or do I need further disassembly to get started? Your text above seems to indicate that, if I'm understanding correctly. (Maybe I need more than a PhD in engineering to pull this off! ) 

Hello again Martin- for some reason I had trouble navigating back to this thread. My difficulty reduces down to correctly positioning the angle brackets. The diagram looks like they sit between the plastic holders with nuts and the hinge cover. I had them in that way and the cover would not close. So not sure what the picture is supposed to look like. In retrospect should have photographed before taking apart, always a good plan. I took the hinge cover off to work on this and understand that it's necessary to do that. Now it's back together, minus the brackets. I'm hoping I can install one at a time without starting over. 

The three shiny angled metal pieces goes inside the large black plastic hinge cover.
They sits all the way up under the "hangout", one each side and one centered.
If you look closely you can often see where they were fitted previously.

They go in as the first things, - before the dustcover is placed in position.

Martin

What holds them in place? Are they held by the wire springs? Are they in contact with the plastic holders that are secured with the screws? Martin- I've been staring at this a good bit and I don't see it. Is there a photo you could send? Or if I send a photo could you indicate on that photo?

They go here, they are in fact lose, only held in place by the dustcover itself when mounted (- in turn held by the three holding blocks).

Thank you Martin- that made it clear, and all back together now.
