I posted 'Wing off!' some time ago regarding taking the wing off my 2007 +4 4 seater. I had some signs of corrosion creeping up from the beading so it needed treatment.
Putting the wing back was not as straight forward as taking it off as there is a certain amount of spring in the wing and cowl. This causes the fixing holes along the edge of the wing not to line up.
This is the best way that I found to do it.
Place a cloth over the top wing stay and bumper if you have one. The wing stay needs to be secure but not tight on the crossframe top.
Place the wing on the inner wing valence.
At the same time slide the rear into the channel under the door and the front under the cowl.
Loosely fasten the outer bolt at the rear of the front wing that attaches to the rear wing, ensuring the rubber washers are in place.
Press the wing in towards the centre at about halfway between the cowl and the bulkhead.
Press or screw in one of the allen key bolts in this area. I found that pressing the wing in with my chest, while screwing the bolt with one hand on top and securing the nut underneath, was sufficient.
Working forward from the bulkhead, press or screw in the remaining allen key bolts.
At the cowl, there is a small countersunk allen key bolt at the bottom of the cowl in line with the radiator grille screws. Screw this in.
I found that most of these wing screws needed screwing in as the tension continued to pull them slightly out of line.
Screw in the remaining bolts along the cowl starting at the bottom working to the top. There are 3 allen key and one hexagonal, which is in behind gusset on the top of the cowl.
Before tightening all the wing bolts ensure the beading is in position.
All the allen key bolts should have fibre washers between the head and the wing, except those in the cowl. (I think the cowl is steel for strength).
Bolt up the top stay to the sidelight, ensuring the rubber washers and the sleeve is in place between the wing and stay.
At the rear of the wing, attach the inner bolt and tighten both bolts until they are compressing the rubber washers between the front and rear wings
Attach the two lower stays and connect the electrics.
I assembled all the panels using ACF50, which I will now use for 'oiling the beading'. It is good stuff and gets in everywhere.
All fastenings were coated in Duralac insulating paste to inhibit galvanic action.
The beading under the door was sealed with marine adhesive sealant and, when the channel was screwed in, this squeezed out giving a watertight seal. This was not necessary on the cowl as Morgan had glued a rubber insulating strip between the cowl and the beading. There was no sign of corrosion in this area.
Morgan use rivets to attach the beading to the cowl. These stand proud and dig into the wing. I smoothed these with a thin coat of the sealant adhesive to protect the wing.
I am taking off all the wings to do the same work, and will report back my findings.
