Figure 2
If the rivet hole is found to be standard dimensions (diagram A) then fit a replacement standard rivet.
On vehicles where the rivet hole is found to be oversize, that is the counter bore dimension has been
drilled all the way through leaving no counter bore (diagram C) , then a new larger counter bore has to
be drilled , 5.Smm , to produce diagram Band the larger rivet used.

and lock into the casting. This rivet hole requires inspection and if found to be oversize the attached
rectification measure performed

Check
If the vehicle is not already listed as repaired in the "Repair history" (in Elsa pro), check for the
campaign identification mark, white spot adjacent to rivet (see Figure 9), should neither be evident
carry out the required work in accordance with these instructions

Genuine parts
The standard rivet for use where the hole dimensions is found to be correct is 3.2mm x 9.8mm (black)

Work

Warning: There is no anti-trap feature fitted to the linkage flaps, front header panel, tension bow or
tonneau cover. Ensure all persons are clear of the mechanism, and there are no obstructions in the
vicinity during the operation of the roof.

Caution: To avoid a clash of panels it is important that the luggage compartment and tonneau cover
assembly are not opened at the same time. One of these must be fully closed at all times

Note: To carry out the following procedures, the power operated roof assembly will have to be
positioned partially open in a transient state. With the ignition on any transient roof position will only
be maintained for 10 minutes after which a warning will sound prior to the roof assembly gradually
folding down as the hydraulic pressure decays. Therefore to enable the following operations to be
carried out the roof has to be secured using 2 ratchet straps linked together (part number T10038)
(see inset Figure 3)

Caution: Whenever air tools are employed or compressed air is used to remove debris it is imperative
that the air is clean and dry and does not contain any lubricants. The exhaust from an air tool supplied
with lubricated air is likely to stain the hood

Note: Only check and if necessary repair the rivet on the left hand twin bow as shown in figure 3.
There are no known issues with the similar rivet on the right hand twin bow

E773/7

Campaign number E773

1. With the ignition on, use the power operated roof open and close buttons to position the roof
partially open. It is recommended that the roof position is maintained primarily with the ignition still
on, and secured using a pair of tensioning straps (T10038) linked together.
2. Note: The vehicle must be adequately protected from the swarf that will be produced during the
following operation. When removing rivets a 6mm drill is best suited to remove the rivet head
before extracting the centre of the rivet with a 3mm parallel drift. Eye protection must be worn

Figure 4
3. Referencing figure 3, identify the lower rivet on the left hand twin bow. With the roof positioned as
shown in figure 3. Drill out the rivet (see Figure 4), ensure no trim or cords are in contact with the

rotating surfaces of the drill.

Rectification measure

Figure 7
1. A hole 5.5mm in diameter and 6mm in depth has to be drilled from the rear face of the bow to
produce fig ure 2B. Using a method of ensuring a depth of 6mm is not exceeded , measured from
the drill tip, produce the 5.5mm counter bore from the rear of the bow (see Figure 7)
2. Apply a coat of black paint to the hole, both for cosmetic and oxidation suppression purposes

3. Re attach the strap with a new oversize rivet (part 'B' figure 1) (see Figure 8)

Identification

Figure 9
On completion apply a campaign completion mark to the rear of the bow adjacent to the replaced
rivet. If the part used is the standard rivet (A) then apply a green completion mark.
If the rectification measure had to be performed and therefore the larger rivet (B) was used then apply
a white completion mark (see Figure 9)
