Refitting The Rear Cap Assembly And Fitting The Sunshield
1. Refitting the Rear Cap Assembly.
Note: Before refitting the Rear Cap
Assembly, test the Camera functions
and check that the lens dust cover is
removed!
a) Take care that the ‘O’ ring seal is
free from grit and dirt. Lightly
grease the ‘O’ ring and the flame
path zone (shoulder/neck) of the
Rear Cap Assembly with clean
general purpose grease.
b) Lightly grease the ‘O’ ring and the
locating spigot at the front of the
Monorail with clean general
purpose grease.
c) Present the Rear Cap Assembly to
the housing Body, taking care to
maintain the correct rotational
alignment.
d)
If the optional Wiper Unit
Kit (FH07W) is fitted:
i) Ensure that the wiper arm is
resting in the PARK position.
ii) Confirm that the rear wiper shaft
coupling is correctly aligned with
the wiper drive unit mating-half
coupling.
e)
Locate the Monorail locating
spigot into the circular groove in
the bottom of the Body.
f) Slide the Monorail into the Body.
Fit the 2 off Cap Fitting Guide
Screw into a diagonal pair of fixing
holes (say 3 and 4) to ensure that
all the fixing holes line up. (See
Figure 13.) Partially insert the
Rear Cap Assembly into the Body
until the 6 off M6 x 25 screws can
engage. Remove the 2 off Cap
Fitting Guide Screws and retain for
future use. Note: Care should be
taken to avoid damage to the
flame path zone. (See Figure 2.)
g) Refit the 6 off star washers and
the 6 off M6 x 25 Cap Head A4-80
stainless steel screws. Tighten
the screws evenly to a Torque
rating of 4.5Nm, in the order as
shown in Figure 14. It is essential
that only A4-80 screws be used.
