Remove the screw that secures the chassis end of the ground wire that comes
from the right-hand bowl lamp assembly.
7)
Remove two screws securing the left end of the air baffle located below the
bowl.
Caution —
In the next step, watch closely to prevent the camera from
catching on cables behind the bowl and the IR LEDs from catching on the
lower front baffles.

Flex the baffle outward. While holding out on the baffle, lift the bowl until it
clears the chassis on the left side, then move the top of the bowl outward and
lift it out of the instrument.
9)
If a new bowl is going to be installed, note how the wires are routed and
taped on the old bowl before you begin stripping it.
Replacement Notes:
P
A replacement bowl comes completely stripped. (See procedure 3.44 for
installation of the IR bowl plugs on models 720i.)
P
On a replacement bowl, secure the wires to the backside of the bowl as they
were on the original bowl.
P
Make sure the foam gaskets are properly seated between the bowl and the
fan housing of the top fan.
P
When reinstalling the bowl, carefully guide the end of the camera past the DC
power harness in the instrument chassis.
Follow-up Checks/Adjustments:
