7) Remove all crushed Cartridges from within the system.
8) Check to see that the Diaphragms are in usable condition. Diaphragms which are bowed
or have bent legs must be replaced.
9) Check the
gaps between Fender Panels
. The maximum gap allowed for these
overlapping parts (including Fender Panels overlapping Panels behind the system) is .78”
[20 mm] for
narrow systems
and 1.00” [25 mm] for
wide systems
. Be sure the Mushroom
Washer Assemblies are torqued to the end of the threads. If the gaps between the Fender
Panels are still too large, it may be necessary to replace bent parts.
Warning:

Maximum gap allowed:
Narrow Systems

10) Replace all crushed Cartridges (p. 38 & 56).
11) Remove damaged Nose Assembly. Attach the new Nose to the first Diaphragm using the
six (6) rail bolts, coupling nuts, rail nuts, cap screws, Pull-Out Brackets, and Bar Washers
that hold the Nose to the first Diaphragm. Adjust Nose to align with Fender Panels and
then tighten all six (6) nuts.
