Parts List
Many parts used in the 8600S are surface-mount devices (“SMT”) and are not in-
tended for field replacement because specialized equipment and skills are necessary
to remove and replace them. The list below includes substantially all of the parts
used in the 8600S (including surface-mount devices), and inclusion of a part in this
list does not imply that the part is field-replaceable.
See the following assembly drawings for locations of components.
Obtaining Spare Parts
Special or subtle characteristics of certain components are exploited to produce an
elegant design at a reasonable cost. It is therefore unwise to make substitutions for
listed parts. Consult the factory if the listing of a part includes the note “selected” or
“realignment required.”
Orban normally maintains an inventory of tested, exact replacement parts that can
be supplied quickly at nominal cost. Standardized spare parts kits are also available.
When ordering parts from the factory, please have available the following informa-
tion about the parts you want:
Orban part number
