This section provides listings of all field-replaceable parts
and an illustrated parts breakdown for the disc drive, as
well as replaceable part ordering information.
Replaceable parts for the disc drive are listed in dis-
assembly order in tables 6-1 through 6-12 and illustrated
in figures 6-1 through 6-12. In each listing, attaching
parts are listed immediately after the item they attach.
Items in the DESCRIPTION column are indented to indi-
cate relationship to the next higher assembly. In addi-
tion, the symbol "- - -
x - - - "
follows the last at-
taching part for that item. Indentation is as follows:
d. MFR CODE. The five-digit code that denotes a typ-
ical manufacturer of a part. Refer to table 6-14 for a
listing of manufacturers that correspond to the codes.
e. MFR PART NO. The manufacturer's part number
of each replaceable part.
f. UNITS PER ASSEMBLY. The total quantity of each
part used in the major assembly.
The MFR CODE and MFR PART NO. for common hard-
