will be available only as part of a sub-assembly. The
detail parts

the assembly; but certain parts,
due to manufacturing procedures or installation proce-
dures, are recommended and furnished as part of a sub-
assembly. The renewal parts data indicates which parts
are available as individual items
or
in a sub-assembly.
When inquiring about

ordering parts, refer to the fig-
ures

this book and the renewal parts data for identifica-
tion of the part

IDENTIFYING PARTS FOR DS-4165 AND
DS-2065
13.1.1 DS-4165 Parts
The parts of a DS-4168 are almost identical to those of a
DS-420. The parts shown in a proper DS-420 figure (or
drawing) are used for the same purpose
in
Type
DS-4168. Description
of
these parts are the same too,
but they are identified as parts for DS-4168 (or shop
order number).
13.1.2 DS-2065 Parts
The parts of Type DS-2068 are very similar to those of
DS-206. By reference to the proper DS-206 figure (or
drawing) identification
of
their common parts can be
made. When they are ordered for the DS-2068, it is so
specified. The major differences are:
1.
DS-2068 uses the three piece base of the DS-416,
instead of the one piece molded base of the DS-206.
2. DS-2068 uses the DS-416 arc chute.
3.
DS-2068 main disconnects have 50% more fingers
than the DS-206.
4.
DS-2068 has twice as many contacts and arms as
the DS-206.
5. The pole unit hinge of DS-2068 is a forked construc-
tion
or
a miniature version of the DS-416 hinge.
