PIECE-PART DATA AND REPLACEMENT PROCEDURES
1. GENERAL
1.01
This section covers the information neces-
sary for ordering parts to be used in the
maintenance of the KS-13882 Ll, L2, and L3
perforators. It also covers the approved proce-
dures for replacing these parts.
1.02
This section is reissued to revise the piece-
part data, to revise the list of to.ols and
mat~rials, and to revise the replacement proce-
dures covering armature bearing pin and drum
advance checking mechanism. Detailed reasons
for reissue will be found at the end of the section.
1.03
Part 2 of this section covers the piece-part
numbers and corresponding names of the
parts which it is practicable to replace in the
field in the maintenance of the KS-13882 Ll, L2,
and L3 perforators. No attempt should be made
in the field to replace parts not designated.
Part 2 also contains explanatory figures showing
the different parts. This information is called
Piece-Part Data.
1.04
Part 3 of this section covers the approved
procedures for the replacement of piece
parts listed in Part 2. This information is called
Replacement Procedures.
1.05
After any part is replaced, it is necessary
to check the perforator on the reader and
perforator test table per SD-40040-01 or
SD-95497-01. To check the perforator, proceed7
as covered in Section 034-306-501 or 034-306-502.
In offices where this test table is not available, it.J
will be necessary to ship the perforator to a
maintenance center for check. In shipping the
perforator, use the KS-14131 carrying case as
covered in Section 034-306-701.
1.06
One dip of KS-16326 LI oil or KS-16832 L2+-
lubricant for the purpose of this section
is the amount of oil or lubricant retained on the
KS-14164 brush after being dipped into the oil
or lubricant to a depth of 3/8 inch and scraped
lightly against the side of the container as the
brush is removed.
1.07
Preparation of KS-16832 L2 Lubricant:7
This lubricant is provided in 2-ounce and
1-pint containers. A small wide-mouth container,
such as the 2-ounce jar in which the lubricant
is available, should be used as a receptacle from
which to dispense the lubricant. If allowed to
stand more than 1 day without agitation, the
lubricant ingredients tend to separate; therefore,
before each da~s use, shake' the container of
lubricant for approximately 30 seconds to in-
sure mixing of the ingredients. The proper
method of shaking the lubricant consists of re-
peated, rapid turning of the container to an
upside down position and back to the upright po-
sition. If the lubricant from a 1-pint container is
to be used, the lubricant must be mixed as just
described before it is poured into the smaller
container. Under storage conditions, the cover
should be tight on the container. .J
2. PIECE-PART DATA
2.01
The figures included in this part show the
various piece parts in their proper rela-
tion to other parts. The piece-part numbers of
the various parts are given together with the
names of the parts as listed by the Wes tern
Electric Company Merchandise Department.
When these names differ from those in general
use in the field, the latter names, in some cases,
are shown in parentheses.
2.02
When ordering piece parts for replace-
ment purposes, give both the number and
name of the piece part; for example, P-462781
Magnet Assembly. Do not refer to the BSP num-
ber or to any information shown in parentheses
following the piece-part number.
2.03
Information enclosed by parentheses is
not ordering information. This informa-
tion may be references to notes, parts referred
to in other portions of the section and not con-
sidered replaceable, or part names in general
use in the field if these names differ from those
assigned by the manufacturer.
