This section

is

reissued

to

add

the

adjust-

ments

for

the

40P102

80-column friction

feed

printer

(noise reduced),

40P154

SO-column

tractor

feed printer, and

40P253

80-column forms

access printer.

1.03 Unless specified otherwise, adjustments

and lubrication apply

to

all printers

(80-column friction and

tractor,

132-column

tractor,

and

forms

access).

Note: When ordering replaceable

components,

prefix each

part

number

with

the

letters

"TP"

(ie,

TP123456),

unless specified otherwise.

1.04 Refer

to

Maintenance Tools, Section

570-005-S00

for

a

complete

listing

of

the

various

types

of

hand

tools

available

to

make

the

adjustments. Gauge

402617

(SO-column forms

access, SO-column friction

or

tractor),

402716

and

402717

(132-column

tractor),

and

two

40S765

gauges (132-column

and

forms access) are

required

for

certain adjustments. Also,

40286S

dynamic backup

bar

gauge

and

402878

type

carrier alignment gauge are used in adjusting

SO-

column

friction

or

tractor,

80-column forms

access,

and

132-column

tractor

printers.

1.05

To remove

the

printer

from

the

cabinet,

reverse

the

procedure

in

Section

582-210-

200

covering installation

of

the

printer.

1.06

Use

maintenance

pad

124828

to

protect

bench

top

or

floor

coverings from oil,

grease, and

dirt

while adjusting

or

lubricating

the

unit.

1.07 Some adjustments require access

to

subassemblies

that

have

to

be removed.

For

removal

of

these subassemblies, see Section

582-210-702.

1.08 The adjustments for the printer are

arranged in a sequence

that

should be

followed if a complete readjustment

of

the

printer

is

undertaken. A complete adjustment

procedure should be read before attempting

to

make

the

adjustment. After

an

adjustment has

been completed, be sure

to

tighten any

nuts

or

screws

that

may have been loosened

to

facilitate

the

adjustment, unless otherwise instructed.

1.09 The belt tensions given in this section

are indicated values and should be

checked with proper spring scales. The adjusting

illustrations, in addition

to

indicating adjustment

tolerances, show

the

angle

at

which

the

scale

should be applied when measuring belt tensions.

1.10 Some

of

the

adjustments require

the

printing

of

the

font

identification charac-

ter. This character

is

printed when

the

printer

is

running and

the

TEST switch is placed in

the

ON

position. The associated printer cover Interlock

switch must be disabled (bypassed) for printer

operation.

1.11 All tolerances in

the

adjustments in this

section unless otherwise stated, are in

inches.

1.12 When a requirement specifies a disen-

gaged clutch,

the

clutch

must

be fully

latched so

that

the

clutch shoes are completely

disengaged from

the

clutch drum.

To

become

fully latched,

the

trip lever

(or

stop

arm,

must

engage

the

clutch shoe lever, and

the

clutch disc

must rotate far enough

to

permit

the

latchlever

to

fall into

the

notch

in

the

clutch disc.

1.13 When rotating

the

clutch shaft

of

the

printer

by

hand,

the

clutch does

not

fully

disengage

upon

reaching its

stop

position.

In

order

to

relieve

the

drag

on

the

clutch

drum

and

permit

the

shaft

to

rotate

freely, apply pressure

ISS 3, SECTION 582-210-700

to

the

stop

lug

on

the

clutch disc with a screw-

driver until

the

latchlever falls

into

its

notch

on

the

clutch disc. The internal expansion clutch

is

then

fully disengaged. This procedure should be

followed before placing

the

printer in its cabinet

and switching

on

the

power.

1.14

When engaged,

the

clutch shoe lever

is

unlatched (tripped), and

the

clutch shoes

are wedged against the clutch drum.

1.15

Lubricate the printer

just

prior

to

placing

in service

or

before·

putting

it

in storage.

The printer should be relubricated

after

it

has

been in service a few weeks. Thereafter, lubricate

the mechanisms every 2,000 hours

of

running

time

or

one year, whichever occurs first.

1.16 The general lubrication requirements con-

sist

of

using KS-7470 oil

at

all locations

where

the

use

of

oil is indicated and Mobile

No.2

grease

on

all surfaces where grease

is

indicated.

Thoroughly saturate

the

felt oilers and remove all

excess oil

by

wiping lightly with a clean cloth.

The friction surfaces

of

all moving parts should

be thoroughly lubricated.

1.17 Symbols 01, 02, 03, etc, refer .to

1,

2,

3,

etc,

drops

of

oil. The following list

of

symbols applies

to

the

lubrication instructions:

o Oil KS-7470.

G Apply thin film

of

Mobile

No.2

(145867) grease.

S Saturate felt oilers, washers and wicks

with oil.

D Keep dry,

no

lubricant permitted.

1.10

Overlubrication which would allow oil

to

drip

or

grease

to

be thrown

on

other

parts

should be avoided. Capillary action and vapori-

zation

tend

to

keep a thin film

of

oil

on

the

mechanisms. This prevents

rust

and provides

sufficient lubrication

to

many points.

1.19

Closed ball bearings

do

not

require lubri-

cation. All open ball bearings should be

packed with grease (TKS-103,

195298).

16

ounces

of

tension

on

shoe release arm in a direction

to

give a maximum gap.

Rotate
