BRAKE

MECHANISM

NOTE:

Be

sure

that

the

power

is

turned

off

prior

to

making

any

ad-

justments

to

the

brakes.

1.

Screw(A)

for

the

left

brake

(as

viewed

from

the

front)

must

be

adjusted

so

that

there

is

a

clearance

of

1

mm

between

lever(C)

and

lever(E).

Screw(A)

for

the

right

brake

must

then

be

adjusted

so

that

lever(B)

is

parallel

to

lever(C).

2.

Push

the

plunger

until

there

is

contact

at

(a);

i.e.,

until

the

clear-

ance

has

been

eliminated,

but

make

sure

that

the

plunger

is

not

pushed

so

strongly

that

the

levers

(E),

(C),

and

(B)

are

deflected

—

they

must

remain

in

a

horizontal

plane.

3.

Position

the

solenoid

housing,

while

the

plunger

is

pushed

as

des-

cribed

in

step

#2

above,

so

that

the

gap

at

(f)

(the

distance

be-

tween

the

leftmost

edge

of

the

plunger

and

the

leftmost

edge

of

the

solenoid

housing)

is

between

11

to

12

mm.

When

the

solenoid

housing

is

so

positioned,

the

plunger

should

be

able

to

be

de-

flected

between

1

to

2

mm

when

pushed

strongly.

TORQUE

NOTE:

Before

any

adjustments

or

measurements,

make

sure

the

is

off.

Mount

an

empty

7”

reel

onto

either

reel

table

and

attach

a

spring

scale

to

the

reel

with

a

string.

.

Smoothly

pull

the

scale

away

from

the

reel

under

test

and

note

the

torque

value

when

the

reading

on

the

scale

is

steady.

The

proper

torque

values

are

given

in

the

chart

below.

.

Follow

steps

1

and

2

for

each

measuring

condition;

i.e.,

(A)

through

(D)

in

Fig.

2-4.

.

If

the

forward-direction

torque

is

not

correct,

change

the

hook-

ing

position

of

the

spring

hanger

(reference

(D)

in

Fig.

2-3)

for

the

corresponding

brake

requiring

adjustment.

If,

after

the

for-

ward-direction

torque

has

been

properly

adjusted

and

the

reverse-

direction

torque

is

not

correct,

or

the

forward-direction

torque

is

still

not

correct,

check

to

see

if

the

brake

felt

pad

is

worn,

and

also

check

that

the

brake

mechanism

is

properly

aligned

as

ex-

plained

in

Section

2-3,

‘Brake

Mechanism”.

If

necessary,

replace

the

ALIGNMENT

PROCEDURE

1.

By

visual

observation,

align

the

erase,

record,

and

playback

heads

so

that

the

proper

tilt

is

obtained

for

each.

2.

Coarse-adjust

the

azimuth

of

the

erase,

record,

and

playback

heads

by

observing

each

without

a

tape

threaded.

.

Load

a

TEAC

YTT-8013

test

tape

and

play

it.

4.

The

erase

head

core

should

protrude

0.1

mm

above

the

tape

while

in

motion.

If

not,

readjust

the

azimuth

and

recheck

the

tilt

and

height.

Adjust

as

necessary.

5.

Fine-adjust

the

height

of

the

record

and

playback

heads

until

the

brass-colored

spacers

appear

above

the

moving

tape.

(The

brass-

colored

spacers

appear

about

as

thin

as

a

pencil

line.)

When

ad-

justing,

make

sure

all

the

screws

are

turned

proportionately

so

that

the

tilt

and

azimuth

previously

adjusted

is

not

altered.

6.

If

required,

make

a

coarse

adjustment

of

any

head

requiring

tangency

correction,

while

the

tape

is

running.

5.

Replace
