Bird

E.

The

Carrier

Mechanism

(See

Drawings

Pages

3-086

and

3-087)

used

by

Looney

Bird,

the

Moon

and

Sun

are

basically

the

same.

1.

The

only

difference

between

the

two,

is

that

the

carrier

for

the

Bird

has

5/8"

Pillow

Blocks

for

the

Head

Turn

mechanism,

and

is

larger.

2.

One

problem

with

the

carrier

is

that

the

1/2"

Super

8

Pillow

Blocks

wear

out,

and

looses

ball

bearings.

To

replace

a

1/2"

Pillow

Block:

a.

Loosen

the

1/2"

Pillow

block

in

question

from

the

carrier.

Remove

the

screws

and

place

them

to

the

side

for

reassembly.

b.

Remove

the

shaft

cap

(A),

and

place

it

to

the

side.

c.

Get

the

replacement

pillow

block.

d.

Loosen

the

1/2"

jam

nut

(B)

on

the

shaft,

and

unscrew

the

shaft

from

the

block

(C)

•

e.

Lift

the

shaft,

and

remove

and

replace

the

1/2"

Pillow

block

in

one

step.

f.

Re-attach

the

pillow

block

to

the

carrier,

actuate

the

movement

and

check

for

a

smooth

movement

on

the

shaft.

3.

If

the

set

screws

in

the

neck

mount

blocks

(D)

will

not

hold

up

the

head,

you

can

place

a

5/8"

Shaft

Collar

on

top

of

the

upper

block

(D)

for

added

support.

If

the

set

screw

holes

are

oversized,

drill

and

re-tap

them

to

the

next

larger

size

tap.

If

re-taping

the

holes

is

impossible,

replace

the

carrier

frame.

4.

If

the

welded

carrier

to

cylinder

mount

(E)

breaks,

replace

it.

To

replace

the

Bird's

carrier

to

cylinder

mount,

you

will

first

have

to

remove

the

head

and

neck

shaft.

5.

For

any

problems

in

the

Tol-0-Matic

cylinder,

refer

Pages

3-009

and
