COMPONENT
PARTS

The

consists
of

many

all

parts
that
are

quite
alike
in

oonstruction

yet
machined
to

very

close
tolerances
When

disassembling

parts
be
sure
to

place
them
in

order
in

part

so

they
can
be

restored
in

the

in

their

proper

CONTROL

assembly

practice

to

place
parts
in
a

so
that

they
can
be
reassembled
in

proper
positions
Added
care

should
also
be
exercised

to

prevent

springs
and
other
small

parts
from

being
sca
ttered
and
lost

Before

assembly

dip
all

parts
in

clean
automatic
transmission

fluid
and

check
to
be
certain

that

they
are
free

of

lint
and
other
minute

particles
If

clutch
or
band
is
burnt
or
if

becomes
fouled
the
