practice

to

place
parts
in
a

part

so
that

they
can
be
reassembled
in

Added
care

should
also
be
exercised

to

prevent

springs
and
other
small

parts
from

being
sca

and
lost

Before

dip
all

parts
in

clean
automatic
transmission

fluid
and

check
to
be
certain

that

they
are
free

of

lint
and
other
minute

particles
If

is
burnt
or
if

the
