COMPONENT
PARTS

The

transmission
consists
of

many

small

parts
that
are

quite
alike
in

construction

yet
machined
to

very

close
tolerances
When

disassembling

parts
be
sure
to

place
them
in

order
in

a

part
rack
so

they
can
be
restored
in

the
unit
in
their

proper
positions
It
is

also

very
important
to

perform

tional
