covers
important
overhaul
and
medium
overhaul;
it
is
also
divided
into
unit
overhaul
and
compressor
overhaul.
Medium
overhaul
refers
to
dismantling
the
compressor
to
check
and
clean
internal
surface
without
replacing
any
components.
And
important
overhaul
refers
to
replacing
the
seriously
worn
internal

If
the
parts
are
found
