refrigerating capacity of the sys-
tem. The compressor oil cannot
be checked while the compressor
is installed on the car.
The oil level in the compressor
should not be checked as a matter
of course such as is done in the
car engine crankcase. The com-
pressor oil level should be ques-
tipned only in cases where there
is evidence of a major loss of
system oil such as:
1. Broken hose or severe
fitting leak.
hose
2. Oil sprayed in large amounts
under the hood due to a very
badly leaking compressor seal.
3. Collision damages to system
components.
To check the oil and to determine
amount to install in compressor,
the compressor must be removed
and drained. This same procedure
is used to determine amount to
install in a replacement com-
pressor, or in a compressor that
has been disassembled for repair.
To drain compressor, remove
drain plug and place compressor
in a horizontal position with drain
plug opening downward. Allow all
oil to drain into a container,
measure total amount, then dis-
card oil. To determine the amount
of oil that should be installed in
the compressor if there has been
a major loss of oil, when replac-
ing a compressor with a service
compressor; or when compressor
has been disassembled and re-
built, use the following chart.
IMPORTANT: If oil drained from
compressor contains any foreign
materials such as chips, or there
is evidence of moisture in the
system, it will be necessary to
replace receiver-dehydrator and
flush the other component parts
with Refrigerant-12 (subpar. 1).
The full charge of 10-1/2 oz. of
oil should then be added to
compressor.
NOTE: The service compressor
will also contain 10-1/2 oz. of
525 oil. In most cases, it will be
necessary to drain all of the oil
from the service compressor,
then install oil so that it will be
the required amount determined
by the chart.
During normal service operations
where a condenser, receiver or
evaporator is replaced with a new
unit and where no major loss of
