Inspection
a) Check the packing of the indicator cam shaft for any flaw. If the refrigerant leaks without any
flaw observed in this part, it should be due to a defect of the V-ring or installing the V-ring
without sufficient oil.
In this case, replace the V-ring.
b) Check the spiral groove of the indicator cam. If an abnormal flaw or wear is observed, replace it
with a new one.
