5.4.3.2 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.
