quick-disconnect fitting, be sure to use a relief coupler or
low-seep coupler. If the fan return line is completely sealed by
a poppet or check valve fitting, fan seals could be damaged.
Normal temperature changes can cause damaging oil pressure
changes in a completely sealed fan hydraulic system.
183. Remove any protective plug from the QD fitting ,
and from the MORB end of the hose .Attach the
QD coupler fitting to the MORB end of the
hose . This hose is the return hose .
