(7) Run a qua rt of fluid throu gh the system then
st op t he en gine and install the ret urn line/lin es.
(8) Fill th e system with flu id and perform Steerin g
Pump Init ial Operation, (Refer to 19 - STEERING/
PUMP - STANDARD P ROCEDURE).
(9) St art th e engine a nd run it for fift een min utes
then stop the engine.
(10) Remove the retur n line/lin es from the pu mp
and plu g th e pump port/por ts.
