replacement procedures for
fi
ttings and hoses.
1. Lower the snowplow completely.
2. Carefully note hose routing for proper reassembly.
3. Loosen hoses or
fi

Procedure for Installing Hydraulic Fittings
and Hoses
NOTE: Overtightening JIC hose
fi
tting ends will
result in a fractured
fi
tting.
DO NOT
use any type of sealant or tape on the
fi
ttings or hoses. This could damage product. Always
use two wrenches to ensure proper tightening of
fi
ttings and hoses.
WARNING
Lower the blade when the vehicle is parked.
Keep 8 feet clear of the blade when it is being
raised, lowered, or angled. Temperature
changes could change hydraulic pressure,
causing the blade to drop unexpectedly or
damaging hydraulic components. Failure to
do this could result in serious personal injury.
MAINTENANCE
Use the following procedure to install SAE O-ring
fi
ttings in valve block and rams:
1. Turn jam nut on
fi
tting as far back as possible.
2. Lubricate O-ring with clean hydraulic
fl
uid.
3. Screw
fi
tting into port by hand until the washer
contacts the port face and shoulder of the jam nut
threads.
4. Unscrew
fi
tting to proper position, no more than
one full turn.
5. Using two wrenches, hold
fi
tting body in position
and tighten jam nut until the washer again
contacts port face, then tighten an additional
1/8 to 1/4 turn to lock
fi
tting in place. Final torque
on the jam nut should be approximately 20 ft-lb.
Use the following procedure to install hydraulic
hoses:
1. Screw
fl
are nut onto
fi
tting
fl
are and hand tighten.
2. Align hose so there are no twists or sharp bends
and so that it will not be pinched or pulled by
moving parts.
3. Using two wrenches, hold the hose in position
and tighten
fl
are nut 1/8 to 1/4 turn beyond hand
tight. Final torque on the
fl
are nut should be
approximately 20 ft-lb.
Once all parts are installed, top o
ff
the hydraulic
