3.2.2.i Uncoupling the Gooseneck Trailer
with Drop-Leg Jack
Follow these steps to uncouple your gooseneck
hitch trailer from the tow vehicle:
•
Block trailer tires to prevent the trailer from
rolling, before jacking the trailer up
•
Disconnect the electrical connector.
•
Disconnect the breakaway brake switch
lanyard.
•
Disconnect the safety chains from the tow
vehicle.
•
If the tow vehicle has a tailgate, lower it.
•
Move the spring-loaded gooseneck receiver
lock plate locking pin to the OPEN position
(see “Gooseneck Ball Receiver and Height
Adjustment” figure).
•
Rotate the lock plate to a position that permits
the gooseneck ball to exit the receiver.
•
Before releasing dropleg jack, make certain
ground surface below jack base will support the
trailer tongue load.
•
Rotate the drop leg plunger pin handle so that
the plunger pin is released from the drop leg
(see “Releasing Drop Leg Mechanism” figure).
•
Push down on the drop leg base with your foot
to place a drop leg to the desired lowered
position.
•
Rotate the plunger pin handle so that the
plunger pin is attempting to engage the drop leg
(see “Drop Leg Jack Mechanism” figure)
•
Slowly raise your foot, permitting the drop leg
to rise. The plunger pin will engage a hole in
the drop leg.
^ CAUTION
The drop legs are heavily spring loaded in
the lowered position. They will rapidly
return to the upper position when
released and can inflict serious bruises,
scrapes or pinching.
Keep your feet, shins and hands well
clear of the drop legs and drop leg bases
when releasing the drop legs.
•
Be sure the plunger pin is fully engaged. Push
it in by hand if necessary. The bent part of the
plunger pin handle must be touching the
plunger pin housing.
•
If your trailer has two drop leg jacks, lower
them both to the same level, following the
above instructions.
NOTICE
If the drop legs are not set at the same
level, one of the drop leg jacks can be
overloaded and can be damaged.
•
Release the handle (or crank) from its holder
and engage it with the jack shaft (see “Drop
Leg Jack Mechanism” figure 3-14).
•
Rotate the handle (or crank) from its hold and
engage it with the jack shaft.
•
Rotate the handle (or crank) clockwise to
slowly extend the jack and transfer the weight
of the trailer tongue to the jack.
•
On two speed jacks, pushing the handle shaft
toward the gearbox can perform rapid
extension. This shifts the gearbox into a high
speed mode.
•
When the drop leg base contacts the ground,
shift the gearbox into low speed mode by
pulling out on the handle shaft until it locks
into low gear.
NOTICE
Do not use high speed to lift the trailer, the
drop leg jack mechanism can be damaged.
High speed is used only to rapidly move
the drop leg base into contact with the
ground.
Continue to extend the jack(s), making sure that the
ground is providing stable and level support for the
trailer.
After the jack(s) are extended and the gooseneck
ball receiver is well clear of the gooseneck ball, to
permit driving the tow vehicle away, disengage the
handle from its shaft and return to its holder.
3.2.3 Trailer with Fifth Wheel Coupler and
Drop-Leg Jack
A fifth wheel coupler on the trailer connects to a
kingpin that is installed on the tow vehicle. A fifth
wheel coupler on the tow vehicle connects to a
kingpin that is installed on the trailer. See figures
3-17 and 3-18.
