8 Install the Gooseneck with Height Adjuster
The procedure below describes how to install the gooseneck into the ground sleeve
(63-1/2”) with a height adjuster mechanism, see . Note: If you are using the standard
ground sleeve with no height adjuster, follow the instructions in Section 7. If you are
installing the gooseneck without a ground sleeve, skip ahead to section 9.
1. Set height of height adjuster mechanism (see ):
2. Measure the distance from the bottom of the ground sleeve to the ground level,
this is depth B (see )
3. Adjust the height setting on the height adjuster (dimension C in detail A of )
according to the following formula:
C = B – 61-1/8”
4. Slide the height-adjuster mechanism into the bottom of the gooseneck shaft.
Hold it in place by drilling two holes (7/32” or 15/64”) through the wall of the
gooseneck and into the guide tabs on the height-adjuster; then install two self
tapping screws in the holes.
5. Install both 5/8-11 x 8-7/8”-long threaded centering rods in the centering holes
at the bottom of the gooseneck. Install jam nuts on each end of the centering
rods. Center the rods and tighten the jam nuts against the gooseneck to hold
the centering rods in place ().
6. Thread all three 1/2”-13 jam nuts all the way onto the three 1/2”-13 x 2” long
hex bolts.
7. Install the three 1/2”-13 hex bolts into the three 1/2”-13 nuts welded into the top
of the ground sleeve.
8. Lift the gooseneck and slide it into the ground sleeve. Align the gooseneck
overhang so it is exactly perpendicular to the goal line.
9. Plumb and center the gooseneck (with respect to the ground sleeve) and
ensure that the gooseneck is properly aligned with the field of play.
10. Tighten the three hex bolts as much as possible to lock it in position.
a. Once all three bolts are pressed against the gooseneck, tighten each
bolt in sequence a quarter-turn at-a-time to ensure that the alignment is
not altered when tightening bolts.
