INITIAL ASSEMBLY
8.
Attach the stabilizer bars — use the ½" x 4½" bolt,
flat washers (both sides) and nut to attach the two
stabilizer bars to the pre-drilled holes in the tongue,
and the ½"-13 x 1¼" bolts and flat washers to attach
the stabilizer bars to the tabs at the front of the axle,
as shown in Figure 5.
Attach the stabilizer bars to the axle so that they
are to the outside of the tabs (inset, Figure 5), with the
flat washers to the outside.
Hand-tighten the three bolts for now — they will be
adjusted after the dolly is completely assembled.
9.
Attach the wiring harness — install a plug on the
wire harness that matches the electrical socket on the
motorhome, following the color code below.
Wiring Color Code
white .......................................................... ground
brown .................................taillights/running lights
yellow ............................................... left turn/stop
green .............................................. right turn/stop
black .......................................... power for brakes
Apply a silicone sealant (not provided) to the wires
where they attach to the plug — this will help prevent
damage from moisture and corrosion.
10.
Attach the ramps — first, slide both of the ramps
over the axle (Figure 6). Then, on the inside of each
ramp, align two of the U-brackets (Figure 6) over the
pre-drilled weldment nuts.
Attach each U-bracket to the ramps with two of
the ½"-13 x 1½" bolts, flat washers, lock washers and
nuts. Position the flat washers and lock washers to the
inside.
Torque the ½"-13 x 1½" bolts to 78 ft./lbs.
11.
Slide the ramps to the left or the right, to correspond
to the width of the towed vehicle's tires.
Align the ramps so that both tires will be centered
on the ramps, and so that the ramps will be an equal
distance from the center of the axle.

Attach the wheels — at each
wheel, finger-tighten the five lug
nuts, then use the crossing pattern
shown to the right to torque all five
lug nuts on both wheels to 90 ft./
lbs.
(If the axle has been supported,
remove it from the supports now.)
6.
Attach the tongue — position the pre-drilled hole at
the end of the tongue (Figure 4) so that it aligns to the
pre-drilled hole on the front arm of the axle. Attach the
tongue with the 5/8"-13 x 4½" bolt, cut washers (both
sides), lock washer and lock nut (Figure 4).
Hand-tighten the bolt for now — it will be adjusted
after the dolly is completely assembled.
7.
Insert the pivot pin through the pre-drilled holes in
the front arm of the axle and the tongue (inset, Figure
4) and secure it in place with the safety pin (inset,
Figure 4).

pattern to tighten
