IMAGES OF PARTS AND HARDWARE [
INVERTED ASSEMBLY This trailer requires inverted assembly. (Assembled upside-down). Start by turning the trailer frame upside-down so the trailer deck is facing the ground. Use a table robust enough to support the weight of the trailer frame and high enough to elevate the frame to waist-height, or place the corners of the frame on buckets, or use sawhorses to elevate each end. CAUTION: This trailer is heavy. More than one person is required to flip the trailer frame and assembly this trailer.
STEP 1: LEAF SPRING & AXLE ASSEMBLY a. Flip the trailer frame (1) upside-down, and place the frame on a waist-high table or other elevated supports in order to facilitate assembly. b. Position the leaf-spring (8) on the frame’s spring casing (welded to the frame) so the eye in the leaf-spring is positioned toward the front of the trailer and aligns with the bolt eyehole in the spring casing. c.
STEP 2: WIRE ASSEMBLY Note: when standing at the back of the trailer looking toward the front, with the trailer still inverted, the wiring harness bundle with the YELLOW wire will be threaded along the DRIVER’S side (right side when looking at the trailer upside-down) to the brake/signal light, and the bundle with the GREEN wire will be threaded along the PASSENGER’S side (left side) to the brake/signal light. RUN WIRE a. Locate the first rib back from the front of the trailer.

STEP 3: ATTACH WHEELS TO AXLE Note: the hub assembly comes attached to the wheels with pre-lubricated bearings and washers. Upon removing the dust-caps take special care to not drop the bearings or get them dirty. a. Carefully remove dust-cap from the wheel (7) by gently prying around the edges of the cap with a small, flathead screwdriver, or by using a long bolt to gently drive through the backside of the hub and into the cap. b.
STEP 4: ATTACH TONGUE TO FRAME Remember: the trailer is still upside-down, so all components must be installed upside-down. a. *Make sure that the tongue’s wiring harness extends through both the backside and the front of the tongue. b. Align the tongue’s (2) eyeholes with the eyeholes on the frame. c. Use the 3 5/8” threaded pin-bolts (E) and large nuts (H) to fasten the tongue to the frame. Note: do not fully tighten the bolts or install the cotter-pins until the side-braces are installed.
STEP 6: ASSEMBLE AND INSTALL LIGHTS INSTALL TAIL/BRAKE LIGHTS a. Fasten the taillight/brake light L-brackets (Q) to the frame using two, 1” bolts (L), and one small lock washer (J) for each bolt. b. Remove the nuts from the back of the taillight (O). c. Determine the length of the wires needed to connect the wiring harness with the light, then twist the wires together to shorten the wire slack. d. Place the loop from the harness’s white ground wire over the closest stud on the back of the light. e.
INSTALL RUNNING LIGHTS a. The white wire from the harness is not needed for ground on this light and can be capped off (with wiring connector (U)) or tied to other wires in the harness with a small zip-tie. b. Connect the brown wire from the running light (P) with the brown wire from the wiring harness by pushing the wires together. c. Position the brown wire under the silver tab, between the tab and the lens.
STEP 8: INSTALL PANELS Note: fasten bolts to finger-tightness until all the panels are in place—this will allow you to make alignment adjustments if needed. Once all parts are aligned and secured, tighten all bolts. a. Attach the front panel (3) to the front section of the trailer frame using the dowels (AA), flat washers (K) and small locknuts (I). b. Position the side panels so the front corners vertically fit on the outside (on top of) the length of each side of the front panel. c.
