Northstar Trailers SPORTSTAR III - Manual (Page 11)

a. Remove the plastic caps from the rear corners of the trailer frame.
b. Attach the rear corner brackets (12) to the frame using 1” bolts (L), small
flat- washers (K) and small locknuts (V); install this bolt horizontally. Also
use two 3 ¾” bolts (W), flat-washers (K) and a small locknut (V) to fasten the
bracket to the frame; install this bolt vertically.
c. Replace the plastic caps. Note: RTV sealant or silicon may be applied to the
circumference of the plastic caps to prevent rust, and to ensure that the cap will
not fall off while in tow.
d. Slide the side-rail (3) opening over the knob on the back of the bracket. Lay
the side-rails alongside the trailer so the bolt-tab on the side-rail lays snug
with the outside of the bolt-tab on top of the fender. Fasten the side-rails to
the fenders using 1” bolts (L), flat-washers (K) and lock-washers (J). Do not
fully tighten yet.
e. Ensure that side-rail pin-slots are positioned in-between the pin-slots on the
trailer frame, and then insert the side-rail pins (F). Secure the pins with a
cotter-pin (M), and secure cotter-pins by bending at least one leg to 90
degrees.
ASSEMBLE FRONT CORNER BRACKETS (with ramp mounts)
a. Thread a large nut (H) onto the ramp pin-bolt (G). Tighten the nut to the end
of the thread where it borders the smooth surface of the pin-bolt.
b. Slide a lock-washer (I) over the pin-bolt threads and position it flush against
the nut.
c. Twist the ramp pin-bolt into the front corner bracket (4) until the lock-
washer is flush with the bracket; the ramp pin-bolt will extend
approximately 1/8” through the nut welded onto the backside of bracket. You
will need to use a wrench to fasten the ramp pin-bolt to the bracket.
INSTALL FRONT CORNER BRACKETS (with ramp mounts)
a. Install the retaining cables (S) by looping them over the round knob on the
back of the bracket.
b. Insert the knob on the bracket into the hole of the side-rail.
c. Attach the bracket to the trailer frame using 3” bolts (X), flat-washers (K) and
small locknuts (V).
TIGHTEN AND SECURE ALL BOLTS! After all side-rails and brackets are in their
proper positions, make sure to securely tighten all bolts, and make sure that all
