Northstar Trailers SPORTSTAR III - Manual (Page 6)

Note: the dust-cap has an exterior Zirk fitting access, and does not need to be removed
to grease the bearing. Grease the wheel bearings a minimum of 1x per year for normal
use, and up to 3x per year for frequent use in order to ensure the longevity of the
bearings. Adjust and re-grease the bearings after the first 100 miles.
STEP 3: 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 out from both the back
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 locknuts (C) 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. Be careful not to pinch or cut the tongue’s wiring harness when
inserting bolts.
d. Attach the side-braces (10) to the tongue of trailer using 3 ½” bolts (D) and
large locknuts (C).
e. Attach the side-braces to the frame using 3 ¾ ” bolts (W), small locknuts (V)
and flat washers (K). (NORTHSTAR will read upside down).
f. Once the side-braces are attached, tighten the 3 5/8” bolts from step “c” as
tight as a manual wrench will allow, then secure with cotter-pins.
g. Check and make sure that all other bolts are tight.
h. Securely tighten the bolts that connect the trailer’s coupler/hitch to the
tongue. (These bolts are loose. You must tighten them).
*Note: In rare cases the tongue’s wiring harness may fall inside the tongue after
shipping and unpacking, and you may need to fish the wires and pull them out of
tongue.
TIGHTEN AND SECURE ALL BOLTS! After the tongue and the side-braces are in
their proper positions, make sure to securely tighten all bolts, and make sure that all
