Four-way wrenches, ratchets, and similar
tools can be useful for short-term emer-
gency repairs but are not appropriate tools
for accurately checking lug nut torque.
• Keep a record of the date and approxi-
mate mileage when the lug nut torque
is checked. Note any lug nut(s) that lost
torque. Investigate the reason(s) if the
lug nut torque is not maintained over
more than one re-torque application be-
cause this indicates there is something
potentially wrong with the lug nuts,
nut studs, wheels and/or hubs and that
should be corrected.
• Contact an authorized MasterCraft deal-
er immediately if any persistent lug nut
loosening (or any other lug, wheel or
axle problem) occurs.
• In the event of a wheel separating from
the trailer during use, notify an autho-
rized MasterCraft dealer. Seek prompt
professional assistance in assessing the
trailer and its gear, and retain but do not
re-use involved lug nuts, wheels and
studs. Do not repair or service the trailer
yourself. Instead, call a trained, autho-
rized MasterCraft technician.
• Use the following pattern to tighten lug
nuts. On rst torqueing pass tighten to
45 ft.-lbs. On second pass tighten to 70
ft.-lbs. On third pass tighten to 90 ft.-lbs.
On fourth pass tighten to a reading be-
tween 110 ft. lbs-120 ft.-lbs. Follow the
pattern shown in the photos at left.
Tires
The most common cause of trailer tire
trouble is under-ination. It is important,
therefore, to always maintain correct air
pressure as indicated by the tire manufac-
turer on the tire’s sidewalls. (Tire pressure
information may be listed on stickers else-
where as a convenience, but because tires
may be replaced, the air pressure should
always be veried on the tire’s sidewall. If
thereisadifferencebetweenairpressure
listings on labels, warning stickers and
tiresidewalls,alwaysdefertothetireside-
wallairpressurelisting.)
Always check the air pressure when the
tires are cold. Tires heat up and the air pres-
sure increases after traveling short distanc-
es. For safety and convenience, inate tires
to the air pressure indicated on the sidewall
of the tire, but always carry a spare wheel
and tire in case of unexpected or sudden is-
sues with a tire.
