The weight of the trailer can more than double the
load to be stopped. Always use the automatic
synchronized braking provided by the brake
controller.
Breakaway switch. The breakaway switch on your
Pacific Coachworks recreational vehicle is located
near the hitch. This switch automatically activates
the trailer brakes if the trailer becomes separated
from the tow vehicle. The steel cable lanyard from
the breakaway switch must be securely anchored to
a non-removable part of the tow vehicle. The
breakaway switch is activated when a pin connected
to the steel cable lanyard is pulled out of the switch,
thus completing a circuit from the trailer battery to
the trailer brakes.
Pacific Coachworks recommends
checking the operation of this switch before each trip.
The breakaway switch should never be used as a
parking brake.
Trailer battery. The trailer battery is the sole source
of power for the trailer brakes in case the trailer
becomes separated from the tow vehicle. There must
be a fully charged and operational battery on the
trailer side of the system. (Battery not supplied by
trailer manufacturer.)
Tires/Wheels/Hubs
Tires.
Your new Pacific Coachworks recreational
vehicle comes equipped from the factory with
major brand name tires. The tires on your trailer
were chosen specifically for that trailer and are
matched to the wheels. When replacing tires or
choosing a spare,
Pacific Coachworks
recommends using tires of the same size, rating and
construction as the originals at all trailer wheel
positions. Never mix tires of different size, rating or
construction on the same axle. And never use tires
of a lessor rating than the originals. Doing so can
be dangerous and may invalidate the trailer GAWR
and GVWR as listed on the federal certification
label located on the forward half of the left side of
your trailer. Proper inflation pressure must be
maintained. Check your tire inflation pressures
periodically when the tires are cold to see that they
conform to the cold inflation pressures
recommended by the tire manufacturer and stamped
on the tire sidewall. Remember to give your spare
tire the same consideration and care as your
mounted tires.
Wheels. The wheels (or rims) on your trailer were
chosen specifically for that trailer and are matched
to the tires.
Never use wheels of a lesser rating. Doing so can be
dangerous and may invalidate the trailer GAWR and
GVWR as listed on the federal certification label.
Pacific Coachworks recommends the following wheel
nut torque requirements:
TORQUE REQUIREMENTS
It is extremely important to apply and maintain
proper wheel mounting torque on your trailer
axle. Torque is a measure of the amount of
tightening applied to a Fastener (nut or bolt) and
is expressed as length times
force. For example, a force of 90 pounds applied
at the end of a wrench one foot long will yield 90
ft.-lbs. of torque. Torque wrenches are the best
method to assure that the proper amount of
torque is being applied to a fastener. NOTE:
Wheel nuts or bolts must be installed and
maintained at the proper torque level to prevent
loose wheels, broken studs, and possible
dangerous separation of wheels from their hubs.
When replacing wheel nuts or bolts, be sure to use
only ones matched to the cone angle of your
wheels (usually 60 or 90 degrees).
The proper procedure for attaching your wheels is as
follows:
1.
Start all nuts or bolts by hand to prevent cross
threading.
2. Tighten nuts or bolts in the sequence shown
below.
3. Tightening should be done in stages. First,
tighten all nuts or bolts to 20-25 ft.-lbs.
Then, tighten them to 50-60 ft.-lbs. Finally,
tighten them to 90-95 ft.-lbs.
4. Wheel nuts or bolts should be torqued before
first road use and after each wheel change.
Check and retorque after the first 25 miles
and again at 75 miles. Check periodically
thereafter.
Proper wheel nut torque is very important. In gener-
al, trailer wheels carry much higher loads than
passenger car or truck wheels. And, as you may
have surmised, wheels on tandem axle trailers do not
