Wheel Lugs
When the wheels are newly installed on your recreational vehicle, the lug
nuts MUST be tightened numerous times because the powder coat paint
on the wheel
is thick. You MUST re-torque lugs at 50
and 200 miles. A
decal on wheel may require re-torqueing sooner.
After your first trip, check the wheel lugs periodically for safety. The lug
nuts should be tested for looseness in spring before first trip out, or after
extensive braking. Size of lug nut is 13/16.
Over torque, exceeding 150
foot pounds, will damage components. Normally the nut fails first
however the embossing on the wheel can also be damaged and fail
to keep wheel tight.
Wheel Bearings
All wheel bearings are pre-lubricated during assembly of axles and
brakes. Your coach (since 2014) may have “ultra-lube” method, which
has a grease fitting in the end of axle beam on both sides. To lubricate
bearings, remove rubber cap, and use standard grease gun to insert
grease, 8 to 10 pumps into the bearings, if the bearings were not
repacked before leaving on a trip. Don’t forget to repack bearings as per
maintenance manual when you return home, using correct wheel bearing
grease.
Brakes - Electrical
Electric brakes on your recreational vehicle are designed to work in
conjunction with brakes on your tow vehicle. This means to have the best
brake performance on both systems, the trailer and tow vehicle MUST
perform together. Any attempt to use either alone, will cause accelerated
wear, damage, and possible accidents.
A brake control must be installed in your tow vehicle, normally below your
dash board to activate brakes, using 12-Volt DC power. Electronic type is
the most widely used and recommended. Each brand has their own
operating instructions.
Power from the battery is sent to the con
troller, the “switch” to provide the
correct amount of current to brake assemblies on the coach. As you press
harder on the pedal, the more current will flow, applying more brakes,
increasing braking capability. Keep the battery in tow vehicle and its
charging system in good working order to ensure available energy when
required.
Wiring to operate your brakes must be sized in both vehicles, suggesting
12 or 14 gauge minimum for your tow vehicle. Your coach has 14 gauge
from front end to brakes. Brake assemblies are wired in parallel, never in
series. Being parallel, there will be equal voltage and amperage at each
brake assembly.
Use the foot pedal control for general operation on combined use of both
brake systems. Manual control is to be used only in special situations,
