Nev-R-Lube Drums/Bearings

All Trade Wind models are equipped with Nev-R-
Lube bearings. Dexter's Nev-R-Lube bearings are
comprised of opposed tapered roller bearing cones
sealed inside of a precision ground, one-piece double
cup arrangement. These bearings are designed with
a small amount of axial end-play. The end-play is
essential to the longevity of the bearings service life.

Nev-R-Lube Bearing Inspection

1� Jack trailer at marked JACK location pad behind
axle on main frame.
2� Check for excessive wheel end-clearance by
pulling the tire assembly toward you and by
pushing the assembly away from you. Slight end-
play is acceptable (0.001 to 0.010 in.).
3� Rotate tire slowly forward and backward. The
wheel assembly should turn freely and smoothly.
4� Excessive wheel end-play, restriction to rotation,
noise, or bumpy rotation should be remedied by
replacing the bearing unit.
5� Bearing units should be inspected every year or
12,000 mi., whichever comes first.
A slight amount of grease-weeping from the seal area
is normal. Excessive leakage may indicate abnormal
bearing operation. Bearing end-play inspection,
drum removal/installation, and bearing replacement
procedures are described in the Dexter Operation
Maintenance Manual enclosed in your owner's packet.
Airstream recommends that these procedures are
performed by a qualified Dexter service technician, due
the need of specialized tools and training.

Brakes

Due to normal brake lining wear, the brakes and the
controller setting should be checked and readjusted
every six months or 10,000 miles, whichever comes
first.

Power Jack

The power jack manufacturer's owner's
instructions and parts list can be found by
scanning this QR code and navigating to the
instructions on Barker's website at
barkermfg.com/. The following are basic maintenance
requirements. Please refer to Barker's instructions for
jack and bubble level adjustments, installation, and
additional maintenance.

Power Jack Maintenance

• Once a year, the powerhead should be removed,
and a liberal amount of grease (preferably grease
with a high melting point) applied directly to the
coupling on which the drive pin rests. Do not pour
oil into the top of the jack post.
• Once a year, the housing cover should be removed
and the gears inspected for proper lubrication.
Remove all four screws and tap around the edge of
the housing to free the cover. Do not use or insert
a screwdriver blade to remove the cover, as it may
damage mating surfaces. If lubrication is needed,
use Mobilith SHC
TM
mating surfaces before replacing the cover.
WARNING
Avoid the risk of injury to yourself and others.
Keep hands and feet from under the foot plate
when using the jack. Do not use or install dolly
wheels on the power jack. Do not operate the
toggle switch with the manual crank handle in
place. Failure to comply could result in serious
NOTE
When operating the power jack, pause briefly
between switching up and down. Rapidly
switching from up or down may cause the
breaker to trip, momentarily interrupting power to
the jack.
