Nev-R-Lube Drums/Bearings

Wide-body trailers, 25 foot and larger, 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.

Replacing Power Head

It is essential that the following procedure be used
before the power head is replaced on the post:
1 With 12-volts connected, ground the power
head to trailer A-frame. Operate main switch in
post-retracting direction until the motor stops
automatically.
2 Using emergency handle, crank post clockwise by
hand until fully retracted, then turn crank one turn
counterclockwise.
3 Replace head on post and make sure drive pin
is engaged with post coupler. Tighten Allen set-
screws.
CAUTION
Be sure to follow manufacturer instructions.

Power Head Maintenance

1 Every two years, remove screws and cover and
check grease condition. Use HMP grease, similar
to lubricant 630AA, and spread on gear teeth.
Grease is not required on the nylon timing gears.
No internal lubrication of the post is required, but
an occasional external application of a silicone or
WD-40 spray lubricant on the inner tube of the post
when extended is permissible.
2 Before replacing the cover, ensure the plate and
limit switch unit are located correctly.
3 Apply a little sealing compound around the mating
surface of the gear cover and replace screws,
tightening them diagonally. Check synchronization
if head has been removed from the post.
4 Apply a little penetrating oil on the Allen setscrews
occasionally to help prevent corrosion and difficult
removal.
NOTE
Leave tow vehicle transmission in NEUTRAL when
lifting both units. Do not use dolly wheels. Always
retract stabilizing jacks before using your Jack
under load.
