12� Install new grease seal in hub or rotor using
wooden or rawhide mallet�
13� Install hub and drum on spindle�
14� Install outer bearing�
15� Install washer and spindle nut�
16� While rotating the wheel, tighten the spindle nut
with a 12" wrench until there is a slight tension�
Then back off one notch and install cotter pin.
There should now be from .001" to .010" end play
in hub. If not, back off one notch.
17� Check the lug nuts at 10, 25 miles and recheck at
50 miles of travel. See Specification Section in this
manual for wheel torque ratings.
When packing bearings by hand, place a glob of
grease in the palm of one hand and push the large end
of the bearing down into the grease. Keep turning the
bearing around and forcing it down through the grease
until the grease is extruded up through the opposite
end� Wipe the extra grease in your hand around the
outside of the bearing. It is not necessary to fill the hub
and dust cap with grease�

Brakes

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

Breakaway Switch

1� Pin
2� Breakaway Switch
To prevent corrosion within the breakaway switch, pull
the pin out and spray the inside of the switch through
the hole with an electric contact cleaner (such as Spra-
Kleen). Applying a drop of light household oil on the pin
and the groove near the base of the pin will allow the
pin to operate freely. Immediately reinsert pin. Perform
this procedure every 90 days�
CAUTION
Allow no more than 20 to 30 seconds pin
separation as damage to brake magnets may
occur.

Battery (Lead Acid)

Your Airstream trailer is factory equipped with an
Interstate battery (SRM-24)� When solar panel
equipped an AGM GPL-24 battery will be installed�

Battery Amp Draw and Testing

All batteries will have an Amp Hour (AH) rating� The
AH rating on a battery is its C/20 rate or 20 hour
discharge rate� As long as a battery is discharged over
a 20 hour, or longer period, it will deliver 100% of its
rated capacity. If it is discharged in less time at higher
currents it will deliver less capacity�
For example, a battery with a 100 amp-hour capacity
can deliver 1 amp for 100 hours or it can deliver 100
amps for one hour. Batteries are able to deliver current
longer if they are discharged at a lower rate and deliver
less current at a higher discharge rate�
For proper load testing the battery needs to be fully
charge and the voltage should be greater than 12�8
volts� A typical load test should be 3 times the amp
hour for 15 seconds. At the end of 15 seconds the
voltage of the battery should stay above 9.6 volts. If the
battery cannot reach a fully charged voltage of 12.8 or
greater the batteries will need to be equalized�
NOTE
When checking the state of charge the battery
needs to have been disconnected from a charging
source and any loads for a minimum of four hours.
Before removing the batteries verify that shoreline
power is not connected. Risk of electrical shock
may be present.
The following chart shows the approximate % of
charge SOC (State of charge) vs. OCV (Open circuit
voltage) and specific gravity for Interstate batteries.
