EMI 3000 AIR CLEANER
The EMI 3000 air cleaner is a dry element air cleaner used
in late model units. Replace the EMI 3000 air cleaner ele-
ment when the air restriction indicator reads 25 in. of vac-
uum, or at 3,000 hours, or 2 years, whichever occurs first.
The EMI 3000 air cleaner element has a nameplate that
reads “EMI 3000.” It cannot be interchanged with air filters
used on previous Thermo King trailer units, however it can
be retrofit on previous units by using the EMI 3000 Air
Cleaner Assembly.

BELTS
Belts should be regularly inspected during unit pre-trip
inspections for wear, scuffing or cracking. Belt tension
should also be checked during scheduled maintenance
inspections. Belts that are too loose will whip and belts that
are too tight put too much strain on the belt fibers and bear-
ings.
Using belt tension gauge, P/N 204-427, is the best method
of checking belts for tightness. Install the belt gauge in the
center of the longest belt span. Press the plunger so the hook
will engage the belt. Make sure the hook is on the face of
the belt, not in a notch. Release the plunger with a quick
motion and without pulling on the belt. Then read the dial.
Use an average of three readings.
NOTE: Do not attempt to remove or install belts without
loosening adjustments. Belts that are installed by prying
over pulleys will fail prematurely due to internal cord
damage.
CAUTION: Do not attempt to adjust belts with the
unit running.
CAUTION: With the unit On-Off switch in the ON
position, the unit may start operation at any time
without prior warning. Switch the unit On-Off
switch to the OFF position before performing main-
tenance or repair procedures.
Alternator Belt Adjustment
The alternator belt tension should read 35 on the belt gauge.
1.
Loosen the alternator pivot bolt and the adjusting arm
bolt.
2.
Move the alternator on the adjusting arm slots to adjust
the belt to 35 on the belt tension gauge.
3.
Tighten the adjusting arm bolt and alternator pivot bolt.
