Aftercooler Core - Inspect
The aftercooler is combined with the radiator, inspect
the aftercooler after the radiator and aftercooler has
been cleaned.
Inspect the aftercooler for damaged fins, corrosion,
dirt, grease, insects, leaves, oil, and other debris.
Bent fins may be opened with a “comb”. Inspect
these items for good condition: Welds, mounting
brackets, air lines, connections, clamps, and seals.
Make repairs, if necessary.

Alternator - Inspect
Perkins recommends a scheduled inspection of the
alternator. Inspect the alternator for loose
connections and correct battery charging. Check the
ammeter (if equipped) during engine operation in
order to ensure correct battery performance and/or
correct performance of the electrical system. Make
repairs, as required.
Check the alternator and the battery charger for
correct operation. If the batteries are correctly
charged, the ammeter reading should be very near
zero. All batteries should be kept charged. The
batteries should be kept warm because temperature
affects the cranking power. If the battery is too cold,
the battery will not crank the engine. When the
engine is not run for long periods of time or if the
engine is run for short periods, the batteries may not
fully charge. A battery with a low charge will freeze
more easily than a battery with a full charge.
