t
' 1200 RPM generators only may be available from retired 1200 RPM 8V-71
generator sets and may not have to be purchased as part of the set.
Original 1200 RPM KATO Generators:
Wales KATO 105SU9D $.N. 67931-3 (Used for Old Harbor)
New Stuyahok KATO 105SU9D S.N. 67931-2 (Used at Wales)
New Stuyahok KATO 105SU9D S.N. 67931-1 (In Yard, Proposed for Shageluk)
Kaltag KATO 105SU9D =-S.N. 67931-4 (Still in Service)
Kaltag KATO 105SU9D S.N. 69563-1 (Retired in Village)
Shungnak KATO 105SU9D S.N. 69563-3 (Still in Service)
Scammon Bay KATO 105SU9D S.N. 67931-5 (Still in Service)
The retired unit at Kaltag should be brought back to Anchorage, tested and put
into stock as a backup unit.
Currently there is one Caterpillar 3412 1200 RPM Engine Only in stock. It
is the unit that was removed from Hooper Bay and repaired following
discovery of the block corrosion problem. If this unit is used at Chevak,
a spare unit is still needed to back up the existing 3412 at Emmonak,
Hooper Bay, Mt. Village, Noorvik, Nunapitchuk, Selawik, and Togiak.
This generator may not have to be purchased. An acceptable unit will
become available when a larger generator is installed at Koyuk.
One 268 KW 1800 RPM Generator may not be needed as it has been recommended
that the AC 685I engine at Savoonga be relocated to a village where an
existing AC 6851 is due for an overhaul. One 268 KW 1800 RPM Generator
became available following the decision to convert the Old Harbor module
unit to 1200 RPM. It is still recommended that a spare 268 KW three phase
1800 RPM generator be kept in stock as a backup unit for Ambler, Elim,
Goodnews Bay, Grayling, Holy Cross, Huslia, Kaltag, Kivalina, Koyuk,
Marshall, Mekoryuk, Minto, New Stuyahok, Noatak, Old Harbor, Pilot Station,
Quinhagak, Russian Mission, Scammon Bay, Shaktoolik, Shungnak, St. Michael,
Stebbins, Toksook Bay, and Tununak.
We currently do not have a spare KTA 1150 engine in stock to back up the
existing KTA 1150s at Alakanuk, Gambell, Nulato, Pilot Station, Quinhagak,
Savoonga, Shishmaref, and the future units at Ambler, Noatak, and Toksook
Bay.
