All daily, weekly, and monthly maintenance items were completed.
Continued testing irrigation pump kilowatt-hour meters, which were due

Unit 2 governor was repaired during the month. The governor acted
erratically and hunted whenever we attempted to synchronize to the
line. The dashpot was disassembled and examined. Several new parts had
to be manufactured, including the main dashpot piston. After repair,
the governor is operating normally.

Unit 7 was returned to service after sandblasting and painting of the
scroll case, draft tube, and runner. Corrective maintenance was
performed on runner and discharge cone with molecular metal. All
electrical and mechanical maintenance items were performed, and the
unit was cleaned. The unit was ramp tested. Governor pump-up time was
dramatically improved by rebuilding the check valve on the pressurized
governor oil pipeline.
