American Governor Company (AGC) is to help rehabilitate the US Army Corps of Engineer’s McNary Dam, after being awarded a major subcontract by Olsson Industrial Electric.

The contract is part of a sweeping station service rehabilitation that includes the overhaul and modification of 35 Governor Oil Pumps. The primary thrust of the work involves rewinding the motors to match the new station service voltage (480VAC). AGC’s Training and Repair Facility in Amherst, Wisconsin will also overhaul the 27 Woodward XX Herringbone Gear Pumps and add Solenoid-Operated Unloader Kits to improve the operation of these pumps.

As part of the work, each Woodward XX Herringbone Gear Pump will be disassembled, cleaned, and inspected. Pump and motor bearings will be replaced and new gaskets, seals, and O-rings will be installed, all from AGC’s in-house Woodward spare parts stock.

Each pump’s gears will be inspected and dressed as needed, and the 4160VAC motors will be completely disassembled, tested, modified and rewound for 480VAC operation. Then, each governor oil pump assembly will be reassembled and tested on the company’s new Full-Flow Pump Test Stand.

In a statement, AGC said it "will work diligently and coordinate closely with Olsson Industrial Electric, the project’s prime contractor, to ensure that the Governor Oil Pumps are removed, repaired/rewound, and returned on a timely basis so as not to delay the progress of this massive Station Service Rehab project".
