This document is a Test Procedure for the operational testing of #1 and #2 Collection, Holding, and Transfer (CHT) Pump Units for the USS Nueces (APL-40) at the Ship Repair Facility - Japan Regional Maintenance Center, Det Sasebo. The test procedure covers the replacement of two sewage transfer pumps, each with specific specifications: a centrifugal pump with 100 GPM capacity and 70 ft total head, powered by a 7.5 HP motor operating at 1800 RPM with 440V input.

The comprehensive test procedure includes detailed requirements for equipment preparation, calibration, safety precautions, and operational testing. Key testing steps involve conducting insulation resistance tests, motor rotation checks, heat run tests, and vibration analysis. The procedure specifies acceptance criteria for various parameters including input voltage (396-484 Volts AC), motor current (10.7 Amps max), motor speed (1,745-1,800 RPM), and temperature limits for motor frame and bearings. The document is designed to certify the satisfactory operation of the CHT pumps after motor and pump overhaul, with rigorous guidelines for equipment inspection, testing, and documentation.
