I. Pick up and transport to repair facility. Perform the following electrical tests, both As Received and Upon Completion: D.C. high-pot of the windings. Polarization Index. Balance check all three phases. Measure winding resistance. Record data and furnish with returned unit. Check all terminations on terminal strip and assure each wire is numbered, if not renumber all wires as necessary. Make sure that numbers are intact on existing terminal strips, repair as needed. Completely disassemble motor for inspection. Set-up and allow for a one day inspection of internals and the sampling of any contaminants by City of Columbus representatives and hired specialists. Thoroughly inspect internal parts for overall condition and any signs of contaminants, identify and provide report. Measure and record the following mechanical items: Shaft journal dimensions and fits. Bearing housing fits. Rotor total indicated run-outs. Thoroughly inspect stator for condition of ties, wedges, coils, leads, bracing system, etc. Check rotor bar continuity. Thoroughly clean, inspect, and repair all components. Including bearing housings and shaft journals, as needed. Steam clean windings and bake. Assure that each motor winding has two functional thermal overload sensors, one for Immediate use and one spare. Varnish treat windings and bake. Balance rotor before reassembling. Reassemble motor, provide and install all new bearings. Assure bearing temperature probes are functional. Check final balance after reassembly .5 mil maximum. Run motor until bearing temperatures are stable. Paint motor to match existing color. Return motor F.O.B. the Hap Cremean Water Plant, 4250 Morse Rd. Columbus, Oh.
