Gain access to generator air cooling coils for inspection and cleaning. See RFP and manufacturer's recommendation on cleaning procedure and test. 4 . Remove end covers from generator housing. 5. Remove the top half of the two elbows on the turbine to gain access to one side of each runner. 6. Remove oil from the three bearings using a filter press and clean barrels. Leave barrels out of way, but leave in power house. (If City would like barrels removed from powerhouse then use their crane) . 7. Remove top caps from the three bearings. Protect bearings from any dust or dirt contamination. NOTE: All inspection, cleaning and testing will be done without decoupling the shaft or runners. The intention is to do as much as we can without decoupling the shaft or moving the stator. If these procedures reveal that more .'i extensive work needs to be done then that will be considered outside of the fixed price portion of this contract. 8. Begin inspection process: 1. The shaft will need to be rotated for several of the inspection and cleaning processes. To the extent practical we will try to perform as many of the steps as we can with each rotation. Be careful to properly hand oil the bearing surface each time before rotating the shaft. 1. Check generator stator wedging. 2 . Visually check the stator air cooling gap. Do not clean until bearings are properly protected from dust. 1 3 . Visually check rotor windings. 4. Check the air gap between a pole piece and the stator at eight positions (45 deg. apart) for one pole piece and one position for all pole pieces at both ends of the generator. Record the data on a generator map and determine the variation in spacing. 111 111 City of Redding Request for Proposal Major Inspection and Minor Maintenance June 8, 1989 Page Three 5. Visually inspect, feel and use a straight edge light gap to check for any rough places on the steel bearing surface of the shaft at each of the three bearings. Report and record any imperfections. 6.

Visually and with stain check for cavitation damage on the runner, exit elbow, spiral case and wicket gates (see RFP 6.a,b,c) . 8. Inspection will be carried out in part from inside the squirrel case. The City will provide the safety harnessing. 9. Use precision level to measure shaft alignment as it is rotated. 2 . Apply end pressure to the shaft and record its absolute position with respect to a fixed reference point and then its movement amount when pressure is applied in the opposite direction. With the thrust surface against the thrust shoes check spacing between each shoe and the thrust caller. Record any gaps. Attempt to check the upper shell half's thrust spacing as well. ;.i 3 . Jack the shaft as a unit enough to relieve the weight from the lower half of the bearings. 1. Roll the lower half out of the housing. 1. Inspect the babbitt on both upper and lower halves for damage or uneven wear on either the ii radial or thrust bearing surfaces. 2 . Clean out the bearing housing. 3 . Test the float switches for activation at the proper levels. Record the levels in a manner that they can be referenced latter when the bearings are filled with oil. 4 . Inspect and clean the oil coolers and flow switches. Check the flow switches for any internal build-up or fouling. 5. Measure the RTD resistance and compare it to a chart value against a known temperature. 6. Test the insulated bearing with an ohmmeter and the with megger at the manufactures recommended level. Report and repair any minor infractions. i 1 111 City of Redding Request for Proposal Major Inspection and Minor Maintenance June 9, 1989 Page Four II 2 .
