Visually inspect cells and windings for excessIve wean,signs of conductoroverheating or fatigue that possibly would not. be a:ppaiDnt during an 610etrical test. 2. Alf stators shall be surge- tested wl't. n electronic, surge tpsEer specifically designed 'tc apply a surge voltage stress test siCriulfiaheausly betvvec�r� tcir"ns d a coil,. bat var o' n phatsas, f"rom, vifn.ding to grsoUhd artd to doted short-clreulted turns in windinb .under test. Vesting shall Na Pea E'ASA,II Eli 622, 112 and 7.2.E ,.tandards, infrared imaging shall. be provided pre,and pest test. d. Meohanfcal fit I , Measure the b.eadhg bores, shells, housings and shaft journals LISOg a micrometer. Shaft r"its and housing fits Shall cot.oly with AR100-2015, Machine work shall be approv6d by the Engineer l�efora tieing performed or machine work may not be paid for,: Bearing journals, seal surfaces and bearing housing restoratlon shall be done by matafting and machining or baring and sleeving. Documentation of before and after measurements shall be rnade-r. 2. replace bearings per manufacturer's specifications. All grease fittings, plugs, etc, shall be replaced unless otherwise indicated by the Engineer. Bearings shall be properly lubricated and bearing oil reservoirs .aball drained for shipping an:d' installation. The Contractor shall. be responsible for filling the bearing ail reservoir upon installation. Alf equipment shall be tagged with lnformatlon as to whether or not bearing oil reservoirs were flflecl and what type of lubricant was used. e, Rotor Balancing 1, All raters of motors rated at.50 HP/3600l1300. RPM and above shall be dynarriieafly balanced,. with the rotor running at rated speed where practical, but not less than 600 RPM ir7 thebalance stand. The: balancing speedshall alab be rapid enough so the ba.lamce mane sensitivity can reliably measure the maximum allowable residua! imbalance. 2.
