ning and ch ecking of bearings, replaceme nt/rectification of defective items, greasing of bearing, if required, making minor modifications in its mounting arrangement, wherever required, assembling and its mou nting on the motor base plate or on mechanical equipment, as the case may be, incl uding levelling and alignment, checking insulation resistance and improving the sam , if necessary, checking of internal connections etc. All work associated with revisioning of motor shall also be inc luded such as uncoupling and removing of motor from mechanical equipment, disassembling, cleaning, checking of insulation resistance and improving the same, if necessary, regreasing and replacing defective items/bearings on foundation, wherever required, reas sembling, placing, levelling, aligning and fixing of coupling of the revisioned mo tor with mechanical equipment. or at site in correct sequence wherever the motors are delivered in dismantled stat .. base frame, bearing pedestals, armature, field frame etc. in separate packages. Erection, alignment and securing shall be done under expert tec hnical supervision. Optical equipment/instruments shall be used for alignment. The height of the shaft of the motors shall correspond to the achine to be driven, if discrepancies are encountered these shall be compensated by inserting machined metal simplates under the upports of the motor. The motors mounted on the movable base frames/base plates shall be connected via intermediate terminal boxe with flexible cables. After the complete installation of the motors, all bolts and bo lted joints of the mechanical and electrical equipment shall be checked to ensure that they re done up tightly by torque wrench. further check shall be made to ensure that th armature can be easily rotated. The insulation resistances of the coils and connecting leads wi thin the machine shall be check
