Maintenance [ID 585] 6.3.6 Assembling the bearings General Fitting the bearings Note Take great care and pay attention to cleanliness when fitting and assembling the bearings. Pay attention to the correct assignment of the bearings. To fit bearings, heat the ball bearings and inner rings of the cylindrical roller bearings to about 100°C in oil or air and then press them onto the shaft at the bearing inner ring as far as the shaft shoulder. Fill the bearings with the specified grease so that they are flush (cf. section on "Grease types"). Notice Avoid any heavy blows that might damage the bearings. Check that the existing sealing rings are in the proper condition. Renew them if they no longer provide a proper seal. In addition, please observe the following installation conditions: •= Thoroughly saturate new felt rings in high-viscosity oil (lubricating oil to DIN 51517-C100) heated to about 100 °C before fitting in the bearing covers. The design of the rings should be such that the shaft slides easily in them but is still well enclosed by them. •= When installing outboard V-rings, note that the V-ring is in the correct axial position when the end face of the bearing cover is flush with the outer edge of the V-ring. The use of a suitable auxiliary disc for assembly purposes is recommended. •= To protect the V-ring against mechanical effects in special cases there may be an additional sheet-metal protecting ring fitted in the outer bearing cap (or in the bearing end shield). The protecting ring should be inserted in such a way that the ring is still sufficiently preloaded and that one of its two slots coincides with the water drain slot provided at the low point of its seat in the bearing cap (or bearing shield assembly). •= If rotary shaft seals are fitted without spiral springs, the replacement part must also be fitted without springs. •= In the case of a tacho-generator with an inboard V-ring at the outer bearing cover, the V-ring must sit against the collar of the journal.
