            bearing units using the shaft  For plum-
            mer block housings, fully tighten the
            attachment bolts for all units to the tight-
            ening torque shown in fig. 12 and accord-
            ing to table 7, page 20
              For flanged housings, securely fasten
            the second unit to the machine wall
            (fig. 13)  Align the shaft in the bearing
            arrangement axially and – if possible –
            turn it a few times  Tighten the grub
            screws in the inner rings of both units to
            the tightening torque indicated in table 7,
            page 20, fig. 14 and 15  Additionally if
            applicable, mount the end cover(s)
