3.10.4. Loose leaves of radical bearingsOn loose leaves do not make any подгоночных operations. At teases, risks or deviations replace loose leaves.
The backlash between necks of a cranked shaft and loose leaves can be defined calculation, having measured diameters of radical necks, beds under loose leaves and a thickness of loose leaves.
The nominal settlement backlash makes 0,050–0,095 mm. If it less limiting (0,15 mm) it is possible to use these loose leaves again. At a backlash большем limiting replace on these necks loose leaves new. If necks of a cranked shaft are worn out and ground till the repair size replace loose leaves repair (the increased thickness).

Sign of correctness of assemblage and interface of necks to loose leaves is free rotation of a cranked shaft.
