32. Examine a secondary shaft and its details:
– Necks under needle bearings should not have traces of fatigue failures, шлицы for installation муфт synchronizers should not have забоин and смятия;
– Persistent half rings and запорные a ring should not have wear tracks and задиров on face surfaces;
– Naves of synchronizers should not have забоин and wear tracks;
– End faces шлицев муфт and blocking rings should not have synchronizers замятия and выкрашивания;
– At installation of a blocking ring of the synchronizer on a cone of a corresponding gear wheel the backlash between end faces of a ring and a gear wreath of a gear wheel should be not less than 1 mm. Otherwise it is necessary to replace blocking ring.
33. Collect a secondary shaft in an order, the return to dismantling, taking into account the following:

– At напрессовке naves of synchronizers watch, that crackers have got to grooves of blocking rings;
– After assemblage of a secondary shaft check up rotation of all gear wheels: they should rotate freely.
