Fig. 8.42. An arrangement of a template and a fixing arm for check axial люфта a secondary shaft

For adjustment axial люфта primary shaft use special a template and fixing arms (fig. 8.41, 8.42) or address for the help to specialists of specialized service station.

Installation axial люфта primary shaft carry out in the following order:

press a ring of the conic bearing in a coupling/differential case;

establish in a coupling/differential case primary shaft;

establish a case of a transmission and tighten bolts of its fastening the moment of 25 N · m;

having pressed primary shaft to a template a micrometer with a preliminary tightness, check value axial люфта (see fig. 8.41 );

proceeding from value axial люфта pick up the corresponding laying to provide demanded axial люфт primary shaft;

dismantle a case of a transmission and take primary shaft;

take an external ring of the bearing, establish the selected laying then again establish an external ring;

establish primary shaft;

establish a case of a transmission and tighten bolts of its fastening the moment of 25 N · m;

several times turn primary shaft to achieve exact installation of bearings;

repeatedly check axial люфт. The gap of the bearing should be within 0,01 — 0,12 mm.
