Fig. 6.7. Adjustment of an emphasis of a lath: 1 — the screw of adjustment of an emphasis of a lath; 2 — a lock-nut; 3 — a lath emphasis; 4 — a lath

Remove the steering mechanism and establish its case in a vice with soft sponges. Turn out the adjusting screw of an emphasis of a lath (fig. 6.7), put on a carving part of the screw a layer of hermetic and again wrap the adjusting screw. Slightly wrap a lock-nut. Tighten the adjusting screw the moment of 5 — 6 N · m; turn out the adjusting screw, then tighten it the moment of 0,2 N · m.

Fig. 6.8. Measurement of the moment of rotation of a gear wheel of a lath: 1 — the Nissan KV48100700 adaptation; 2 — the Nissan ST3127S000 adaptation

Move several times a lath for all length of a course. Measure by means of a dinamometrichesky key (Nissan ST3127S000 adaptation) and an adapter (Nissan KV48100700 adaptation) (fig. 6.8) the moment of a provorachivaniye of a gear wheel of a lath. Establish a lath gear wheel in the point corresponding to the maximum measured moment. Release, then tighten the adjusting screw the moment of 4,9 N · m. Release the adjusting screw on 70 — 110 °. Tighten a lock-nut the set moment.
