2.3.10. Removal and installation of a bent shaft

Fig. 2.126. Components of a bent shaft: 1 – · m + to tighten a bolt of 65 N on 1/4 about. (90 °); 2 – bearing cover; 3 – · m + to tighten a bolt of 10 N on 1/4 about. (90 °); 4 – needle bearing; 5 – sensor gear wheel; 6 – bent shaft; 7 – adjusting washers; 8 – the bearing insert installed in the block of cylinders; 9 – asterisk; 10 – the bearing insert established in a bearing cover

NOTE For performance of adjusting works it is necessary to fix the engine by a katovatel at the adjusting stand.

Fig. 2.127. The scheme of installation of a bolt with a secret head

Replace a sensor 2 gear wheel after each untwisting of bolts of 1 (fig. 2.127).

NOTE After the second inhaling of a point of fastening of screws with a secret head in a gear wheel of the sensor it is deformed so strongly that heads of screws lie on cranked to a shaft 3 and cease to press a sensor gear wheel.

Installation of a gear wheel of the sensor is possible only in one situation, openings have to be displaced.

Inhaling moment:

– an engine speed sensor gear wheel to the crankshaft * – 10 N · m +90 ° **

Fig. 2.128. Accessory of inserts of the radical bearings installed in the block of cylinders

At the plant in the block of cylinders inserts of bearings of the correct thickness are established. For designation of thickness of inserts of bearings color marks serve.

NOTE The arrow specifies the direction of the movement.

What bearing should be used in a certain place, it is specified on the lower landing surface of the block of cylinders by alphabetic marking.

NOTE The inserts of radical bearings established in covers of bearings are delivered as the spare part only with "yellow" color marking.
