PERFORMANCE ORDER

1. To remove shatunno-piston group (see subsection 3.1.2.15).

2. To uncover epiploons of a cranked shaft with epiploons (see the item 2 of subsection 3.1.2.12) (a forward epiploon), subitem 1-2 of subsection 3.1.2.12) (a back epiploon).

3. To check marking on covers of radical bearings. If she is not visible, to mark covers number of the bearing.

4. To turn off bolts of 9 covers of radical bearings and to uncover 10 with inserts 8 (see rice. Cranked shaft and block of cylinders).

5. To remove a cranked shaft and to take out inserts 13 of beds of radical bearings and persistent half rings 1, previously having marked them number of the bearing.

6. To examine a cranked shaft. On working surfaces should not be having chopped off, zaboin, scratches, etc. Small scratches can be polished and then to zapolirovat. To measure diameters of a neck of shatunny and radical bearings. If they it is less nominal (the radical bearing of 57,96-57,98 mm, shatunny 45,96–45,98 mm), to pereshlifovat them under the repair size.

7. To establish inserts of 13 radical bearings in a bed so that the ledge of an insert entered dredging of a bed, and the opening for supply of oil in an insert coincided with an opening in a bed.

It is possible to take out the bearing a wire hook. To press the new bearing inscriptions outside, having drowned it on 1,5 mm from an end face of a cranked shaft.

14. To establish new epiploons of a cranked shaft.

15. To establish shatunno-piston group.
