Fig. 3.2. Installation of covers of radical bearings of a cranked shaft and order of an inhaling of bolts of their fastening


Operations essentially do not differ from similar for petrol engines. Feature is removal of a belt of a camshaft, a belt of a drive of the fuel pump of a high pressure (TNVD) and TNVD; the listed operations are described in appropriate sections. Necessary explanations are given on fig. 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10.

Fig. 3.3. Installation of pistons in the block of cylinders: 1 — a label of dimensional group of the piston; 2 — a label of dimensional group of cylinders of the block


Fig. 3.4. Installation piston end: And — orientation of rings at installation; B — cultivation of locks of piston rings; 1 — dredging should be focused on the bottom of the piston towards a drive of the mechanism of a gazoraspredeleniye; 2 — a joint of a spring dilator of a maslosjemny ring; 3 — the lock of the top kompressionny ring;
4 — the lock of the bottom kompressionny ring


Fig. 3.5. Details of the block of cylinders and krivoshipno-shatunny mechanism: 1 — the top kompressionny ring; 2 — the bottom kompressionny ring; 3 — a maslosjemny ring; 4 — the piston; 5 — a piston finger; 6 — a lock ring; 7 — a rod; 8 — shatunny loose leaves; 9 — a cover of the bottom head of a rod; 10 — an arm; 11 — the block of cylinders; 12 — laying; 13 — the holder of a back epiploon of a cranked shaft; 14 — a back epiploon; 15 — a flywheel; 16 — a back cover of the block of cylinders; 17 — an opening stopper for plum of cooling liquid; 18 — the aligning plug; 19 — a cranked shaft;
20 — the loose leaf of the third support with persistent fillets; 21 — covers of radical bearings of a cranked shaft; 22 — the loose leaf of radical bearings of a cranked shaft


Fig. 3.6. Measurement of height of the block of cylinders


Fig. 3.7. Marking of dimensional groups of radical bearings of the block of cylinders


Fig. 3.8. Labels of dimensional groups of necks of a cranked shaft on the first counterbalance, considering from a drive of the mechanism of a gazoraspredeleniye:
1 — a code of dimensional group of diameters of shatunny necks of a cranked shaft; 2 — a label of dimensional group of diameter of a shatunny neck No. 1; 3 — a label of dimensional group of diameter of a radical neck No. 1; 4 — a code of dimensional group of diameters of radical necks of a cranked shaft


Fig. 3.9. Assembly of shatunno-piston group: 1 — cylinder number for a complete set of a rod and a cover of the bottom head (it should be focused towards the oil filter); 2 — an opening for greasing; 3 — a label of dimensional group of the piston (it should be focused towards a camshaft drive); 4 — the rod loose leaf with an opening for greasing; 5 — the loose leaf of a cover of the bottom head of a rod


Fig. 3.10. Measurement of diameter of the piston: And = 62 mm from the bottom
