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

Fig. 3.4. Installation piston end: And — orientation of rings at installation; B — cultivation of locks of piston rings; 1 — dredging has to be focused on the bottom of the piston towards the gas distribution mechanism drive; 2 — a joint of a spring dilator of an oil scraper ring; 3 — the lock of the top compression ring; 4 — the lock of the lower compression ring
