REMOVAL
ATTENTION

Operations and the instructions existing concerning all engines, are given in the section for 4–цилидровых petrol engines. In the real subsection the differences relating to the diesel engine are described only.



PERFORMANCE ORDER
1. Remove maple a belt, address to the subsection Removal and installation of a maple belt.
2. Disconnect electric wires from the device of a stop and spark plugs.
3. Clear a cold cleaner топливопроводы at accessions of TNVD and disconnect them. Close openings caps.

Wipe a rag the flowed-out impellent oil. Disconnect pipelines of giving and oil return at a turbokompressor. Close pipelines polyethylene and rubber rings to exclude dirt hit.


4. Disconnect the pipeline of supply of oil to a turbokompressor at holders and the holder of the oil filter.
5. Unscrew bolts of fastening and remove the holder of a pipe of cooling liquid. Remove a pipe.

ATTENTION

Wipe a rag the flowed-out diesel fuel. Disconnect fuel hoses (shooters) of TNVD. Thus unclench pincers, for example, HAZET 798–5, collars. Close pipelines polyethylene and rubber rings for protection against dirt.


6. Rasstykuyte I will corrode – 2–sensors of pressure/temperature at a soaking-up pipe.
7. Disconnect a pipe of supply of air-1-from a head of cylinders.
8. Remove the top cover of a gear belt.
9. Unscrew two bolts of fastening of a cover of a gear belt behind from both parties of a head of cylinders.
10. Turn the engine in VMT and remove a gear belt from a camshaft pulley, address to subsection Installation of the piston of the first cylinder in VMT.
11. Remove a pulley of a gear belt of a camshaft, address to the subsection Removal and installation of a gear belt.
12. Completely unscrew a nut of a tension roller.
13. At the diesel engine bolts of fastening of a head of cylinders with internal shlitsa are established. Therefore their otvorachivaniye needs a special key, for example, HAZET 990 Sig–12. Unscrew bolts in sequence, their return numbering, that is with 10 on 1.
14. Take out by means of assistants a head of cylinders sideways from a protective casing of a gear belt and at the same time remove a tension roller.

INSTALLATION

PERFORMANCE ORDER
1. Heads of cylinders of the diesel engine to processing is not subject.
2. For a centering of a head of cylinders screw a screw-driver 3070 in external openings of bolts of fastening directing fingers of AUDI-3070/9. Instruction: If the specified fingers available are not present, instead of them old bolts of fastening of a head of cylinders with the cut-off heads can be used. For an otvorachivaniye of the fingers received thus it is recommended to make on a cut bottom under a screw-driver.
3. Depending on excess of pistons on thickness various laying of a head of cylinders is established. At replacement of laying pay attention to its marking and apply new laying only with the same marking. Arrow-1-: Number of the spare part, arrow-2-: an operating code (attention do not turn), an arrow-3-: = marking (openings).
4. If new pistons are established, check excess of pistons and according to it apply new laying (work HUNDRED).
5. Insert by means of the assistant a head of cylinders into a protective casing of a gear belt and at the same time put on a tension roller.

ATTENTION

At installation of a head of cylinders do not bend the heat-shielding screen of a final collector back ears of laying.


6. Bolts of fastening of a head of cylinders are tightened in four receptions in sequence with 1 on 10. The moments of an inhaling are given in Specifications.
