6.3.11. Removal and TNVD installation
|
After installation it is necessary to pump over a power supply system, let's TNVD work without fuel (dry). |
Models with the M51 engine
|
- Disconnect a negative wire from the storage battery.
- Remove protection of a case of the engine.
- Remove the fan and its casing (see. Head of System of cooling of the engine, heating, ventilation and conditioning).
- Remove the inlet pipeline (see. Engine).
|
- Disconnect a hose (1) plum of oil, remove the drain pipeline (2) and disconnect топливопровод (4).
|
- By means of a special cutting key disconnect distributive pipelines from nozzles and from TNVD. Muffle open openings of nozzles and TNVD.
|
- Block the engine in position of the piston of the 1st cylinder in VMT of the end of a step of compression, having established for this purpose the adaptation No. 11 2 300. To make sure of correctness of VMT installation uncover a maslozalivny mouth: the cam of a camshaft should show up.
|
|
- Remove a kolpachkovy nut of a natyazhitel of a gear belt.
|
|
At installation check and if necessary replace a sealing ring. |
|
- Give the central nut and screw on its place the adaptation No. 13 5 120 without the pushing-out screw.
|
- Remove the channel of supply of air обдува the generator.
|
- Separate the socket on TNVD.
|
|
- Remove a dustproof cap and give a nut.
|
|
At installation pay attention to installation of prokladochny washers. |
- Rolling pushing-out screw in the adaptation No. 13 5 120, separate TNVD from an asterisk.
|
Leave screwed the adaptation No. 13 5 120 before the subsequent TNVD installation, differently the asterisk will fall, and the engine should be assorted. Before TNVD installation the pushing-out screw of the adaptation No. 13 5 120 should be turned out completely. |
|
- Turn TNVD clockwise so that the arm could be carried out by an arm of a support of the engine. Remove TNVD.
|
|
At installation replace a sealing ring of a flange of the pump. |
- Installation is made upside-down.
|
- Depending on TNVD support at installation under a landing opening in a support it is necessary to establish a prokladochny ring. If landing diameter (2) is equal 68 mm, clean a prokladochny ring (1).
|
- If TNVD is removed for the purpose of replacement, rearrange on the new pump assembly elements.
|
|
Models with the M57 engine
|
Close the generator from hit of working liquids on it. Situation TNVD concerning GRM does not render impact on its functioning. After a detachment of pressure head pipelines surely muffle openings in TNVD. |
|
- Remove the inlet pipeline (see. Head Engine).
- Lower OZh from a radiator of system of cooling (see. Head of Control and routine maintenance of the car).
|
- Turn out bolts (1), disconnect water hoses from a returnable tube (2) and remove it.
|
|
- Separate the socket (1) from a regulator of pressure of TNVD, weaken collars (3) and disconnect bringing and returnable fuel hoses (2).
|
|
At installation replace collars. |
|
- Separate the socket (2) glow plugs. Give cap nuts (1) fastening of the pipeline of the pump by means of the special adaptation No. 13 5 020 and remove the pipeline.
|
|
At installation pay attention to correctness of installation of the rezinometallichesky hinge (3). |
|
- Give nuts of fastening of TNVD and remove a belt of a drive of the generator from a roller of a natyazhitel (see. Head Engine).
|
|
- Turn out a carving stopper.
|
|
At installation replace a sealing ring. |
- Give a nut of fastening of an asterisk of a drive TNVD located under a carving stopper, and screw on its place the adaptation No. 13 5 192.
|
- Establish the adaptation No. 13 5 191 without a pushing-out bolt on TNVD asterisk then screw pushing-out bolt (1) at first to a dense prileganiye, and then so that TNVD will separate from an asterisk.
|
- Remove TNVD.
|
For asterisk fixing it is necessary to leave the adaptation No. 13 5 190 on the car and not to take out at all. |
- Installation is made upside-down. For TNVD installation of a high pressure turn out pushing-out screw. Clear interfaced surfaces and replace TNVD laying.
- After installation for air removal from a power supply system include ignition approximately for 1 minute. During this time the toplivopodkachivayushchy pump is activated, and the power supply system is filled with the fuel which is forcing out air.
|
|
Models with the M67 engine
|
If the established hoses of nadduvochny air are not fat-free also damp, it can lead to failure of the supercharger. After a detachment of pressure head pipelines surely muffle openings in TNVD. Situation TNVD concerning GRM does not render impact on its functioning. |
|
- Remove the top covers of the engine.
|
- Weaken a collar (1) and pull out a pressure head tube (2) of a pressure head hose.
|
- Remove a radiator casing (see. Head of System of cooling of the engine, heating, ventilation and conditioning).
- Lower cooling liquid from a radiator of system of cooling of the engine (see. Head of System of cooling of the engine, heating, ventilation and conditioning).
|
- Open clamps (1) water hose (2) and remove it.
|
|
- Give a cap nut (1) and slightly raise the pressure head pipeline (2).
|
|
- Weaken collars (1) and disconnect fuel hoses (2).
|
|
At installation replace collars of fastening of hoses. |
|
- Turn out bolts of fastening (1) TNVD and separate the socket of the valve of an otsechka from TNVD. Take aside a wire (2) and remove TNVD (3).
|
|
- Installation is made upside-down. Replace the damaged sealing ring of TNVD.
