Removal and TNVD installation

Try not to allow dirt hits in the pump! At assembly new sealing rings of hollow bolts of shtutserny connections of fuel lines will be necessary.

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. Cover with polyethylene the generator in order to avoid diesel fuel hit on it. On the models equipped with the conditioner of air, remove the generator with an assembly bracket (see. Preheat system - diesel models), and also a belt of a drive of auxiliary units.
3. For the purpose of ensuring access, remove an air distributor casing. In case of need remove also inlet air line and disconnect a ventilating branch pipe from a jellied mouth of impellent oil. For more details see appropriate sections of the present Chapter.
4. On models from RKPP prop up protivootkatny boots back wheels, then поддомкратьте the right forward corner of the car so that the wheel completely came off the earth. Establish the lifted car on a prop and include the 4th or 5th transfer easily to turn the engine for the right forward wheel. On models from AT the engine should be turned a wrench for a bolt of a pulley of a cranked shaft (for the purpose of decrease in resistance turn out glow plugs).
5. Remove the top cover (and) a gas-distributing belt (see. Head engine Repair).
6. At the corresponding complete set disconnect hoses from the vacuum converter at TNVD end face.

7. Disconnect from the pump a gas cable - see. Removal, installation and adjustment of a cable of gas. On models from AT disconnect also a cable of inclusion of the kick-down mode (see. Automatic transmission).

8. Also disconnect from the pump a driving cable of fast idling (see. Removal, installation and adjustment of the thermosensitive sensor of turns of fast idling).

9. Release a collar / give the shtutserny socket and disconnect a hose of supply of fuel. At the corresponding complete set, remove sealing washers of a hollow bolt of the shtutserny socket. At once закупорьте the open end of the hose/union also screw into place a hollow bolt of shtutserny connection in order to avoid hit in dirt system.



10. Disconnect the main tube of return of fuel and отстыкуйте the shtutserny socket of a tube of return of fuel from injectors. Remove sealing washers of a hollow bolt of the shtutserny socket. Do not forget to cork the open end hoses and to screw into place a bolt of shtutserny knot (do not mix inlet and final shtutserny connections).

11. Disconnect from the pump the corresponding electroconducting. Pay attention that on some pumps of Bosch system rather simply расстыковать contact sockets on a pump arm. On other pumps it is necessary to disconnect electroconducting from separate components (some contact connections are protected by rubber caps).

12. Give cap nuts of shtutserny connections of fastening of fuel tubes to TNVD and nozzles. The second half of the socket at an otdavaniye of a cap nut should be held an additional key.



13. Remove tubes in a set.

14. At once закупорьте the open ends of shtutserny sockets in order to avoid hit in dirt system (it is possible to use the fingers cut off from rubber gloves).

15. Turn a cranked shaft so that two boltovy openings in a cogwheel of TNVD were combined with reciprocal openings in a forward plate of the engine.

16. Pass in the combined openings two bolts М8 and strongly tighten them. Pay attention that bolts should hold a cogwheel in the course of pump removal that allows to avoid need of removal of a gas-distributing belt.

17. Mark position of the pump in relation to a basic arm.

18. Give three lobbies fixing nuts, remove washers.

19. Give a back nut, take a bolt (pay attention to an arrangement of washers). Prop up TNVD assembly by wooden whetstone.

20. Remove TNVD cogwheel from a pin of a shaft of the pump (see. The repair procedures which are not demanding extraction of the engine from the car - diesel engines). Pay attention that the cogwheel can be not taken out from a belt. For wheel fixing after removal of the pump use two bolts М8.

21. Accurately remove the pump. Take from the groove on a pin of a shaft of the pump a segment shponka (if it is planted freely).

22. The same do with the plug in a back part of a basic arm. Clean the removed components in a reliable place.

Installation

 PERFORMANCE ORDER

1. If removed, plant in the groove not to a pin of a shaft of the pump a segment shponka.
2. Place the pump on a basic arm and prop up it wooden whetstone.
3. Put on a cogwheel a pin of a shaft of TNVD (see. Removal and installation of cogwheels of a belt of a drive of GRM of a part the Repair procedures which are not demanding extraction of the engine from the car - diesel engines). Try not to allow losses of a segment shponka.
4. Achieve combination of the landing labels put in the course of dismantle. If the new pump is established, for approximate installation transfer on it a label with removed from the engine.
5. Freely screw pump fixture.
6. Make installation of phases of a gazoraspredeleniye (see. Methods of check of installation of the moments of injection of fuel, Check and adjustment of the moments of injection (TNVD Lucas) and Check and adjustment of the moments of injection (TNVD Bosch)).
7. Connect fuel tubes of nozzles.
8. Connect to the pump electroconducting.
9. Connect tubes of giving and fuel return, correctly having tightened their shtutserny sockets (do not forget to replace sealing washers of hollow bolts).
10. Connect a driving cable of fast idling (see. Removal, installation and adjustment of the thermosensitive sensor of turns of fast idling).
11. Connect and adjust a gas cable (see. Removal, installation and adjustment of a cable of gas). At the corresponding complete set connect a cable of inclusion of the kick-down mode (see. Automatic transmission).
12. Where it is required, connect hoses to the vacuum converter.
13. Establish the top cover (and) a gas-distributing belt.
14. Lower the car on the earth.
15. Where it is required, establish into place an air distributor cover.
16. Remove polyethylene from the generator. On the models equipped To/in, establish the generator with an assembly bracket and a belt of a drive of auxiliary units (see. Start and charge systems).
17. Connect a negative wire to the battery.
18. Remove air from a power supply system (see. Power supply system filling with fuel and removal from it air jams).
19. Start the engine and check correctness of adjustments of TNVD (address to Head Routine maintenance).
