3.4.5. Check and adjustment of the mechanism of a gazoraspredeleniye

GENERAL INFORMATION

To check installation of the mechanism of a gazoraspredeleniye and the fuel pump it is necessary to use special tools:

– instrument of blocking of camshaft КМ932;
– pin of blocking of a ledge of the fuel pump KM927;
– pin of blocking of cranked shaft КМ929;
– wrench of an asterisk of camshaft КМ933.

Tools for adjustment of the mechanism of a gazoraspredeleniye


And – a pin of blocking of a cranked shaft

In – a pin of blocking of a ledge of the fuel pump

With – the instrument of blocking of a camshaft

PERFORMANCE ORDER
1. Remove an auxiliary driving belt. Unscrew an auxiliary rack of a pulley of the mechanism of a tension, the bottom bolt and a sharnirny bolt of a basic plate of a pulley and remove the tension mechanism.
2. Remove the vacuum pump of brake system.
3. For improvement of access to a casing of an asterisk of the fuel pump and to the pump execute the following actions:

– remove a casing of the air filter and a reception exhaust pipe;
– unscrew a nut from the top part of the right support of the power unit and lift the right side of the engine on as much as possible.
4. Uncover heads of the block of cylinders and establish the piston of the first cylinder in the top dead point in a compression step.
5. Remove the sensor of a cranked shaft.
6. Unscrew screws and remove a casing of an asterisk of the fuel pump from a chain casing.
7. Check that the label of a pulley of a cranked shaft is combined with the index and insert a pulley of blocking of a cranked shaft into an opening of the sensor of a cranked shaft and fix a cranked shaft from a provorachivaniye.
8. Insert a pin of blocking of a ledge of the fuel pump into an opening in a ledge and, moving a pulley, insert it into an opening in the pump case.
9. Insert a pin of blocking of a camshaft into an opening on the left end of a camshaft.
10. If all pins of blocking were established normally, means, adjustment of the mechanism of a gazoraspredeleniye is not required. If though one of pins of blocking is not established, it is necessary to make adjustment of the mechanism of a gazoraspredeleniye.
11. Take a pin of blocking of the pump and take a bolt on the right side of a suspension bracket from a head of the block of cylinders.
12. Unscrew the top head of a natyazhitel of a chain and take a plunzher, noting situation in which it is established.
13. Fix a camshaft from turning and unscrew a bolt of fastening of an asterisk of a camshaft. Establish a new bolt, having tightened it by hand.
14. Weaken the bolts, fixing an asterisk of the fuel pump to a pump ledge.
15. Check the provision of an adjusting label on the fuel pump. Thus the top asterisk of a chain of the mechanism of a gazoraspredeleniye should be combined with a pump ledge. Insert a pin of blocking of a ledge of the fuel pump and tighten bolts of fastening of an asterisk the demanded moment.
16. Establish a pin of blocking of a camshaft.
17. After installation of all pins of blocking plant into place a camshaft asterisk, screwing up a bolt of fastening of an asterisk. Thus support an asterisk so that sagging of a chain was from the mechanism of a tension of a chain.
18. Fix a camshaft from a provorachivaniye a wrench and in stages tighten a bolt of fastening of an asterisk of a camshaft the demanded moment.
19. Take all pins of blocking, establish a new sealing ring to the top head of a natyazhitel of a chain of the mechanism of a gazoraspredeleniye. Insert a plunzher into a head of the block of cylinders and tighten it the demanded moment.
20. Turn a cranked shaft of the engine on two complete revolutions and check that all pins of blocking can be established.
21. Check that interfaced surfaces of a casing of an asterisk of the fuel pump and a chain casing, pure and dry. Establish a casing of an asterisk of the fuel pump on laying or a layer of hermetic and fix bolts, having tightened them the demanded moment.
22. Establish the tension mechanism.
23. Establish a support of the power unit. Establish a cover of a head of the block of cylinders.
24. Establish a reception exhaust pipe and a casing of the air filter.
25. Establish the vacuum pump of brake system.
26. Establish the sensor of a cranked shaft in the block of cylinders and connect the accumulator.
