3.4.5. Check and adjustment of the mechanism of gas distribution

GENERAL INFORMATION

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

– instrument of blocking of the KM932 camshaft;
– pin of blocking of a ledge of the fuel pump KM927;
– pin of blocking of the bent shaft KM929;
– wrench of an asterisk of the KM933 camshaft.

Tools for adjustment of the mechanism of gas distribution


And – a pin of blocking of a bent shaft

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

With – the instrument of blocking of the camshaft

PERFORMANCE ORDER
1. Take off an auxiliary driving belt. Unscrew an auxiliary rack of a pulley of the mechanism of a tension, the lower bolt and a hinged bolt of a basic plate of a pulley and remove the tension mechanism.
2. Remove the vacuum pump of the brake system.
3. For improvement of access to a casing of an asterisk of the fuel pump and to the pump perform the following operations:

– 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 a head of the block of cylinders and install the piston of the first cylinder in the top dead point in a compression step.
5. Remove the sensor of a bent shaft.
6. Unscrew screws and remove a casing of an asterisk of the fuel pump from a chain casing.
7. Check that the tag of a pulley of a bent shaft is combined with the index and insert a pulley of blocking of a bent shaft into an opening of the sensor of a bent shaft and record a bent 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 a pump housing.
9. Insert a pin of blocking of the camshaft into an opening on the left end of the camshaft.
10. If all pins of blocking were established normally, so adjustment of the mechanism of gas distribution is not required. If at least one of pins of blocking is not established, it is necessary to make adjustment of the mechanism of gas distribution.
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 plunger, noting situation in which it is established.
13. Fix the camshaft from turning and unscrew a bolt of fastening of an asterisk of the 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 tag on the fuel pump. At the same time the top asterisk of a chain of the mechanism of gas distribution has to 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 required moment.
16. Establish a pin of blocking of the camshaft.
17. After installation of all pins of blocking put into place a camshaft asterisk, screwing up a bolt of fastening of an asterisk. At the same time support an asterisk so that sagging of a chain was from the chain tension mechanism.
18. Fix the camshaft from a provorachivaniye a wrench and in stages tighten a bolt of fastening of an asterisk of the camshaft the required 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 gas distribution. Insert a plunger into a head of the block of cylinders and tighten it the required moment.
20. Turn a bent shaft of the engine on two whole revolutions and check that all pins of blocking can be established.
21. Check that the interfaced surfaces of a casing of an asterisk of the fuel pump and a casing of a chain, pure and dry. Establish a casing of an asterisk of the fuel pump on laying or a layer of sealant and fix by bolts, having tightened them the required moment.
22. Install 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. Install the vacuum pump of the brake system.
26. Install the sensor of a bent shaft in the block of cylinders and connect the accumulator.
