THE GENERAL DATA

Arrangement of bolts of fastening of the top directing chain


Removal

PERFORMANCE ORDER
1. Remove a wire of weight from the accumulator and a cover of a head of the block of cylinders.
2. Remove the vacuum pump of brake system.
3. Establish the piston of the first cylinder in the top dead point in a step of compression and fix a cranked shaft.
4. For access improvement to a cover of an asterisk of the fuel pump execute following actions:
– Remove a casing of the air filter and a forward exhaust pipe;
– Remove auxiliary приводной a belt;
– Unscrew a nut of fastening from a frame of a suspension bracket of the power unit and raise the engine so not to deform hoses and pipes.
5. Remove top натяжитель chains.
6. Remove the tension mechanism drive a belt.
7. Unscrew bolts and uncover asterisks of the fuel pump.
8. Put combination labels between the top chain and asterisks, and also between an asterisk of a camshaft and a camshaft.
9. Unscrew bolts and remove top directing to a chain.
10. Before unscrewing of bolts of fastening of the top directing chain bolts are necessary for heating up to soften the structure interfering unscrewing of bolts.
11. Using a wrench, fix a camshaft from проворачивания and unscrew bolts of fastening of an asterisk of a camshaft. Before bolt unscrewing take a pin of blocking of a cranked shaft and after bolt unscrewing establish a pin into place.
12. Remove a chain from an asterisk of a camshaft and take an asterisk from the engine. Under a chain establish a screw-driver or a steel core to prevent its falling in a head of the block of cylinders.
13. Pay attention to identification labels on covers of bearings of a camshaft. Covers are numbered from 1 to 5 from a forward part of the engine.
14. Working on a spiral outside inside, ослабьте covers of bearings of a camshaft on half of turn for each pass before full unscrewing of bolts. It is necessary for gradual and uniform removal of pressure клапанных springs. Remove covers of bearings of a camshaft.
15. Remove levers from the top part of a head of the block of cylinders and store them in the separate numbered packages.
16. For removal of hydraulic pushers remove a cross-section pipe of giving of fuel and, using a rubber sucker, or a magnet take hydraulic pushers and place them in the corresponding container.

Check

PERFORMANCE ORDER
1. Check up working surfaces of bearings of a camshaft and contours of cams on deterioration signs. In the presence of any deterioration the camshaft is subject to replacement.
2. Check up axial люфт a cranked shaft. If axial люфт exceeds admissible limits, the camshaft is subject to replacement.
3. Check up a condition of hydraulic pushers and nests for pushers in a head of the block of cylinders.

Installation

PERFORMANCE ORDER
1. Grease hydraulic pushers with pure engine oil and establish them on the places. Establish a cross-section pipe of an injector.
2. Establish levers of a camshaft labels () to a cross-section pipe of giving of fuel () in a head of the block of cylinders.
3. Grease camshaft levers with pure engine oil and establish a camshaft in a head of the block of cylinders. Thus cams of the first cylinder should be directed upwards, and the groove on the left end of a camshaft should be parallel to a surface of a head of the block of cylinders.
4. Check up that interfaced surfaces of covers of the bearing and a head of the block of cylinders, pure and dry and grease necks of a camshaft and cams with pure engine oil.
5. Apply a thin film hermetic on the top surface of a head of the block of the cylinders, interfaced to the left cover of the bearing of a camshaft and establish a cover.
6. Establish covers of bearings of a camshaft according to identification labels.
7. Tighten bolts of fastening of covers of bearings gradually and in certain sequence, turning each bolt on half of turn for one pass until each cover will not concern heads of the block of cylinders. Then in the same sequence tighten bolts in some stages the demanded moment. The gradual and uniform tightening of bolts is necessary for uniform compression of springs of the valve.
8. Using earlier put labels, check up that the top chain is correctly established on an asterisk of the fuel pump and dress a chain on a camshaft asterisk. Establish an asterisk on the end of a camshaft and establish a new bolt of fastening.
9. Establish top directing to a chain.
10. Using blocking pins, check up correctness of installation of the mechanism timing. Remove blocking pins.
11. Fix a camshaft from проворачивания and tighten in some stages a bolt of fastening of an asterisk of a camshaft (at the left – a tightening of a bolt the demanded moment, on the right – a bolt tightening доворачиванием it on a certain corner).
12. Establish top натяжитель chains.
13. Check up that interfaced surfaces of a cover of an asterisk of the fuel pump and a chain cover, pure and dry. Establish a cover of an asterisk of the fuel pump with a new lining or on a thin layer of hermetic and tighten bolts of fastening of a cover the demanded moment.
14. Establish the tension mechanism drive a belt.
15. Establish the right support of the power unit and lower the engine.
16. Establish a cover of a head of the block of cylinders.
17. Establish a forward exhaust pipe, a casing of the air filter and the gauge of a cranked shaft.
18. Establish the vacuum pump of brake system.
