To fill in fresh engine oil in the case of a hydraulic pusher натяжителя chains, and applying the special adaptation 21-145 to collect натяжитель chains as follows. To establish the case of a pusher an aperture upwards. To establish the adaptation on the pusher case, and конусная the adaptation part should be directed upwards. To establish плунжер a pusher on the adaptation and to compress assemblage before weak click, thus the pusher should be fixed in the bottom position.

Check

To check up on deterioration and presence of damages a chain газораспределительного the mechanism, an asterisk and натяжитель chains. At deterioration of a plastic asterisk натяжителя chains, all knot натяжителя as separately asterisks are not delivered is subject to replacement.

Hydraulic pusher натяжителя chains

And – normal position плунжера, In and With – strong выступание the piston (the pusher is subject to replacement), 1 – a lock ring

Position of labels of installation of the asterisks, corresponding to installation of the piston of the cylinder 1 in the top dead point in a compression step


The special tool made of a wire in diameter of 2,5 mm for clearing плунжера of a pusher натяжителя of a chain

Installation

PERFORMANCE ORDER

1. To check up that the cranked shaft is in position corresponding to installation of the piston of the cylinder 1 in the top dead point in a compression step, thus шпоночный the groove should be directed downwards. 2. To lower a chain from above in a casing, thus a single copper link of a chain should be below. 3. To insert шпонку into a groove of a cranked shaft. 4. To establish a chain on an internal (big) asterisk having combined thus a copper link of a chain with a label on an asterisk. 5. To establish an asterisk on a cranked shaft, having combined a groove on an asterisk with шпонкой, thus the label on an asterisk should be strictly below. 6. To insert from above into place bottom успокоитель chains and to screw its bolts which carving is covered by the means interfering unscrewing of bolts. 7. To establish a hydraulic pusher натяжителя chains. Плунжер a pusher should be at level of the case or slightly act from it. At considerable выступании плунжера or a visible lock ring on плунжере the hydraulic pusher натяжителя to a chain is subject to replacement. 8. To establish the lever натяжителя chains, a lever axis натяжителя and to fix its lock washer. 9. To check up and if necessary to establish camshafts in a starting position. Camshafts should be in position corresponding to installation of the piston of the cylinder 1 in the top dead point in a compression step, and adjusting ledges for asterisks should be on one line with the top edge of a head of the block of cylinders and are directed outside. 10. To establish a chain on an asterisk of a final camshaft, having combined a label on an asterisk with the middle of a site of a chain between copper links of a chain. 11. To establish an asterisk on a camshaft. Thus the label on an asterisk (it is specified by an arrow) should be on one line with the top edge of a head of the block of cylinders and to be directed outside. 12. To screw a bolt of fastening of an asterisk. 13. To establish a chain on an asterisk of an inlet camshaft, having combined a label on an asterisk with the middle of a site of a chain between copper links of a chain. 14. To establish an asterisk on a camshaft. The prevention In an installation time of asterisks приводная the chain should be tense from an opposite side of the tension device. Thus the label on an asterisk should be on one line with the top edge of a head of the block of cylinders and to be directed outside. 15. To establish top directing to a chain газораспределительного the mechanism. 16. To turn a cranked shaft on some turns in a direction of working rotation of the engine. 17. To check up position плунжера a hydraulic pusher. If плунжер a pusher strongly acts from the case, to press it, having pressed the lever натяжителя chains. If плунжер a pusher is below level of the top edge of the case of a pusher, for clearing плунжера it is necessary to use the special tool made of a wire in diameter of 2,5 mm. 18. Cautiously to pick up the lever натяжителя, then to insert between the lever and плунжером the tool. To take a screw-driver and to release плунжер, having pressed the lever натяжителя chains and to take the tool. 19. To turn a cranked shaft on two turns in a direction of working rotation of the engine and to check up labels on asterisks of camshafts which should be on one line with the top edge of a head of the block of cylinders, and are directed outside. 20. To turn a cranked shaft on one turn in a direction of working rotation of the engine and to check up labels on asterisks of camshafts which should be on one line with the top edge of a head of the block of cylinders and are directed to each other. 21. To establish a chain of a drive of the oil pump on an asterisk of a cranked shaft, then to establish приводную an asterisk together with a chain on the oil pump. 22. To establish натяжитель chains of the oil pump. 23. To check up a condition of a sealing ring in the top cover of the distributive mechanism. If necessary to take an old sealing ring and using tubular оправку to establish a new ring the working edges directed to the engine. 24. To establish the top cover of the distributive mechanism with a new lining (fastening nuts are specified by arrows). 25. To establish a cover of a head of the block of cylinders. 26. To check up a condition of a sealing ring in the bottom cover of the distributive mechanism. If necessary to take an old sealing ring and, using tubular оправку, to establish a new ring the working edges directed to the engine. 27. To establish the bottom cover of the distributive mechanism with a new lining, without tightening fastening bolts. The ledge (it is specified by an arrow) on a lining should enter into a groove of the bottom cover. 28. To establish on a cranked shaft a pulley of an auxiliary belt and to fix its old bolt, simultaneously aligning the bottom cover of the distributive mechanism, and definitively to tighten bolts of fastening of a cover. 29. To unscrew from a pulley an old bolt and to screw in new, having tightened its demanded moment. 30. To establish the mechanism of a tension of an auxiliary belt, thus a ledge on a back part of the mechanism of a tension should enter into a corresponding aperture in the block of cylinders of the engine. 31.
