20. If it is necessary to remove a gear wheel 2 from a bent shaft, at first remove the plug 1 and a rubber sealing ring between the plug and a gear wheel. Then press a gear wheel 2 by means of a stripper.
21. After removal wash out in gasoline of a chain and gear wheel, wipe and dry them.
22. Examine chains. If on plugs of a chain cracks, chips or considerable wear tracks were formed, replace chains.
23. Replace gear wheels which on teeths have chips or a vykrashivaniye.
24. The damaged uspokoitel of chains replace.
25. Asterisks of natyazhitel have to rotate freely on axes. If on teeths of asterisks there are chips or a vykrashivaniye, replace natyazhitel.
26. If removed a gear wheel from a bent shaft, its napressuyta on a bent shaft, establish a sealing ring and the plug.
27. Turn a bent shaft so that the tag 1 on a gear wheel of a bent shaft coincided with a tag 2 on the block of cylinders. At the same time the piston of the 1st cylinder will reach VMT position. Establish an uspokoitel of a chain 4, but do not tighten bolts 3 fastenings of an uspokoitel. Put on a chain 5 a gear wheel of a bent shaft, previously having oiled it engine.
28. Put on a chain the conducted gear wheel 1 and establish it on an intermediate shaft 2 so that the adjusting pin of a gear wheel entered an opening of an intermediate shaft. At the same time the tag 4 on a gear wheel has to coincide with a tag 5 on the block of cylinders, and the chain branch passing through an uspokoitel 3 has to be tense.
29. Establish the leading gear wheel of an intermediate shaft so that its adjusting pin entered an opening on the conducted gear wheel.
30. Screw two bolts of fastening of gear wheels of an intermediate shaft, having enclosed under them a lock plate. Tighten bolts the moment of 22-25 N · m (2,2–2,5 kgfs · l) also record them, having bent edges of a lock plate on the verge of heads of bolts.
31. Having pressed the lever of a natyazhitel, pull a chain and check coincidence of tags on gear wheels and the block of cylinders.
32. Tighten bolts of fastening of an uspokoitel of a chain.
33. Oil the top chain engine and then put on it the leading gear wheel of an intermediate shaft, having passed in an opening in a head of the block of cylinders.
34. Put on a chain a gear wheel 2 and, having slightly turned the final camshaft clockwise, establish on it a gear wheel 2 with the chain which is put on it. At the same time the pin of the 8th camshaft has to enter a gear wheel opening. Screw a bolt 1. It is necessary to turn the camshaft a key for a tetrahedron on it. Then, having slightly turned the camshaft counterclockwise, pull a chain. Intermediate and cranked shaft at the same time should not turn. The tag And has to coincide with the top plane of a head of the block of the cylinder. Turn out a bolt 6 and remove a gear wheel 4 from the inlet camshaft. Put on the 4th chain a gear wheel and install a gear wheel 4 with a chain on the camshaft, having slightly turned the camshaft clockwise. The pin of the 5th camshaft has to enter a gear wheel opening. Having slightly turned the camshaft counterclockwise, pull a chain. The tag And on a gear wheel 4 has to coincide with the top plane of a head of the block of cylinders. Other shaft at the same time should not turn. Screw a bolt 6. Tighten bolts the 1 and 6 moment of 46-74 N · m (4,6–7,4 kgfs · l), holding camshafts from a provorachivaniye a key for tetrahedrons. Establish an uspokoitel 3, having pushed it in an opening in a block head. Establish an uspokoitel 7.
35. Establish a cover of a chain and the water pump. At the same time apply on the cover surface adjacent to the block of cylinders and a head of the block, a thin layer of Germesil sealant or its analog. At installation of a cover of a chain track to damaging an epiploon of a bent shaft.
36. Establish gidronatyazhitel of the top and lower chains, see. "Assembly ("charging") and installation of gidronatyazhitel of chains". Establish a pulley of a bent shaft. Screw a bolt of fastening of a pulley of a bent shaft and tighten the moment 104–128 N · m (10,4–12,8 kgfs · l), holding a bent shaft from a provorachivaniye, having included the IV transfer and having slowed down the car the parking brake. At a ratchet inhaling the pulley napressovyvatsya on a bent shaft.
37. Turn for a ratchet a bent shaft on two turns and install the piston of the 1st cylinder in the provision of VMT (see. "Installation of the piston of the first cylinder in the provision of VMT of a step of compression"). Check coincidence of tags.
38. Establish a forward cover of a head of the block of cylinders for what apply on the cover surface adjacent to a block head, a layer of Germesil sealant. Tighten bolts of fastening of a cover the moment of 12-18 N · m (1,2–1,8 kgfs · м).
39. Establish a cover of a head of the block of cylinders. Tighten bolts of fastening of a cover the moment of 6,0-12 N · m (0,6–1,2 kgfs · м). Connect a hose and a tube of ventilation of a case to unions on a cover of valves and wires to ignition coils. Put on tips of high-voltage wires spark plugs.
40. Install the removed earlier hinged units.
