Loosen the a tension of a belt of a drive of auxiliary units also give an intermediate gear wheel so that to release муфту натяжителя chains.
Turn out a stopper натяжителя, remove a spring and a pusher then remove натяжитель, without changing position of pistons.

Cover area round a chain on asterisks of camshafts rags and fix a chain plastic collars. Break off a chain, having removed by means of the special adaptation a folding link. Fix a plastic collar on the end of an old chain.
|
Connect a new chain to the old.
|
|
Do not suppose chain falling. Make sure that the new chain lies on an asterisk of an inlet camshaft. |
|

Ask the assistant to turn a cranked shaft (clockwise) and, keeping an old chain, stack a new chain on asterisks of a cranked shaft.
|
|
Hold an old chain strained that it has not developed on cranked to a shaft. |

Connect a new chain a connecting link, clean a collar and rags and stretch a chain so that this link has risen on the centre of the keeping adaptation.
Condense an aperture with rags, remove a connecting link and will put the new lock of a chain. Check up that the insert with number 2 is in the special adaptation, then place in it a plate of a connecting link and establish it on a link in a chain, having pressed with effort 10 Nm.
Turn an insert in the special adaptation and place its V-shaped dredging directly on one of шенкелей on a link. Rivet шенкель with effort 15 Nm. Then repeat this operation on other шенкеле.
Check up diameter compressed together шенкелей – it should make 3.4 - 3.6 mm.
Remove rags and keeping adaptation.
The further installation is made upside-down. Tighten fixture with demanded efforts. Use a new sealing ring натяжителя chains.
