Citroen Xantia

1. Achieve combination of apertures for blocking cranked/distributive shaft and ТНВД, pass in apertures metal cores of the corresponding diameter (Fixing cranked / distributive shaft and ТНВД for the purpose of prevention of casual hit of valves in contact to pistons in the course of performance of procedures of service of the car see). At all do not suppose attempts проворачивания the engine after introduction of blocking cores.
2. Remove covers газораспределительного a belt (Removal and installation of covers газораспределительного a belt see).
3. Remove a spherical receiver from the main hydraulic accumulator (the Uniform hydraulic system see the Head) and отболтите the bottom cover of transmission. Ask the assistant to block a gear wheel of a starter a screw-driver with a wide sting, then turn out a bolt of a pulley of a cranked shaft. Remove a pulley.
4. Remove a metal plate and an arm of the right support of the power unit (Removal and installation of components of the right support of the power unit and натяжителя газораспределительного a belt see), then ослабьте an axial nut and an adjusting bolt натяжителя газораспределительного a belt. For belt easing develop an arm натяжителя counter-clockwise. Again tighten an adjusting bolt, having fixed натяжитель in the given position. In case of need pass a 10-millimetric drive of a face key in the aperture of square section provided in an arm for the purpose of simplification of overcoming of resistance of a spring (Removal of a belt of drive ГРМ see an illustration).

5. Mark with an arrow an initial direction of rotation of a belt and remove last from the engine.

1. Make sure of presence on the place of 8-millimetric bolts blocking cogwheels of a camshaft and ТНВД, and also a core blocking a flywheel (Fixing cranked / distributive shaft and ТНВД for the purpose of prevention of casual hit of valves in contact to pistons in the course of performance of procedures of service of the car see).
2. Put on газораспределительный a belt a cogwheel of a cranked shaft, having tracked observance of an initial direction of its rotation.
3. Fix a belt on a wheel of a cranked shaft and accurately put on it the remained gear wheels/rollers in a following order (Removal of a belt of drive ГРМ see an illustration):
   a) the Intermediate roller;
   b) Cogwheel ТНВД;
   c) a camshaft Cogwheel;
   d) the Roller натяжителя;
   e) the Cogwheel of the water pump.

4. Try not to overwind and not to bend excessively at installation a belt. For a guarantee of correctness of landing of a belt plant it at first on half of width of cogwheel ТНВД, then get on a camshaft wheel, watching correctness of gearing of teeths on a wheel of a cranked shaft and without weakening a tape tightness. Having achieved desirable result, definitively plant a belt on all wheels.

5. Turn out fixing a camshaft and ТНВД bolts, take a core of blocking of a flywheel (Fixing cranked / distributive shaft and ТНВД for the purpose of prevention of casual hit of valves in contact to pistons in the course of performance of procedures of service of the car see).
6. At the released axial nut, manually keeping an arm натяжителя, ослабьте an adjusting bolt. Slowly release an arm so that the roller has nestled on an internal surface of a tape of a belt. Tighten an adjusting bolt and an axial nut.
7. Turn a cranked shaft on two complete revolutions in a normal direction (clockwise). Проворачивание a shaft it is in the opposite direction inadmissible, as the belt should remain tense on sites between cogwheels of a cranked shaft, ТНВД and a camshaft.
8. Loosen the adjusting and an axial nut a bolt натяжителя, having allowed a spring to press densely a roller to a belt tape, then tighten a bolt and a nut with demanded effort.
9. Make sure of correctness of combination of blocking apertures by продевания in them of cores of the corresponding diameter (Fixing cranked / distributive shaft and ТНВД for the purpose of prevention of casual hit of valves in contact to pistons in the course of performance of procedures of service of the car see). If to enter cores it is not possible, hence the belt is established incorrectly and all procedure is necessary for repeating.
10. The further assemblage is made in an order, the return to an order of dismantle of components.
