Opel Astra, Zafira

1. Disconnect a negative wire from the battery. Иммобилизуйте ignition system (the engine Electric equipment see the Head).
2. Make sure that transmission is translated in neutral position, then strongly cock a lay brake / prop up back wheels of the car противооткатными boots. Поддомкратьте car redock, establish it on props and remove the right forward wheel. At a corresponding complete set remove protection картера.
3. For the control of position of working ledges of cams uncover газораспределительного the mechanism. On l models 2.0 it is alternatively possible to dismantle the vacuum pump of the servo-driver of the brake amplifier (the Brake system see the Head). For the purpose of providing of access to a control aperture on a camshaft pin).
4. On models SOHC turn out fixing bolts and remove a pulley of a cranked shaft.

2. By means of the key which has been put on a bolt of fastening of a gear wheel / of an asterisk of a cranked shaft, turn last in a direction of normal rotation before combination adjusting risks of a gear wheel / of a pulley with a reciprocal label on the basis of a cover of the oil pump (model 1.7) / chains of drive ГРМ (l models 2.0 — address to an accompanying illustration). Combination of adjusting labels guarantees reduction in position ВМТ of pistons of the first and fourth cylinders.

   2 — the Adjusting label on a cover газораспределительной chains (model 2.0)
   3 — Risk on a pulley of a cranked shaft (model 2.0)

3. Now it is necessary to check up, what of pistons occupies ВМТ the end of a step of compression.

4. On engines 1.7 SOHC it is necessary to check up position of a cam of a drive of the final valve of the first cylinder (2 — extreme from outside drive ГРМ), — in position ВМТ of the end of a step of compression of the first cylinder the given cam is developed by a working ledge upwards. If a cam will develop a working ledge downwards, in ВМТ the end of a step of compression there is a piston of 4th cylinder and a cranked shaft it is necessary to turn on 360 ° in a normal direction.

5. On models 1.7 of l DOHC the conclusion in a demanded point of the piston of 1st cylinder is accompanied by combination adjusting рисок cogwheels of a camshaft and Fuel pump with carving fixing apertures in a head / the block of cylinders, except that, cams of a drive of both final valves of the first cylinder should be developed by working ledges upwards, — make sure, having glanced in маслозаливную a mouth. If risks of cogwheels appear developed concerning labels on 180 °, hence, in position ВМТ of the end of a step of compression there is a piston of 4th cylinder and for situation correction it is necessary to turn a cranked shaft in a normal direction for 360 °.

1. On engines of 2.0 l it is necessary to check up positions of cams, or a control aperture in an end face of a pin of a camshaft. In position ВМТ of the end of a step of compression of the piston of the first cylinder cams (1) drives of valves of the first cylinder should be developed by working ledges symmetrically upwards approximately under 45 ° to a vertical.

The control aperture in a shaft pin appears thus in position «at 12 o'clock». If shaft cams are developed by working ledges downwards, and the control aperture on a pin is in position «at 6 o'clock», in ВМТ the end of a step of compression there is a piston of 4th cylinder and a cranked shaft it is necessary to turn in a normal direction for 360 °.

3. Fixing of pistons in the chosen position on models 1.7 of l SOHC is made by blocking of a cranked shaft by means of the special adaptation KM-951 representing a core, entered into dredging in a gear wreath of a flywheel through an aperture in a transmission dome. At absence near at hand the special adaptation, it is possible to take advantage of a long bolt in diameter of 8 mm (is better for this purpose the bottom bolt of the steering column which end is ground on a cone will approach).

4. On models 1.7 DOHC fixing of pistons can be made at the expense of blocking of cogwheels of a camshaft and Fuel pump. Blocking of a cogwheel of a camshaft is carried out by means of bolt М6 passed in a round aperture in a spoke of a wheel and rolled in a carving aperture in a head of cylinders.

Cogwheel Fuel pump is blocked in a similar manner, with that only a difference that it is necessary to use bolt М8.

6. On l models 2.0 the cranked shaft can be blocked by adaptation KM-929 introduction in an aperture of the gauge of position of a shaft (CKP) in a forward part of the cylinder. In case of need suitable adaptation can be made own forces according to resulted on an illustration Dimensional characteristics of the adaptation for blocking of a cranked shaft (mm) in parametres. Remove gauge CKP and track that the adaptation core has entered into reciprocal cut in a shaft body.
