The prevention

On the engine of 2,2 l before removal of camshafts it is necessary to remove a head of the block of cylinders preliminary.


PERFORMANCE ORDER
1. On the engine of 2,2 l merge cooling liquid from cooling system.
2. Remove the mechanism of a tension of a gear belt and pulleys of camshafts.
3. Unscrew bolts and remove internal casings of a gear belt.
4. Uncover heads of the block of cylinders.
5. Remove the camshaft gauge.
6. On the engine of 2,2 l, working from the centre to periphery, gradually and consistently ослабьте bolts of fastening of assemblage коромысел also remove it (fig. Elements of fastening of assemblage коромысел see).
7. Store assemblage коромысел so that apertures for a liquid have been directed upwards.
8. On the engine of 2,5 l gradually and consistently from edge to the centre unscrew bolts of fastening of covers of bearings of a camshaft (Elements of fastening of camshafts fig. see the engine 2,5).
9. Remove covers of bearings of a camshaft and take a camshaft from a head of the block of cylinders.
10. Store camshafts, covers of bearings and pushers so that could be established them on the places.
11. On the engine of 2,5 l take pushers from a head of the block of cylinders.
12. On the engine of 1,8 and 2,2 l remove a head of the block of cylinders. Uncover a forward sealing ring of a camshaft and take a camshaft from a head of the block of cylinders (fig. of the Detail of fastening of the left camshaft see the engine of 2,2 l, Details of fastening of the right camshaft on the engine 2,2).

Check

PERFORMANCE ORDER
1. On engines 2,2 with 1990 for 1996 remove hydraulic pushers with коромысел, and have them so that then they could be established on the places.
2. Check up degree of deterioration of hydraulic pushers.
3. Arrange hydraulic pushers in the pallet with engine oil.
4. Pressing on плунжер a pusher, check up, that its course did not exceed 0,5 mm, otherwise replace a hydraulic pusher.
5. Check up a condition of working surfaces коромысел. In the presence of considerable deterioration коромысла it is necessary to replace.
6. On the engine of 2,5 l check up a condition of hydraulic pushers on absence задиров and scratches.
7. Check up working surfaces of bearings the distributor th of shaft and contours of cams of camshafts on deterioration. In the presence of any deterioration replace a camshaft.
8. Using a micrometer, measure diameter of a neck of the bearing of a camshaft.
9. Using a micrometer, measure height of a cam of a camshaft.
10. Using a micrometer, measure diameter of the basis of a cam of a camshaft.
11. On the engine of 2,2 l measure internal diameter of bearings of a camshaft. If there is a considerable deterioration of internal bearings of a camshaft, it is necessary to replace a head of the block of cylinders.

Installation

PERFORMANCE ORDER
1. Grease necks of bearings and camshaft cams with pure engine oil.
2. On the engine of 2,2 l establish camshafts in heads of the block of cylinders. Establish forward covers of camshafts with new sealing rings.
3. Establish a new sealing ring of a camshaft and establish heads of the block of cylinders on the engine.
4. Establish assemblage коромысел on the engine and fix bolts.
5. A tightening of bolts make in the following sequence: preliminary tighten bolts 1–4, then tighten bolts 5–8 demanded moment and definitively tighten bolts 1–4 demanded moment (Sequence of a tightening of bolts of fastening of assemblage коромысел fig. see the engine 2,2).
6. On the engine of 2,5 l grease pushers with pure engine oil and establish them on the places.
7. Check up that adjusting washers are established in pushers.
8. Establish camshafts so that cams of camshafts have been directed aside, opposite to pushers.
9. On the engine of 2,5 l in order to avoid damages of valves in the course of installation it is necessary to establish camshafts under corresponding corners (fig. Corners of installation of camshafts see).
10. It is not required to turn camshafts of the right head of the block of cylinders for alignment of adjusting labels.
11. A camshaft operating inlet valves of the left head of the block of cylinders, it is necessary to turn on 80 clockwise, and a camshaft operating final valves of the left head of the block of cylinders, it is necessary to turn on 45 counter-clockwise.
12. Apply a thin film hermetic at installation of a forward cover of a camshaft.
13. Establish covers of bearings of camshafts and tighten their demanded moment in certain sequence (Sequence of a tightening of bolts of fastening of covers of a camshaft fig. see the engine 2,5).
14. Establish pulleys of camshafts and a gear belt. Check up and, if necessary, adjust backlashes of valves.
15. The further installation is made in sequence, return to removal.
