Removal

PERFORMANCE ORDER
1. Uncover valves.
2. Remove the ignition distributor.
3. Remove covers of a gas-distributing belt, a belt and a camshaft asterisk.
4. Measure a free wheeling of a camshaft by means of the special device, if necessary replace a persistent plate of a camshaft, a camshaft and a head of cylinders.
Models in volume of 1,6 l
5. Before removal number all details.
6. Weaken bolts of yokes in the specified sequence (SOHC).
7. Remove axes of yokes together with yokes.
8. Remove the air filter and the block of fuses.
9. Get a camshaft from a head of cylinders. Take an epiploon.
Models in volume of 1,8 l
10. Unscrew bolts of asterisks of camshafts and remove asterisks.
11. Weaken bolts of covers of bearings in the specified sequence (1,8 l of DOHC). Remove covers.
12. Take into consideration an adjusting arrangement of epiploons.
13. Remove camshafts and epiploons.
14. Get hydraulic regulators of valves or pushers and combine them in the separate numbered boxes.

Check

PERFORMANCE ORDER
1. Examine all details on existence of scratches and damages.
Models in volume of 1,6 l
2. Examine the surface of yokes adjoining to cams of a camshaft on existence of strong wear and scratches. If necessary replace yokes.
3. Examine a surface of an axis of yokes and an internal surface of openings of yokes. Whenever possible measure diameter of openings of yokes and diameter of an axis of yokes.
4. Calculate a gap. If necessary replace axes and yokes.
5. Measure internal and external diameters of bearings of a camshaft and calculate a lubricant gap.
6. Measure camshaft cams.
Models in volume of 1,8 l
7. Check a lubricant gap of each bearing of a camshaft. Clean solvent bearings and covers of bearings. Establish shaft on places.
8. Put on each bearing a strip of measuring plastic.
9. Establish covers of bearings. Tighten bolts of covers in the specified sequence.
10. Unscrew bolts in the specified sequence and remove covers.
11. Compare width of the compressed strip to the measuring table.
12. If necessary replace a camshaft or a head of cylinders. Clean off the plastic remains.
13. Check hydraulic lifts of valves (1,8 l), if necessary replace them.
14. Measure external diameters of pushers or hydraulic lifts and diameters of their openings. If necessary replace worn-out details.
15. Examine cams and bearings of shaft.
16. Measure diameters of bearings of shaft. If necessary replace a shaft.
17. Measure height of each cam. If necessary replace a shaft.
18. Replace all details which characteristics do not correspond to technical requirements.
