REMOVAL

 PERFORMANCE ORDER

1. Remove a pulley of a cranked shaft (see Has undressed Removal and installation of a pulley of a cranked shaft).
2. Remove a forward cover of drive ГРМ (see Has undressed Removal and installation of covers of drive ГРМ).
3. Remove газораспределительную a chain (see Has undressed Removal and installation газораспределительных chains).
4. Remove asterisks of camshafts (see Has undressed Removal and installation of asterisks of a drive of camshafts).
5. Remove an asterisk of a cranked shaft (see Has undressed Removal and installation of an asterisk of a cranked shaft).
6. Remove a back cover of drive ГРМ (see Has undressed Removal and installation of covers of drive ГРМ).

7. Uncover the right head of cylinders.

8. Operating in ascending order serial numbers, in regular intervals ослабьте also turn out bolts of fastening of a forward cover of camshafts of the right head.

9. Operating in ascending order serial numbers, in regular intervals ослабьте also turn out bolts of fastening of covers of bearings of camshafts.

10. Having removed covers of bearings, take at first inlet, then final camshafts.

11. Take заглушки from a cover of the left head of cylinders.

12. Operating in the similar manner described above, remove camshafts of the left head (fixture release in a mirror order).

CHECK

 PERFORMANCE ORDER

1. Measure size of radial palpation of a camshaft (see Has undressed Removal and installation of camshafts). In case of need make necessary regenerative repair, or replace a shaft.
2. Check up подшипниковые shaft necks on presence of signs of excessive deterioration and mechanical damages. The defective shaft is subject to replacement.

3. Measure external diameters of necks. In case of a deviation of results of measurements from the values resulted in Specifications, make definition of working backlashes in bearings by means of the calibrated plastic thread (set Plastigage):

· Carefully wipe basic surfaces of covers and a shaft neck;
· Lay a shaft on the regular place in a head of cylinders;
· Place lengthways подшипниковых necks pieces of the calibrated plastic thread from set Plastigage;
· Establish covers of bearings and tighten bolts of their fastening with demanded effort (see more low).

 Do not turn a shaft in the course of measurement of backlashes!

· Remove covers and, having measured width of as much as possible flattened out sites of pieces of threads on put on packing of a set to a scale, define sizes of working backlashes in bearings;
· Carefully clear necks and beds of bearings in covers of the rests of the flattened out threads from a set.

4. Estimate a condition of working surfaces of cams of a shaft. Minor defects can be eliminated by means of an emery paper.
5. Check up geometrical parametres of cams of camshafts (see Has undressed Removal and installation of camshafts). Compare results of measurements to requirements of Specifications, in case of need replace a shaft.
6. With the help циферблатного a measuring instrument плунжерного type define size axial люфта camshafts (see Has undressed Removal and installation of camshafts). Compare results of measurements to requirements of Specifications, in case of need replace a shaft or a head complete with covers of bearings.

INSTALLATION

 PERFORMANCE ORDER

1. Having greased подшипниковые necks with impellent oil, establish camshafts on the regular places. Attention: Track correctness of placing of pins in forward flanges of shaft, - at 10 o'clock for shaft of the right head and at 12 o'clock for shaft of the left head.

And — Pins of forward flanges

2. Put a few hermetic of type Three Bond 1280В (a pillow in diameter 2.0 ± 0.5 mm in section) on interfaced surfaces of a back part of forward covers of camshafts.

 Drawing of excessive quantity of hermetic is fraught with development of leaks of oil as a result of epiploon pollution.

3. Having greased interfaced surfaces with impellent oil, establish covers of bearings of camshafts, then, moving to strictly certain order, tighten bolts of fastening of covers with demanded effort (16 Nanometers).

4. Operating in an order, the return shown on an illustration, tighten bolts of fastening of forward covers of camshafts with demanded effort (9.8 Nanometers).

5. According to the scheme presented on an illustration, put a few hermetic of type Three Bond 1280В on interfaced surfaces of heads of cylinders and their covers.

 Drawing of excessive quantity of hermetic is fraught with development of leaks of oil as a result of epiploon pollution.

6. Operating strictly in a certain order, tighten bolts of fastening of a cover of a head of cylinders with demanded effort (6.4 Nanometers).

7. The further installation is made in an order, the return to an order of dismantle of components.
