Removal and installation of heads of cylinders

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. Remove camshafts (see Has undressed Removal and installation of camshafts).

8. Operating strictly in a certain order), in regular intervals ослабьте also turn out bolts of fastening of a head of cylinders.

 Bolts (2) and (4) leave wrapped on three-four coils for the purpose of head fixing at last stage.

9. Обстучав on perimetre a hammer with soft brisk, separate a head from the block of cylinders.
10. Turn out the left two fixing bolts (2) and (4) and remove a head from the engine.
11. Remove a sealing lining, - try not to damage interfaced surfaces of a head and the block.
12. Operating in a similar manner, remove the right head of cylinders (a fixture reversing make in a mirror order).

Preparation for installation

 PERFORMANCE ORDER

1. Carefully smooth out and dry wipe interfaced surfaces of a head and the block of cylinders. For removal of all traces of a material of an old lining and a deposit use a firm plastic or wooden scraper. Smooth out also the bottoms of pistons. Be extremely cautious, - the surfaces made of soft metal can be damaged easily. Remember that the dirt should not get in маслотоки, water galleries and carving apertures, - закупорьте all open channels suitable stoppers, or close up with an adhesive tape. For the purpose of prevention of hit of a deposit in backlashes between pistons and cylinders, fill the last dense greasing which on termination of clearing procedure will be easy for removing a rigid brush. On termination of cleaning wipe all surfaces pure dry rags.
2. Survey interfaced surfaces of a head and the block on presence of deep scratches, cracks, cavities and other damages. Insignificant defects can be eliminated by means of a file with a small tooth, in more serious cases it is necessary to give a head in проточку, or to replace.
3. Make sure of cleanliness and dryness of carving apertures, - just in case blow their compressed air (it is possible to take advantage of the bicycle pump). Presence at deaf apertures of traces of greasing can lead to block destruction at a tightening of bolts as a result of increase of hydraulic pressure.
4. By means of a steel ruler and probeа лезвийного type check up planeness of an interfaced surface of a head (see Has undressed Service of a head of cylinders of the present Chapter).

INSTALLATION

 PERFORMANCE ORDER

1. Having replaced a sealing lining, establish a head of cylinders on the regular place on the block.
