10. Turn out the left two fixing bolts (2) and (4) and remove a head from the engine.
11. Remove sealing laying, - try not to damage the interfaced surfaces of a head and the block.
12. Working in a similar manner, remove the right head of cylinders (a reversing of fixture make in a mirror order).

Preparation for installation

 PERFORMANCE ORDER

1. Carefully smooth out and dry wipe the interfaced surfaces of a head and the block of cylinders. For removal of all traces of material of old laying and a deposit use a firm plastic or wooden scraper. Smooth out also the bottoms of pistons. Be extremely careful, - the surfaces made of soft metal can be damaged easily. Remember that dirt should not get to maslotok, water galleries and carving openings, - a zakuporta all open channels suitable traffic jams, or close up with an adhesive tape. For the purpose of prevention of hit of a deposit in gaps between pistons and cylinders, fill the last dense greasing which upon completion of procedure of cleaning will be easy to be removed with a rigid brush. Upon completion of cleaning wipe all surfaces pure dry rags.
2. Survey the interfaced surfaces of a head and the block on existence of deep scratches, cracks, cavities and other damages. Insignificant defects can be eliminated by means of a file with small tooth, in more serious cases the head should be given to a pro-point, or to replace.
3. Make sure of purity and dryness of carving openings, - just in case blow them compressed air (it is possible to use the bicycle pump). Presence at deaf openings of traces of greasing can lead to destruction of the block at a tightening of bolts as a result of increase of hydraulic pressure.
