12. Operating in a similar manner, remove the right head of cylinders (a fixture reversing make in a mirror 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).
