2. Establish the piston of 1st cylinder in ВМТ a compression step (subsection 3.1.4 see).
3. In this position коленвала check up backlashes of valves of 1st cylinder.
4. Backlashes are measured in valves щупом, laid between an end face of the valve and the adjusting clown corresponding коромысла. Щуп should move under small effort.
5. In need of adjustment release a counternut and adjust a backlash, turning the clown the piece of a thick wire inserted into its aperture.
6. Keeping the clown, tighten a counternut and again check up a backlash.
7. On engines M10 adjust other valves as 1–3–4–2. Turn коленвал on 180 clockwise and adjust valves of 3rd cylinder. Repeat adjustment for valves of other cylinders.
8. On engines M20 and М30 valves are regulated as 1–5–3–6–2–4. After adjustment of valves of 1st cylinder turn коленвал on 120 clockwise and adjust valves of 5th cylinder. Repeat adjustment for valves of other cylinders.
