2.20. Check and adjustment of gaps in valves (except the M40 engine)


Valves are recommended to be regulated on the heated-up engine. Check of gaps is allowed and on the cold engine (see subsection 2.1).
1. Warm up the engine and uncover heads of cylinders (see subsection 3.1.5).
2. Establish the piston of the 1st cylinder in VMT of a step of compression (see subsection 3.1.4).
3. In this position of the crankshaft check gaps of valves of the 1st cylinder.
4. Gaps are measured in valves shchupy, laid between an end face of the valve and the adjusting clown of the corresponding yoke. Shchup should move under small effort.
5. In need of adjustment release a lock-nut and adjust a gap, turning the clown the piece of a thick wire inserted into its opening.
6. Holding the clown, tighten a lock-nut and again check a gap.
7. On M10 engines adjust other valves as 1–3–4–2. Turn the crankshaft on 180 ° clockwise and adjust valves of the 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 the 1st cylinder turn the crankshaft on 120 ° clockwise and adjust valves of the 5th cylinder. Repeat adjustment for valves of other cylinders.
9. Establish a cover of a head of cylinders, having replaced laying.
