1. Warm up the engine. |
2. Uncover a head of cylinders and install the piston of the 1st cylinder in compression step VMT (see subsection 3.1.3). Valves of the cylinder have to rock freely. |
|
3. Measure by the probe gaps in the valves specified illustrations. The probe has to pass between a yoke and a core of the valve under small effort. |
|
4. If the gap differs from norm, then turn off a lock-nut and, rotating the screw-driver the screw, establish the necessary gap. |
5. Holding the screw the screw-driver, tighten a lock-nut and again check a gap. |
