Using 17 mm the plug, turn a pulley of a cranked shaft (1) clockwise while the mark V (a white paint) (2) on a pulley will not be made even to "the 0" (zero) calibrated on a cover of a belt of a drive газораспределительного of the mechanism.

Check up, whether are коромысла valves of the cylinder №1 out of corresponding contours of a cam (cam-shaft); if it so, valves (1), (2), (5) and (7) in drawing are ready to check and backlash adjustment. Check up клапанные backlashes on valves (1), (2), (5) and (7). If коромысла valves of the cylinder №4 are out of corresponding contours of a cam, check up клапанные backlashes on valves (3), (4), (6) and (8).

At check клапанного a backlash insert калибромер between a cam-shaft and a working surface of a cam коромысла the valve.

On an input

0.13 – 0.17 mm (0.005 – 0.006 inches)

0.17 – 0.21 mm (0.007 – 0.008 inches)

On an exit

0.23 – 0.27 mm (0.009 – 0.010 inches)

0.28 – 0.32 mm (0.011 – 0.012 inches)

Special инструмент6 () — 09917-18211. The rotating moment of an inhaling: a counternut of the adjusting screw коромысла the valve () — 12 Н•м (1.2 kg th, 9.0 pound on foot).

After check and adjustment клапанных backlashes on valves (1), (2), (5) and (7), (or (3), (4), (6) and (8)) turn коленвал precisely on 360 degrees (one complete revolution) and check up too most on valves (3), (4), (6) and (8) (or (1), (2), (5) and (7)).

Adjust them as it is necessary.
