Klapannyj backlash


    Disconnect a negative cable from the accumulator. Uncover heads of cylinders, having addressed to Section the Cover of a head of cylinders in this Chapter.
    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.

    If клапанный the backlash does not correspond to technical characteristics, adjust it according to technical characteristics, turning the adjusting screw, preliminary having weakened a counternut. After adjustment fasten a counternut to the specified rotating moment, simultaneously keeping the adjusting screw motionlessly, and then be again convinced that клапанный the backlash corresponds to technical requirements.

Technical characteristics клапанного a backlash


When it is cold (antifreeze temperature makes 15 – 25С or 59 – 77F)

When hot (the antifreeze temperature makes 60 – 68С or 140 – 154F)

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).
1 — калибромер
    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.
    After check and adjustment of all valves, repeat dismantling procedure upside-down for the purpose of installation.
