The mechanism of change of the moment of opening and closing of valves (CVVT) on engines of 1,8 and 2,0 l

Removal

 PERFORMANCE ORDER

    Remove the mechanism of an automatic tension of a chain.
    Remove covers of bearings of camshafts and a chain. Remove camshafts. Remove the mechanism of change of the moment of opening and closing of valves (CVVT). Fix in a vice гексагональную the part of a camshaft intended for a wrench.

Be cautious not to damage a camshaft. Turn out a bolt of fastening CVVT.

    Remove the oil regulating valve (OCV).
    Remove filter OCV. Remove the gauge of temperature of oil (OTS).

Check

Do not use repeatedly fallen mechanism of change of the moment of opening and closing of valves (CVVT) as thus it can be deformed.

  1. Do not assort the mechanism of change of the moment of opening and closing of valves (CVVT).
  2. At installation of the mechanism of change of the moment of opening and closing of valves (CVVT) it is necessary to use the special tool.

The mechanism of change of the moment of opening and closing of valves (CVVT)

 PERFORMANCE ORDER

    Fix in a vice гексагональную the part of a camshaft intended for a wrench. Be cautious not to damage a camshaft.
    Be convinced that the mechanism of change of the moment of opening and closing of valves (CVVT) is not turned on distributive to a shaft.
    With sticky tape stick all apertures of the mechanism of change of the moment of opening and closing of valves (CVVT), except one, designated by an arrow in drawing.
    To an aperture submit compressed air under the pressure of approximately 100 kPa.
    The mechanism of change of the moment of opening and closing of valves (CVVT) should turn without the appendix of external effort. Air giving under more high pressure can lead to blocking of a closing pin (absence of pressure).
    At performance of the action resulted in a step 4, a hand take the mechanism of change of the moment of opening and closing of valves (CVVT) and turn it in an advancing direction.
    After separation of a closing pin the mechanism of change of the moment of opening and closing of valves (CVVT) should move freely in an advancing direction. Moving of the mechanism of change of the moment of opening and closing of valves (CVVT) from the maximum position of delay before the maximum position of an advancing makes 20 .
    If necessary replace the mechanism of change of the moment of opening and closing of valves (CVVT), otherwise, turn it in a direction of delay before blocking of a closing pin.

The oil regulating valve (OCV)

 PERFORMANCE ORDER

    By ohmmeter measure internal resistance of the oil regulating valve (OCV). Resistance: 6,9 – 7,9 Ohm at temperature 20С. If resistance differs from demanded, replace the oil regulating valve. Check up working capacity of the oil regulating valve (OCV).
    Submit to plugs of the valve pressure from plugs of the storage battery: – be convinced that the coil moves in a direct direction. Disconnect wires from plugs of the storage battery: – be convinced that the coil comes back in a starting position.

Filter OCV

Check up a condition of the filter and absence in it of pollution. In the presence of pollution clear or replace the filter.

Camshaft (CVVT)

Height of cams of a camshaft of inlet valves: 44,618 mm
Height of cams of a camshaft of final valves: 44,518 mm
Is minimum admissible height of cams of a camshaft of inlet valves: 44,518 mm
Is minimum admissible height of cams of a camshaft of final valves: 44,418 mm

Installation

 PERFORMANCE ORDER

    Establish the gauge of temperature of oil (OTS). Establish filter OCV. The inhaling moment: 41–51 Nm.
  • At assemblage observe cleanliness. At repeated assemblage of the filter of the oil regulating valve (OCV) replace a washer.
    Establish the oil regulating valve (OCV). The moment of inhaling OCV: 10–12 Nm.
  • Repeatedly do not use the fallen details.
  • Exclude hit of extraneous impurity in plug OCV.
    Carefully insert a camshaft hairpin into an aperture of the mechanism of change of the moment of opening and closing of valves (CVVT).
    After installation CVVT on a camshaft screw a bolt, preliminary having oiled a bolt carving.
    Tighten a bolt of fastening CVVT on distributive to a shaft.
    Fix in a vice гексагональную the part of a camshaft intended for a wrench. Be cautious not to damage a camshaft. The moment of an inhaling of bolt CVVT: 66–78 Nm.
    Establish a chain on asterisks of camshafts how it is shown in drawing.
    Establish camshafts and covers of bearings.
    Establish the mechanism of an automatic tension of a chain. The inhaling moment: 8–10 Nm.
    Remove a stopper blocking the mechanism of an automatic tension of a chain.
