Check and adjust the valve clearance
NOTE Check and adjustment of backlashes in a drive of valves is made on a cold engine (coolant temperature: 20 ?� C and mounted on the engine cylinder head. |
Remove the soundproofing engine cover. Remove the oil filler cap. Remove the bolts from the center of the cover and then remove the cover.
Unscrew the top of the timing belt cover and then remove the cover. Remove the cylinder head cover. Disconnect the spark plug wires high voltage holding them for caps and not making significant efforts when they disconnect.
NOTE Stretching or bending of the high voltage can damage the conductor inside the wire. |
Disconnect the PCV hose and breather hose PCV valve from the cylinder head cover. Disconnect the cable of the accelerator pedal from the cylinder head cover. Unscrew the cylinder head cover and then remove the cover and gasket.

Install the piston cylinder ?��1 at TDC compression stroke (Fig. 2.102). Rotate the crankshaft pulley and align it with the notch on the timing mark "T" on the display timing of injection (scale on the bottom cover the timing belt).
| Fig. 2.103. The combination of the camshaft sprocket with the timing mark on the cover of the front bearing
|
Check that the hole in the sprocket (belt) of the camshaft is aligned with the mounting mark on the cover of the front camshaft bearing. If the alignment is not present, turn the crankshaft one revolution (360 ?�) (Fig. 2.103). Check the valve clearance. Check only checked the figure valves (the cylinder when the piston is at TDC compression ?��1). Measure the valve clearance. With feeler gauge, measure the clearance between the shim plunger and the back surface (non-working) of the cam. Record the results of measurements of the gap in areas where the measured value does not correspond to a valid value. These data continue to be needed for the selection of a replaceable shim. Values valve clearance (when the engine coolant temperature: 20 ?� C) are shown below. Nominal value: the intake valves - 0.20 mm; exhaust valves - 0.28 mm. Limit: the intake valves - 0,12-0,28 mm; exhaust valves - 0,20-0,36 mm.
Adjusting valve clearance when the piston cylinder ?��1 at TDC compression stroke Rotate the crankshaft pulley one turn (360 ?�) and align it with the notch on the timing mark "T" on the display timing of injection (scale on the bottom cover the timing belt).

Adjusting valve clearance when the piston cylinder ?��4 at TDC compression stroke Adjustment of backlashes in a drive of the intake and exhaust valves.
Rotate the crankshaft to the valve, the actuator which is controlled by the gap, the protruding part of the cam camshaft points upwards (Fig. 2.106).
| Fig. 2.107. Install the stopper between the camshaft and the valve tappet
|
With the help of special tools 09220-2D000 click on the valve lifter and insert the stopper between the camshaft and tappets. Remove the special tool (Fig. 2.107).
Using a micrometer, measure the thickness of the removed shim (Fig. 2.109). Calculate the thickness of the new shim which must be installed in order to play in the valve drive according to the nominal value.
Valve clearance (when the engine coolant temperature: 20 ?� C) T: Thickness of installed shim A: The measured valve clearance in the drive. N: The thickness of the new shim. The inlet valve: N = T + (A-0,20) mm. Discharge valve: N = T + (A-0.28) mm. Pick a new shim thickness, as close as possible to the calculated value.
NOTE There are 20 different sizes of shims plunger in increments of 0.04 mm in the range from 2.0 mm to 2.76 mm. |
Install selected shim on the valve tappet. With the help of special tools 09220-2D000 press the plunger valve and remove the stopper. Recheck the backlash in the valve actuator.
Setting Remove the remnants of the old lining and hermetic to the gasket face of the cylinder head and cylinder head cover.
| Fig. 2.110. Places applying sealant to the cylinder head cover
|
Apply sealant (Loctite ?�� 5999) on the cylinder head cover (Fig. 2.110). Install the cylinder head cover. Tightening torque bolts cylinder head cover: 8-10 Nm. Connect the cable of the accelerator pedal. Connect the PCV hose and breather hose PCV valve to the cylinder head cover. Connect spark plug wires high voltage to the spark plugs. Install the upper timing belt cover and tighten the four bolts. Install the center cover and tighten the five bolts. Torque the bolts holding the center cover: 2.5-3.5 Nm. Install the oil filler cap. Install soundproofing engine cover.
Timing chain guide
Check the chain guide in the absence of bending cracks or other defects (Fig. 2.111). Check the rubber pad chain guide on the absence of excessive wear. If necessary, replace the chain guide.
Pro1verka timing chain Check the circuit elements (plugs and plates) for wear. Replace the chain if excessive wear.
Setting Install the hydraulic lifters into place.

|
Align the timing chain sprocket with the camshaft intake and exhaust valves, as shown in Figure 2.113.
Apply engine oil to the camshaft bearing neck, then install the camshaft in place (Fig. 2.114).
| Fig. 2.115. The identification marks on the bearing caps
|
Install the camshaft bearing caps. The identification marks on the bearing caps are designed to identify the location of the cover (the side of the intake / exhaust valve) (Fig. 2.115). I: intake camshaft. E: exhaust camshaft.

|
With a special tool (mandrel seal installer 09221-21000 Camshaft) press-fit the camshaft oil seal (Fig. 2.117). Make sure that the working edge of an epiploon of a camshaft oiled. Slide the gland on the camshaft sprocket from the timing belt, then with a hammer on the mandrel install the oil seal so that it is flush with the surface.
Place an asterisk (belt) of a camshaft and tighten a bolt of its fastening nominal torque (Fig. 2.118). Tightening torque bolts camshaft sprocket (belt): 80-100 Nm. Align the marks on the crankshaft sprocket and the camshaft with the corresponding adjusting labels and install the piston cylinder ?��1 at TDC compression stroke. Install the cylinder head cover. Tightening torque bolts cylinder head cover: 8-10 Nm. Install the ignition coil assembly, high voltage spark plug wires and the center cover
Install the timing belt, and then when the roller tensioner will tighten the belt, tighten the tensioner mounting (Fig. 2.119). Install the timing belt cover. Tightening torque cover mounting timing belt: 8-10 Nm. Install the water pump pulley and the crankshaft pulley.
