Vibration damper sprocket
1. Belt; 2. Asterisk in the crankshaft; 3. Tensioner B; 4. Vibration damper sprocket
These engines have 2 toothed belts - a camshaft drive and a vibration damper roller.
Removing
1. Disconnect the battery from the ground.
2. Remove the drive belts, unscrew the bolts and remove the coolant pump and crankshaft pulleys.
3. Remove both front covers and gaskets.
4. Set the piston of the 1st cylinder to the TDC of the compression stroke. From now on, rotation of the crankshaft is not allowed.
5. Mark the direction of rotation on the toothed belt, loosen the tensioner, shift to the cylinder block, tighten the bolts and remove the belt.
6. Remove the camshaft and crankshaft sprockets.
7. Remove the plug on the left side of the cylinder block and insert a screwdriver with a diameter of 8 mm and a length of at least 60 mm, fix the left roller of the vibration damper.
8. Turn away a bolt and remove an asterisk of the oil pump.
9. Loosen the bolt of the right vibration damper roller and remove the vibration damper tensioner B.
10. Remove belt B from vibration damper roller.
11. Check up a condition of a belt, at detection of any defects replace.
12. Check the condition of the sprockets and tensioner. If the teeth are out-of-round, replace the sprocket. Replace the tensioner if a lubricant leak is detected from under the roller seal.
13. Do not wash the roller and sprockets in solvent.
Installation
Correct installation of the right roller bushing
1. Oil seal; 2. Chamfer; 3. Sleeve; 4. Lubricate; 5. Roller
1. Install the vibration damper roller sprocket on the crankshaft.
2. Install on the right roller (if filmed) bushing, sprocket and finger-tighten the bolt (1 - mark on the asterisk; 2 - mark on the case; 3 - notch on the sprocket).
3. Align the marks and put on the roller belt so that there is slack on the side against which the tensioner rests (1 - tensioner; 2 - tension side; 3 - belt B; 4 - bolt; 5 - axis of symmetry of the tensioner roller)
4. Install tensioner B as shown.
5. Raising the roller, tighten the belt and tighten the bolt with a torque of 18 Nm.
6. Tighten the roller sprocket bolt to 35 Nm.
7. Check roller belt tension (deflection 5–7 mm). Readjust if necessary.
8. Install the camshaft belt sprocket, washer on the crankshaft and tighten the bolt with a torque of 119 Nm.
9. Install the sprocket on the camshaft and tighten the bolt to 89 Nm.
10. Install the belt tensioner, spring and secure with a bolt and nut, shifting the tensioner towards the pump. Put on the oil pump sprocket and tighten the nut to 54 Nm.
11. Check the coincidence of the marks on all the sprockets, if necessary, remove the bar that fixes the roller sprocket and tighten the oil pump sprocket.
Insert the rod into place.
Attention! If the bar only enters 25 mm, turn the oil pump 1 turn clockwise.
12. Put on the camshaft belt in the direction of the arrow. Loosen the tensioner bolt and nut and tension the belt.
13. Check the fit of the camshaft sprocket with the belt, the belt can pass with a loosening in the 7–12 o'clock sector. Make sure the belt does not interfere with adjacent parts.
14. First tighten the bolt in the tensioner groove, then the nut (otherwise the belt will break).
15. Check the alignment of all marks and remove the bar. Rotate the crankshaft 1 turn.
16. Loosen tensioner nut and bolt. Tighten the bolt, then the nut to 49 Nm.
17. Check the tension of the belt by squeezing and deflecting it with your fingers, resting against the case.
Deviation should be no more than 14 mm (1 - tension, 2 - tensioner).
18. Next, the assembly is performed in the reverse order. After starting the engine, listen for noises from the belt. If unusual noises are heard, stop the engine and check the installation and tension of the belt.
