Withdrawal
1. Set the No. 1 cylinder piston to top dead center on the compression stroke.
2. Remove the drive belt and water pump pulley.
3. Remove the crankshaft pulley and the top and bottom timing belt covers.
4. Slide the tensioner fully towards the water pump and secure the tensioner.
5. If the toothed belt has already been in operation, make a mark with an arrow indicating the direction of its movement so that when the belt is installed, it moves in the same direction.
6. Remove the toothed belt from the toothed pulleys.
7. When loosening the oil pump sprocket nut, first remove the plug on the left side of the cylinder block and insert a screwdriver into the hole to hold the balance shaft in position. The screwdriver used for this purpose must have a shaft with a diameter of 8 mm and must be inserted to a depth of more than 60 mm.
8. Turn away a nut of fastening of a gear pulley of the oil pump and remove its gear pulley.
9. Loosen the right balance shaft sprocket bolt until it can be removed by hand.
10. Remove tensioner «IN» and toothed belt «IN».
Warning. After removing the toothed belt «IN» do not try to loosen the bolt by holding the toothed pulley with pliers, etc.
11. Remove the toothed pulley «IN» from the crankshaft.
12. Carefully check the belt. If there are defects, replace the belt with a new one.
Installation
Timing pulleys and tensioner
1. Install the toothed pulley «IN» on the crankshaft.
Warning. Pay special attention to the location of the flange. If installed incorrectly, the belt may break.
2. Apply a light coat of engine oil to the outer surface of the spacer and install it on the right balance shaft in the direction shown in the illustration.
3. Install the toothed pulley on the right balance shaft and hand-tighten the flange bolt.
4. Install the toothed belt «IN» and adjust its tension.
5. Tighten the right balance shaft sprocket bolt.
- Tightening torque: Toothed pulley bolt - 35-40 Nm.
6. Install the flange and toothed pulley on the crankshaft. Make sure to install in the direction shown in the figure.
Warning. Pay attention to the location of the flange. If installed incorrectly, the belt may break.
7. Install the special spacer and sprocket bolt on the crankshaft, then tighten the sprocket bolt.
- Tightening torque: Crankshaft pulley bolt - 110-130 Nm.
8. Install the toothed pulley on the camshaft and tighten the bolt.
- Tightening torque: Camshaft pulley bolt - 80-100 Nm.
9. Install spacer, tensioner and tensioner spring.
10. Attach end A of the spring to the tensioner bracket.
11. Position end B of the spring on the water pump housing.
12. Establish a gear belt and adjust its tension.
13. Establish covers of a gear belt.
14. Install the crankshaft pulley and tip, then tighten the bolts.
- Tightening torque: Crankshaft pulley bolts - 20-30 Nm.
Timing belt installation sequence
1. Align the timing marks on all toothed pulleys with the matching marks on the front cover.
2. After installing the timing belt «IN» make sure that there is no sagging of its working branch.
3. Install tensioner «IN» so that the center of the pulley is to the left of the mounting bolt and the pulley flange is facing the front of the engine.
4. Align the timing marks on the gear pulley of the right front cover balance shaft.
5. Raise tensioner «IN» for tensioning the toothed belt «IN» so that its working branch is stretched. At this point, tighten the tensioner mounting bolt «IN». When tightening the bolt, take care to prevent the shaft from rotating with the bolt. If the shaft turns, the belt will get too much tension. Tighten the right balance shaft flange bolt.
6. Make sure the match marks match.
7. Make sure that when pressing with your index finger on the center of the working section of the belt, its deflection corresponds to the one shown below.
- Belt deflection - 5-7 mm.
8. Move the tensioner fully towards the water pump and temporarily secure the tensioner.
9. Align the alignment marks on the camshaft sprocket and on the cylinder head.
10. Align the alignment marks on the crankshaft sprocket and on the front cover.
11. Align the alignment marks on the oil pump gear pulley and on the front cover.
12. After aligning the mark on the oil pump pulley with the mark on the front cover, remove the plug from the left side of the cylinder block and insert a screwdriver with a diameter of 8 mm into the hole. If it goes in 60 mm or more, the alignment is correct. If it can only be inserted 25 mm, rotate the oil pump sprocket one turn and align the marks again. Make sure that the screwdriver can be inserted more than 60mm. Keep the screwdriver inserted until the toothed belt installation is complete.
13. Install the toothed belt (the working branch of the belt should not sag); install the toothed belt on the toothed pulleys of the crankshaft, oil pump and camshaft in that order.
14. Loosen tensioner bolt and nut. In this case, the spring will move the tensioner and tension the belt.
15. Inspect the belt section and make sure that the belt is pressed against the pulley.
16. Tighten the tensioner mounting bolt and nut.
First, tighten the bolt located in the slot of the bracket, and then the nut installed on the axis of its rotation. If you tighten the nut first, the tensioner bracket will turn with it and the belt will be over-tensioned.
17. Make sure that the alignment marks of all toothed pulleys are aligned with the corresponding marks.
18. Rotate the crankshaft one turn clockwise.
Warning. Do not rotate the crankshaft in the opposite direction.
19. Loosen the tensioner mounting nut and bolt.
20. Tighten the tensioner nut and bolt.
Tighten the nut and bolt in the order specified in paragraph 16.
21. Make sure the clearance «WITH» between the belt and the sealing line of the lid corresponds to the value given.
- Gap «WITH» - approximately 14 mm.
