Timing gear drive parts: 1 - crankshaft sprocket (2101-1005030); 2 - chain limit pin (2101-1006050); 3 - tensioner shoe (2103-1006090-02); 4 - chain tensioner (21213-1006060); 5 - camshaft sprocket (2101-1006020); 6 - chain damper (2101-1006100); 7 - an asterisk of a drive of the roller of auxiliary units (2101-1006020); 8 - chain (2103-1006040)
Removing
1. We prepare the car for work (see "Vehicle preparation for maintenance and repair").
2. Remove the alternator belt (see "Alternator drive belt - tension adjustment and replacement").
3. Remove the cylinder head cover (see "Cylinder head cover gasket - replacement").
4. Align the mark on the camshaft sprocket with the protrusion on the bearing housing (see "Clearance between valve levers and camshaft lobes - adjustment").
5. Remove the crankshaft pulley (see "Front crankshaft oil seal - replacement").
6. With the help of a chisel, we bend the petal of the lock washer of the camshaft sprocket bolt and unscrew the bolt (see "Camshaft and valve levers - replacement").
7. socket wrench by 10 mm with an extension, unscrew the three bolts securing the crankcase to the camshaft drive cover and loosen the two bolts adjacent to them.
8. With the same tool, unscrew the three nuts and six bolts securing the camshaft drive cover to the cylinder block.
9. We tap the cover with a soft-faced hammer for better detachment from the gasket.
10. Remove the camshaft drive cover and sealing gasket. If there are traces of gaskets on the surfaces of the cover or block, carefully remove them with a knife or other suitable tool.
11. We mark the relative position of the sprocket of the drive shaft of the auxiliary units relative to the cylinder block. This will avoid reinstalling the ignition distributor.
Note: The crankshaft sprocket and cylinder block are marked A, when combined, the pistons of the 1st and 4th cylinders are at top dead center (BMT).
12. Remove the sprocket and chain from the camshaft (see "Camshaft and valve levers - replacement").
13. Remove the timing chain tensioner (see "Timing chain tensioner - replacement").
14. With the help of a chisel, we bend the petal of the lock washer of the bolt for fastening the sprocket of the drive shaft of the auxiliary units.
15. socket wrench by 17 mm unscrew the sprocket mounting bolt. Let's take an asterisk.
16. Key by 10 mm unscrew the restrictive pin and remove the timing chain.
When replacing the chain, it is recommended to replace the sprockets and tensioner shoe.
17. To remove the tensioner shoe with a socket wrench by 17 mm unscrew the bolt of the shoe.
18. Remove the bolt from the hole in the cylinder block and remove the tensioner shoe.
19. With a puller, we press the sprocket from the toe of the crankshaft.
20. Check the condition of the chain links. The rollers must not be chipped, cracked or otherwise mechanically damaged.
Installation
1. Install the sprocket on the toe of the crankshaft.
2. We check the coincidence of the marks on the cylinder block and the crankshaft sprocket.
3. Lubricate the new chain with engine oil and put it on the crankshaft sprocket.
4. Install the chain limit pin.
5. We install an asterisk with a chain put on the auxiliary drive shaft according to the previously applied marks, pulling the leading branch of the chain.
6. Holding the sprocket from rotation, without tightening, we wrap the mounting bolt.
7. We hook the chain with a wire hook and lift it to the camshaft.
8. We put the chain on the camshaft sprocket, and the sprocket on the shaft, ensuring that the marks match.
9. Without tightening, we wrap the camshaft sprocket mounting bolt.
10. "We charge" chain tensioner and, having installed it in its original place, "unloading" (see "Timing chain tensioner - replacement").
11. We turn on the neutral gear and turn the crankshaft two or three turns, paying attention to the coincidence of the marks. Otherwise, repeat the installation of the chain.
12. If the marks match, we turn on the first gear, tighten the bolts of the asterisks and counter them by bending the petals of the lock washers.
13. We wrap the cap nut of the tensioner (see "Timing chain tensioner - replacement").
14. Installation of all removed parts is carried out in reverse order.
15. Check and, if necessary, correct the ignition timing (see "Ignition timing - check and adjustment").
