Disassembly
1. Remove the top cover of the camshaft drive (see fig. Camshaft Drive Parts).
2. Loosen the mounting bolts and remove the water pump pulley.
3. Install the piston of the 1st cylinder in the TDC. compression stroke (both valves are closed). The mark on the crankshaft pulley must be aligned with the arrow on the lower camshaft drive cover.
4. Loosen the four bolts and remove the crankshaft pulley.
5. Remove the lower camshaft drive cover.
6. Loosen the nut securing the belt tensioner and turn the eccentric shaft of the belt tensioner counterclockwise with a wrench to loosen the belt tension.
7. Remove the belt from the gears of the crankshaft, camshaft and intermediate shaft and from the tensioner of the tensioner.
8. Loosen the nut and remove the tensioner.
9. Loosen the bolt and remove the intermediate shaft gear, remove the key.
10. Loosen the bolt and remove the crankshaft gear, remove the key.
11. Loosen the bolt and remove the gear from the camshaft, remove the key.
12. Loosen the bolts and remove the rear camshaft drive cover.
Assembly and adjustment
1. Install rear camshaft cover and tighten the mounting bolts.
2. Insert the key into the groove on the crankshaft and install the gear. Apply sealant to the thread of bolt 14, screw in the bolt with washer and tighten to 200 Nm (20.0 kgf·m).
3. Insert the key into the groove on the camshaft, install the gear wheel, screw in the bolt with washer and tighten to 80 Nm (8.0 kgf·m). The mark on the gear wheel must align with the upper plane of the cylinder head cover gasket on the left side of the engine.
4. Insert the key into the groove of the intermediate shaft, install the gear wheel, screw in the bolt 12 with the washer and tighten to 80 Nm (8.0 kgf·m).
5. Install the camshaft drive belt tensioner.
6. Temporarily install the pulley 4 of the crankshaft on the gear wheel 13. The piston of the 1st cylinder must be at TDC. Turn the countershaft gear 11 so that the mark on it aligns with the mark on the crankshaft pulley 4 as shown in the figure.
7. Put on belt 9.
8. Turn key 3 (see fig. Adjusting and checking the tension of the camshaft drive belt) belt tensioner 1 5 clockwise to pre-tension the belt. Check that the w.m.t. did not move. Rotate the tensioner 1 further clockwise, tensioning the belt 5 so that it can be turned through 90°by grasping it with two fingers in the middle between the camshaft and intermediate shaft. While holding the tensioning mechanism with the key 3, tighten the nut of its fastening with the key 2.
9. Remove crankshaft pulley 4. Install the lower cover 7 of the camshaft drive (see fig. Camshaft Drive Parts).
10. Install crankshaft pulley, tighten bolts 3 to 20 Nm (2.0 kgf·m).
11. Install the water pump pulley.
12. Install the camshaft drive top cover.
