7. Remove the crankshaft pulley and lower plastic cover.
8. Unscrew the glow plugs.
9. Turn the engine crankshaft to a position that allows you to block the elements of the gas distribution system: the holes in the crankshaft pulleys and the fuel filter must be in a position corresponding to the position of the threaded holes made behind the pulleys.
10. Insert locking screws 7.0153 G and screw them in by hand (see fig. The method of fixing the elements of the camshaft drive):
- screw one long bolt into the camshaft pulley;
- screw two short bolts into the fuel pump pulley.
11. Unscrew the bolt securing the camshaft pulley and the central nut securing the fuel pump.
12. Release the drive belt tensioner by unscrewing the nut (1, see fig. Timing belt tensioner adjustment) axle bolt and bolt (2):
- press the tension roller in place (3) with 9.53 mm square wrench (3/8" junior Fac) to compress the spring.
13. Screw in the bolt and nut.
14. Remove the toothed belt. Do not bend the toothed belt. It must not come into contact with oil, water, coolant and grease.
15. Remove the high pressure fuel pump and pump pulley.
16. Remove the camshaft and crankshaft pulleys.
17. Remove the coolant pump and seal (5 bolts).
18. Unscrew the top bolt and nut of the idler axle.
19. Remove the tension roller, pusher and spring.
20. Remove the engine bracket and roller.
21. Remove the fuel pump bracket and the two bracket mounting guide pins on the engine block.
22. Remove the casing of the cylinder head and engine block.
23. Unscrew a bolt and remove a basic element about a collector.
24. Remove the cylinder head cover.
25. Unscrew the camshaft bearing caps one by one and remove the camshaft. Bearing caps are marked 1 to 3 (#1 flywheel side).
26. Loosen the cylinder head bolts "in a spiral", starting outside (reverse order with respect to screwing).
27. Remove bolts and washers.
28. Use the lever to tilt the engine forward to remove the pin.
