Installing the cylinder head (VAZ-21051)

            0

1. Install the gasket and cylinder head on the cylinder block and tighten in the specified sequence (see Fig. Cylinder Head Bolt Tightening Sequence) in two stages, tighten the cylinder head mounting bolts: first all bolts with a torque of 33.3–41.16 N·m (3.4–4.2 kgf·m), and then 95.94–118.38 N·m (9.79–12.08 kgf·m).

2. Clean the mating surfaces of the cylinder head and camshaft oil seal holder from old gasket residues, dirt and oil. Apply KLT-75TM sealant or a similar TV-1215 sealant to the surface of the cylinder head mating with the oil seal holder "Three Bond".

Attention! The engine may be started 1 hour after applying the liquid gasket.


3. Check if the mark on the crankshaft pulley is aligned with the long mark on the middle protective cover of the camshaft belt drive.

4. Turn the camshaft so that the marks on the pulley and bearing housing are aligned as shown in the figure (see p. 21. subsection 4.4). Without disturbing the position of the shaft, secure the assembled bearing housing to the cylinder head, tightening the nuts in the sequence shown in the figure in p. 22. subsection 4.4.

5. Place the belt on the camshaft pulley. Install the tension roller bracket spring. Smoothly turn the crankshaft two revolutions, keeping the belt under constant tension and not loosening the belt when the shaft stops. Tighten the tension roller bracket mounting bolts.

6. Check that the marks match (see the pictures in p. 21. and p. 24. subsection 4.4). If the marks do not match, repeat the installation of the belt. Adjust the clearance between the camshaft cams and the valve drive levers.



7. Install the cylinder head cover with the gasket and the fuel line bracket. Tighten the cover mounting nuts in the sequence shown in the figure in p. 29. subsection 4.4. Install the upper camshaft timing belt cover.

8. Attach the starter shield and muffler inlet pipe to the exhaust manifold.

9. Connect the hoses to the carburetor, intake manifold, cylinder head cooling jacket outlet pipe and to the heater fluid supply pipe.

10. Attach the throttle linkage to the intermediate lever on the cylinder head cover. Attach the choke cable to the carburetor.

11. Reconnect the removed wires and fill the cooling system with liquid. Check and adjust the ignition timing.
