Installation

1. Clean the surfaces of the block head, cylinder block, pins and pin holes. If necessary, remove residual sealant with a hardwood scraper. Make sure that no residue of the removed sealant gets into the oil and water channels and threaded sockets.

CAUTION: Make sure that no oil or coolant remains in the threaded sockets of the cylinder block. If this is not done, then, when tightening the head bolts, the cylinder block can be damaged.

2. Using a straightedge and feeler gauge, check the linearity of the underside of the head in the directions shown in the figure.

TECHNICAL DATA, Engine - V8.

3. Install a new O-ring on the cylinder block.

4. Apply STC 50550 sealant to the areas shown in the illustration.

5. Slide a new head gasket over the dowel pins in the cylinder block.

6. With the help of a partner, place the head on the block, making sure that it hits the pins.

7. Replace the washers of the head mounting bolts and screw in new bolts. Tighten the head mounting bolts to 30 Nm in the sequence shown in the figure. Using an angle torque wrench, in the same sequence, tighten the bolts by 80°, and then another 80°.

NOTE: Do not attempt to remove the coating from new bolts.

8. Screw in a bolt of fastening of a shoe of a chain to the left head of cylinders and tighten it.

9. Carefully rotate the camshafts until the cylinder letters and numbers located at the rear of the shafts point upwards.

NOTE: The seemingly incorrect position of the camshafts does not indicate incorrect valve timing.

10. Loosen the bolt securing the mandrel LRT-12-223/4 to the mandrel LRT-12-223/3.

11. Install mandrels LRT-12-223/4 and LRT-12-223/3 on the rear of the camshafts of the left cylinder head and tighten the bolt.

12. Install the mandrels LRT-12-223/5 and LRT-12-223/6 on the left cylinder head and tighten the LRT-12-223/6 using the threaded socket of the spark plug.
