Refitting

Clean the cylinder head and crankcase contact surfaces.

Fit a new cylinder head gasket so that the wording 'ALTO [TOP] printed on the gasket is turned toward the operator.

The cylinder head gasket is of the Astadur type. The material from which these gaskets are made undergoes a polymerization process during the operation of the engine so that they become considerably harder during usage. In order for the polymerization of the gasket to take place it is necessary to:

- keep the gasket in its sealed container until fitting

- not lubricate or get oil on the gasket and the contact surfaces.

Refit the cylinder head.

Fit all the cylinder head bolts.

1. Tighten the bolts (1a) fixing the cylinder head to the recommended torque using the angular tightening tool (1b).

Follow the tightening order shown in the figure during the different stages.

Refitting

Fit a new cylinder head gasket to the cylinder block/crankcase, taking care that it is the same thickness as the old one.

ASTADUR type cylinder head gaskets are fitted.

These gaskets are made from a special material designed to undergo polymerization during the use of the engine. This means that they harden considerably during use.

To ensure the polymerisation process takes place, keep the gasket sealed in its plastic bag and do not take out until ready to fit. Do not lubricate the gasket or contaminate with oil.

Position the cylinder head on the cylinder block, taking care that the camshafts are positioned with the front cams facing outwards (valves closed).

1. Tighten the bolts (1a) fixing the cylinder head to the recommended torque using the angular tightening tool (1b).
