Cylinder assy. and timing system

Removing the cylinder head

Head fitting

- To refit it, carry out the removal operations but in reverse order

- Fit a new gasket between the head and the cylinder

- Make sure the coupling surfaces are perfectly clean

- Place the head on the cylinder and tighten the four stud bolts in two or three stages, tightening one

stud bolt and afterwards the one that is diametrically opposite

- Refit the thermoswitch and fit an adhesive gasket on the thread

- Fit the thermostat and its fixing nut

- Connect the thermoswitch connector and the spark plug tube - Connect the radiator coupling to the

cylinder head

- Connect the coupling from the radiator to the hydraulic pump

- Fill the cooling system reservoir with coolant

- Purge the system by operating on the coolant pump cap

Locking torques (N*m)

Stud bolts:

 

19 Nm

 

Screws

 

6 Nm

 

Thermoswitch

 

10 Nm

- Remove the coolant hose connecting the cylinder

to the water pump

- Use a container to collect the coolant

- Remove the hose from the head to the radiator

- Disconnect the temperature sensor electrical

connector.

- Remove the two M6 screws first and then the four

M7 stud bolts fixing nuts

- Remove the head and its gasket

- Remove any carbon deposits present on the

head being careful not to scratch the coupling sur-

faces

- Use a trued bar to check whether the head cou-

pling surface is flat. Maximum run-out allowed:

0.05 mm
