Refitting the head and timing system components

- Fit the timing chain guide pad.

- Insert the centring dowel between the cylinder

head to the cylinder, fit the cylinder head gasket

and the cylinder head.

- Lubricate the stud bolt threading.

- Tighten up the nuts to an initial pre-torque of 7±1

N·m

- Tighten up the nuts to a second pre-torque of 10

±1 N·m

- Rotate by an angle of 270°

- To carry out the operations described above, fol-

low the tightening sequence in the figure.

- Fit the two screws on the outside of the timing

chain side and tighten them to the specified torque.

N.B.

BEFORE INSTALLING THE HEAD, MAKE SURE THAT THE
LUBRICATION CHANNEL IS CLEAN USING A COM-
PRESSED AIR JET.

Locking torques (N*m)

Timing chain tensioner support screw

11 ÷ 13

- Refit the lower timing chain sprocket wheel on the

crankshaft, with the chamfer facing the insertion

side.

- Loop the timing chain around the sprocket on the

crankshaft.

- Fit the chain tensioner slider from the cylinder

head side.

- Fit the spacer and the screw fastener.

- Tighten the screws to the prescribed torque.

- Fit the pins and rocker arms.

- Lubricate the two rocking levers through the

holes at the top.
