Refitting the cylinder head assemblies
Warning
To prevent oil leaks in the contact area between cylinders and crankcase, each time the head is removed, cylinder and piston must be removed as well to clean the mating faces of crankcase and cylinder and restore the worn gaskets and O-rings and apply again sealing compound.
Before fitting the head, check that the gasket is fitted on the mating surface between head and cylinder.
When fitting the gasket, side (L) with the stamped part no. (M) must be in contact with the cylinder head.
Lower the cylinder head carefully over the thru bolts. Take care not to damage the threads.
Apply specified grease on the underhead of nuts (1) and on the thru bolt thread.
Fit the special washers (2) and polygonal nuts (1) onto the cylinder head thru bolts.
Screw the polygonal nuts (1) on the thru bolts following a cross pattern using tool no. 88713.2676 together with a torque wrench.
Apply a snug torque of 20 Nm to nuts (1), a pre-tightening to a torque of 40 Nm (Min. 38 Nm - Max. 48 Nm) and a tightening to a torque of 60 Nm (Min. 57 Nm - Max. 63 Nm).
Refit the intake manifolds (Refitting the intake manifold and water union).
Refit the timing belts (Refitting the timing belts) and the timing belt external covers (Refitting timing belt external covers).
Refit the exhaust system (Refitting the exhaust system).
Refit the water radiator on the engine (Refitting the water radiator).
Refit the cooling system hoses and unions on the engine block (Refitting the cooling system hoses and unions).
Refill the cooling system (Changing the coolant).
Refit the injectors on the intake manifolds and the supply system.
Refit the blow-by and the oil breather pipe, the throttle body (Refitting the throttle body) and the airbox (Refitting the airbox).
Refit the fuel tank (Refitting the fuel tank).
Refit the side fairings (Refitting the fairings).
Refit the seat (Refitting the seat).
