  • Page 66: Filling The Brake System With Fluid

    Maintenance operations Connect a commercial brake bleeder to the front brake calliper bleed valve (5) or rear brake calliper bleed valve (8). Note Follow the manufacturer's instructions when using a commercial brake bleeding tool. Open the bleed valve and pump with the bleeding tool until no more fluid emerges. If you do not have a brake bleeding tool available, attach a length of transparent plastic tubing to the front calliper bleed valve (5) or rear calliper bleed valve (8) and immerse the other end of the tubing in a container on the floor containing old brake fluid.
  • Page 67 Maintenance operations Brake fluid is corrosive and will damage paintwork. Avoid contact with eyes and skin. In the case of accidental contact, wash the affected area thoroughly with plenty of running water. Refill the tanks (2) and (7) with specified oil (Sect. 3 - 2, Fuel, lubricants and other fluids) taken from an intact container.
  • Page 68: Changing The Clutch Fluid

    Maintenance operations If you do not have a brake bleeder available, connect a length of transparent plastic tubing to the bleed valve as outlined in the draining procedure.

  • Page 69 Maintenance operations Attach a length of transparent plastic tubing to the bleed valve (4) and insert the other end of the tubing in a container placed on the floor. Siphon off the fluid from the reservoir (2). Fill the tank (2) with new oil up to the MAX mark. Operate the clutch lever two or three times until the circuit is pressurised.
  • Page 70: Draining The Clutch Hydraulic Circuit

    Maintenance operations Draining the clutch hydraulic circuit Warning Clutch fluid will damage painted surfaces if spilled on them. It is also very harmful if it comes into contact with the skin or with the eyes; In the case of accidental contact, wash the affected area thoroughly with plenty of running water. Remove the dust cap to expose the bleed valve (4).
  • Page 71: Filling The Clutch Circuit

    Maintenance operations ± Refit the cap, tightening the retaining screws (5) to a torque of 10 Nm 10% (Sect. 3 - 3, Frame torque settings) in the sequence 1-2-3-1. ± Tighten the bleed valve (4) to a torque of 4 Nm 10% (Sect.

  • Page 240 System components The ECU controls injector opening by feeding current to the coil of an electromagnet which creates a magnetic field to attract the armature, thereby generating fuel spray. If we take the physical characteristics of the fuel to be constant (viscosity, density), as well as the injector delivery and pressure head (controlled by the fuel pressure regulator), the amount of fuel injected depends on the duration for which the injector is open.
  • Page 241 System components The stepper motor simultaneously controls two by-pass ports having an air flow capacity of around 6 kg/h. The by-pass ports with adjuster screws are present because it is necessary to balance the air flow to the two cylinders. In order to compensate for the quantity of supplementary air supplied by the stepper motor and consequently deliver the correct amount of fuel, the ECU converts the stepper motor steps into angular degrees of the throttle: this system means that opening the stepper motor is equivalent to opening the throttle.

This coupling exploits the axial component of driving torque (bike accelerating) or reverse-acting torque (clutch disengaged) to produce servo-assistance in the former case and prevent rear wheel slip in the latter.

Insert the 1ª- 4ª e 2ª- 3ª speed selector forks (B) in their respective channels in the driven gears of the secondary shaft. Note The two selector forks are identical.
  • Page 673 Apply a uniform and continuous bead of DUCATI liquid gasket to the mating surfaces of the crankcase halves, going around all the holes as shown in the figure.
  • Page 674 Crankcase assembly: crankcase halves Bring the crankcase halves (3) and (16) together, tapping with a rubber mallet in the area of the shafts if necessary. Prepare the crankcase screws and insert them in the alternator-side crankcase half (3); note that the screws are of different lengths.
  • Page 675 Crankcase assembly: crankcase halves Check that the crankshaft can be turned with a certain amount of interference with the main bearings (the crankshaft should have a pre-load of 0.15 to 0.20 mm); check also that all the parts you have fitted are free to rotate or move correctly.

The cylinder head diameter must be within the specified values (Sect. 3 - 1.1, Cylinder/Piston). It is preferable to use crankshafts and connecting rods of the same size class. Renewal of the connecting rod bearings It is good practice to renew the bearings (7) each time the engine is overhauled.
