Ducati Diavel Service Manual: Starter motor
Power: 0.7 Kw/12 v
Direction of rotation: counter clockwise viewed from power take-off side.
The starter motor is highly compact and reliable and therefore rarely gives any type of problem. In case of troubles, ensure that the starter motor cable terminal is properly tightened under the nut and shows no oxidation. If the terminal is properly tightened and free from corrosion, remove the starter motor and test it under no-load conditions (no load applied to the shaft). Secure the starter motor to a test bench, making sure you do not damage the casing. Use a fully charged 12 v battery for the test. Use battery-motor connection cables which are no longer than 70 cm and with the same cross-section as the cable on the motorcycle itself. Connect the negative terminal of the battery to an unpainted area of the starter motor casing and the positive terminal to its electrical terminal. The shaft of the starter motor should rotate freely and at high speed. Take care not to short-circuit the two cables connected to the battery.
Removing the starter motor
Remove the fixing screw (1) and, if necessary, the insert (2).
Unscrew the fixing screws (3): the lower screw (3) fixes also the ground cable (6). Collect the toothed washer (7) and the washer (8).
Note
The starter motor retaining screws are assembled with threadlocker.
Slide out the starter motor and gasket (5).
Refitting the starter motor
Inspect the condition of the gasket (5) and renew if necessary.
Position the gasket (5) and the starter motor on the crankcase. Start the retaining screws (3) with recommended threadlocker; the lower one (3) with the ground cable (6), the toothed washer (7) and the washer (8). Tighten the retaining screws (3) to a torque of 10 nm (min. 9 Nm - max. 11 Nm) (sect. 3 - 3, Engine torque settings).
Locate the insert (2) (if removed) in the crankcase half, hand tighten the fixing screw (1) and tighten it to a torque of 10 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Place the starter motor/solenoid starter cable (4) and tighten the retaining nut to a torque of 5 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Important
Fill the cap with protective grease before fitting it on the starter motor.

Oxygen sensors
Introduction
An on-off type oxygen sensor (in normal operating conditions, the voltage
generated by the sensors switches between a
value close to 1v and a value close to 0v) is mounted on each of the exhaust
manifold of the diavel.
Each oxygen sensor has its own internal heater, which recei ...
