Ducati Diavel Service Manual: Refitting the expansion tank

If the support (15) has been removed, place the hose clamps (14) on the bracket (15) orienting them as indicated.

Fully press the pins (a) to block the clamps (14) until pins surfaces (b) are at the same level of the clamps (14) surfaces.

Apply recommended threadlocker to the thread of the screws (18) and insert them into washers (17).

Place the bracket (15), as indicated, on the expansion reservoir (12) and tighten the screws (18) to a torque of 5 nm +/- 10% (sect. 3 - 3, Frame torque settings).

Refitting the expansion tank


Fit the clip (8) on the hose (7).

Insert completely the hose (7) into the lower fitting (d) of the expansion reservoir (12), by orienting it so as the reference (e) of the hose matches with the arrow in relief (f) on the expansion reservoir.

Note

In case of difficulties during insertion of the hose (7) into the fitting (d) it is recommended to apply lubricant suitable for rubber to the fitting.

Orient the clamp (8) as indicated and bring it in correspondence with the area (g) of the hose (7).

Tighten the clip (7).

Refitting the expansion tank


Fit the clip (19) on the hose (20).

Insert completely the hose (20) on the upper fitting (h) of the expansion reservoir (5), so that the straight part (l) of the hose is parallel to the bracket (2) as highlighted by the axes (l) and (m).

Note

The hose (20) side to be inserted in the fitting (h) features the white padprinting (n).

Important

Once the assembly is completed, the hose (20) must be in contact with the internal surface of the hose clamp (1) as indicated.

Note

In case of difficulties during insertion of the hose (20) into the fitting (h) it is recommended to apply lubricant suitable for rubber to the fitting.

Block the hose (20) by means of the clip (19), by orienting it as shown.

Insert

Refitting the expansion tank


Insert the spacer with the collar (10) into the hole of the rubber mounting (11).

Fit the rubber mounting (11) as shown, by starting the screw (9).

Tighten the screw (9) to a torque of 8 nm +/- 10% (sect. 3 - 3, Frame torque settings).

Refitting the expansion tank


Position the tank (12) with its hoses (7) and (20) and the support (15).

Position the pipes inside the clamps (14) and close them.

Tighten the screws (16) to the torque of 8 nm +/- 10% (sect. 3 - 3, Frame torque settings).

If hose (24) had been removed, insert the clip (5) on the hose (24) at the position shown.

Fit the union (3) on the hose (24) and secure it using the clamp (5).

If hose (24) had been removed, insert the clip (5) on the hose (24) at the position shown.

Fit the union (3) on the hose (24) and secure it using the clamp (5).

Note

The union (3) must be oriented so that the groove on hose (24) matches the tab (a) on the hose. Orient the clamp (5) as indicated.

Refit the coolant circuit remote filler (4).

Refitting the expansion tank


Position the union (3) on the frame by tightening the screw (2) to a torque of 5 nm +/- 10% (sect. 3 - 3, Frame torque settings).

Place hose (7) on the union (3) with clip (6) and tighten the latter to a torque of 1 nm +/- 10% (sect. 3 - 3, Frame torque settings).

Insert the hose (7) inside the hose guide (a).

Removal of the expansion tank
Loosen the clamp (6), open the hose guide (a) and slide the hose (7) out of the radiator. Open clamps (14) and release the hoses that pass through them. Loosen the screws (16). Remove ...

Removal of the cooling system hoses and unions
Loosen the clips (21) that secure the radiator/thermostat sleeve (40) and the radiator/plug sleeve (24) to the water radiators. Loosen clips (25) and (43) that secure the breather pipe ...

Removing the valve rocker arms
With the cylinder head in the condition described in the previous paragraph, remove the rocker arms. Unscrew the eight plugs (12) and recover the seals (15). Using an m6 screw, withdraw the shafts (2) of the opening rocker arms (3) on the exhaust and intake sides. Remove the openi ...

Checking and adjusting the valve clearances
Note For clarity, the figures show the engine removed from the frame. Move the piston of the cylinder being checked to tdc of the power stroke: in this condition, all the valves are closed and the timing shafts come in neutral position and, therefore, free to rotate; check to the valve cl ...

The battery charging circuit and power distribution
On the diavel, the +15v (key on power) voltage does not come from a conventional ignition key, but from pin 30 of the hands free relay. This relay is switched to closed state by the hands free unit when the latter enables power on for the ignition and engine. The hands free relay receives +30v ...
