Ducati Diavel Service Manual: Refitting the timing belts

Rotate the pulleys on the timing belt driveshaft until the timing mark on the outer roller is aligned with the mark on the clutch-side crankcase cover.

In this condition, the horizontal cylinder piston will be at top dead centre.

Install in the alternator cover seat the tool code 88713.2011 To prevent crankshaft rotation and lock it with the corresponding pin, tighten the m8 screw of the tool to the torque of 20 nm.

Important

To achieve correct timing, the screws (22) securing the pulleys to the hubs must be loose and positioned in the centres of their slots.

Approach the tool code 88765.1623 To insert the pins (f) in the timing shaft seats (g).

Position the tool code 88765.1623 With legend "up" and the arrow facing the cylinder head cover.

First place the pins (f) of the tool with part no. 88765.1623 In the intake side pulley with the wrench of tool with part no. 88765.1623.

Place the pins (f) of tool code 88765.1623 In the exhaust side pulley manually.

Tighten manually the knobs with tool code 88765.1623 Until they stop.

With a torque screwdriver (h) tighten the knob nuts of the tool with part no. 88765.1623 To the torque of 2 nm +/- 10%.

Fit the vertical cylinder timing belt around the camshaft pulleys and pass it behind the idler pulley.

Note

If the used belts are to be refitted, position them in their original direction of rotation and on their original cylinder.

Fit the tensioner pulley (9) and the washer (7) on the pin of the cylinder head.

Apply grease to the tensioner pulley pin threads and to the contact face of the nut (8).

Start the nut (8).

Check the timing belt tension and adjust if necessary as described in the paragraph measuring the timing belt tension values (sect. 6 - 11) Of the vertical cylinder head belt.

Warning

Check the tension on the belt sections (d) and (e) shown in the figure.

Once the required tension has been reached make sure that the nut (8) retaining the tensioner (9) is tightened to a torque of 25 nm (min. 22 Nm - max. 28 Nm) and the screws (22) of the vertical head are tightened to a torque of 10 nm (min. 9 Nm - max. 11 Nm) (sect. 3 - 3, Engine torque settings).

Remove the timing shaft locking tool code 88765.1623 Of the vertical cylinder head.

Carry out timing on the horizontal cylinder head.

Approach the tool code 88765.1623 To insert the pins (f) in the timing shaft seats (g).

Position the tool code 88765.1623 With legend "up" and the arrow facing the cylinder head cover.

Place the pins of tool 88765.1623 In the exhaust side pulley seat (g) manually.

Manually tighten the knobs with tool code 88765.1623 Until they stop.

With a torque screwdriver (h) tighten the knob nuts of the tool with part no. 88765.1623 To the torque of 2 nm +/- 10%.

Fit the horizontal cylinder timing belt around the camshaft pulleys and pass it behind the idler pulley.

Note

If the used belts are to be refitted, position them in their original direction of rotation and on their original cylinder.

Fit the tensioner pulley (9) and the washer (7) on the pin of the cylinder head.

Apply grease to the tensioner pulley pin threads and to the contact face of the nut (8).

Start the nut (8).

Check the timing belt tension and adjust if necessary as described in the paragraph measuring the timing belt tension values (sect. 6 - 11) Of the horizontal cylinder head belt.

Once the required tension has been reached make sure that the nut (8) retaining the tensioner (9) is tightened to a Torque of 25 nm (min. 22 Nm - max. 28 Nm) and the screws (22) of the horizontal head are tightened to a torque of 10 nm (min. 9 Nm - max. 11 Nm) (sect. 3 - 3, Engine torque settings).

Remove the timing shaft locking tool 88765.1623 Of the horizontal cylinder head.
