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.

Refitting the timing belts


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.

Refitting the timing belts


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.

First carry out timing on the vertical cylinder head.

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

Refitting the timing belts


Refitting the timing belts


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.

Refitting the timing belts


Refitting the timing belts


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

Refitting the timing belts


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

Refitting the timing belts


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

Refitting the timing belts


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.

Refitting the timing belts


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).

Refitting the timing belts


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.

Refitting the timing belts


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).

Refitting the timing belts


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).

Refitting the timing belts


Refitting the timing belts


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%.

Refitting the timing belts


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.

Refitting the timing belts


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).

Refitting the timing belts


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).

Refitting the timing belts


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

Refitting the cylinder heads pulleys/fixed tensioners
Check that the keyway on the end of the camshaft is in good condition and without burrs. Fit a woodruff key (b) in the keyway of each camshaft. Fit the pulley (11) on the camshaft, inserti ...

Refitting the timing covers
Locate vertical cylinder external cover (25), horizontal cylinder external cover (3) and central external cover (1) by starting the screws (4). Apply the recommended threadlocker to the screws ( ...

Other materials:

Checking the camshafts and supports
Check the cam contact surfaces for scratches, grooves, steps and waving. Worn cams are frequently the cause of poor timing, which leads to loss of engine power. Place the camshaft between two centres and check the run-out on the areas indicated using two dial gauges. Service limit: 0.1 ...

Renewal of the headlight
Disconnect the headlight connectors (a) from the main wiring (refer to the tables of paragraph "routing of wiring on frame", sect. 6 - 1). Loosen nuts (2) that fix the front optical unit to the bottom yoke, and recover the washers (3). Remove the complete front optical unit by sliding ...

Changing the clutch fluid
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 event of accidental contact wash the affected area with abundant running water. Remove cover (1) and membrane from the clutch fluid res ...
