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, inserting the woodruff key in the in the slot (c) in the pulley.
Apply the recommended grease to the threads on the end of the camshaft.
Repeat the procedure on the other camshaft.

Insert the tool code 88713.1806 Into the pulleys to prevent rotation.
Apply the recommended grease to the mating face of the nut (21).
Fit the nut (21).
Carry out the same operations on the other camshaft.
Important
Always fit new nuts on reassembly.

Using the bush supplied with tool with part no. 88713.1806 And a torque wrench, tighten the ring nuts (21) to the specified torque of 71 nm (min. 64 Nm - max. 78 Nm) (sect. 3 - 3, Engine torque settings).

Insert the fixed tensioners (13), with bearings and washers (7), into the cylinder head pins and tighten the nuts (8) to a torque of 25 nm (min. 22 Nm - max. 28 Nm) (sect. 3 - 3, Engine torque settings).

Undo the locking screws (22) of the pulleys, turning them anti-clockwise through 90 +/- 5.
Check that the pulleys have no end float and can rotate freely at all points along the full length of the slots.

Reassembly of the timing pulleys
Refitting the timing beltsOxygen 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 ...
Turn indicators (automatic reset)
The instrument panel controls the automatic reset of the turn
indicators.
After activating one of the two turn indicators, they can be
deactivated using the reset button (12, fig. 12).
If the turn indicator is not "reset" manually, the instrument
panel will automatically switch it ...
Accelerator position sensor (throttle grip)
Introduction
An accelerator position sensor (aps) is mounted on the throttle body of the
diavel, which measures the degree of aperture
of the throttle grip.
The throttle grip is connected to the sensor via two metal cables
The sensor transmits information to the ecu relative to the "torque ...
