Ducati Diavel Service Manual: Adjusting the chain tension

Make the rear wheel turn until you find the position where chain is tightest. Set the vehicle on the side stand. Push down the chain at the point of measurement and release. Measure the distance between the "aperture" upper profile and pin centre.

The read distance must be: 9 to 11 mm.

Adjusting the chain tension


Important

If the drive chain is too tight or too slack, adjust it so that tension reading will fall within specified range.

To adjust the tension remove the rear splash guard (sect. 7 - 13, Removal of the swingarm).

Slacken off the two clamp screws (1) that secure the rear wheel hub to the swingarm.

Fit the hook spanner code 88713.1038 Inserting its tooth in the eccentric hub (2).

Rotate the eccentric hub (2) to obtain the correct chain tension.

Turn counter clockwise to tighten the chain; clockwise to loosen (from chain side).

Important

An incorrectly tensioned chain will lead to accelerated wear of the transmission components.

If the screws (1) are removed, lubricate with specified grease underhead and thread, then tighten the screws (1) to the torque of 35 nm +/- 5% (sect. 3 - 3, Frame torque settings) proceeding with sequence 1-2-1.
