[Ninjette Newsbot]

Ducati is recalling the 2016-2017 XDiavel because the final drive pulley retaining nut may not have been sufficiently tightened. At the same time, a separate problem may be causing side stands to fail, though no official recall has yet been called for that issue. The final drive pulley recall affects 1,433 units in the U.S.

According to documents released by the National Highway Traffic Safety Administration, the retaining nuts were tightened to 186 Nm which may not be enough to maintain sufficient axial preload for the pulley. If the retaining nut loses axial preload, the belt primary drive pulley may spin on the countershaft, causing a loss of power delivery to the rear wheel.

The problem first came up in June with a field report from the U.S. regarding a belt primary drive wheel spinning on the countershaft. From July to August, Ducati received 13 more field reports (including four from the U.S.). Ducati opened an investigation and on Sept. 12 began worldwide recall procedures.

Ducati dealers will install a new washer made with a harder material while increasing the torque on the retaining nut to 250 Nm.



Though no recall has been announced yet, the documents released by NHTSA indicate a separate problem with the side stand lower fastening screw also lacking sufficient torque. The screws were tightened to 42 Nm which may not be enough to secure the side stand plate.

Should the screw become too loose, the side stand plate may deform and break under the weight of supporting a parked XDiavel. A loose screw may also damage the stand sensor switch, potentially causing the engine to stall.

The side stand issue was first reported in June with two field reports out of Europe of XDiavels falling over while parked. In July and August, Ducati received nine more reports including two from the U.S.

Ducati dealers will replace the lower side stand plate fastening screw with a new, higher strength screw. This new screw can be tightened up to 65 Nm and can be used with a stronger strength threadlock.
