BMW F650CS: Powertrain
Affects BMW F650CS · 2002 — about 159 vehicles.
The hazard
On certain motorcycles, the hex nut that secures the front drive belt wheel to the gearbox output shaft was torqued to a value less than specification during the vehicle assembly process. As a consequence, the nut could loosen during vehicle operation. If this happens, the belt wheel would itself loosen on the output shaft, resulting in damage to the internal splines of the wheel and to the external splines of the output shafts as the vehicle is operated. Over time, the splines could be damaged to the extent that the output shaft would no longer operate the drive belt, resulting in a loss of drive capability at the rear wheel. Correction: Dealer will secure the front drive belt wheel to the gearbox output shaft by utilizing a new set of components, including a redesigned front wheel pulley. Also the main-shaft splines will be inspected for proper dimension and replaced is it is out of specifications. Note: This recall supersedes recall 2002184
