# Service bulletin TB1909

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

It has been determined that during the engine assembly process that the locking plate screws shown in Fig.1 for the camshaft and balancer shaft possibly were not mounted correctly on the following models: 2019 690 Enduro R and 2019 690 SMC R. These two screws must be removed, cleaned, have Loctite® 243™ applied and then tightened to a torque of 6 Nm to prevent any possible loosening of the screws.
