## NHTSA's summary

This Technical Service Bulletin describes the verification and resolution of under\-torqued bolts on the stator backing plate of certain generator sets. Affected generators may not show any physical symptoms initially. However, if the bolts are left under\-torqued, they may become free and cause damage to the alternator, potentially resulting in a generator failure.
