Chronology :
On July 17, 2023, the torque tool used to torque the XT Pro turntable to bearing bolts was found to be out of tolerance. The prior calibration check of that tool was on April 28, 2023.
All machines in process were checked and corrected to have the correct torque. An engineering analysis was completed on October 4, 2023 and determined that the lower torque was inadequate.
On October 5, 2023, the torque tool used to torque the Optima-TC55, Optima-HRX50, and Optima-HRX55 turntable to bearing bolts was found to be out of tolerance.
The prior calibration check of that tool was August 25, 2023. Development of the field fix for the affected models began at that time. The potential unit list was developed by October 9, 2023. Although there are no reports of issues, the decision to recall was made on January 23, 2024.
