## ⚠️ Common Signs of Failure

-   Engine cannot be aligned to the shaft within the range of the flexible mounts
-   Bracket faces or mounting holes damaged or corroded
-   Vibration and noise after a conversion put together from mixed hardware
-   Fasteners from two different kits mixed, so the clamping load is wrong
