Locktab for Allison TCDOA-475
This locktab secures fasteners within the Allison TCDOA-475 transmission. It prevents the loosening of nuts and bolts by creating a mechanical lock once the tabs are bent against the fastener faces.

The locktab 6772302 serves as a mechanical locking device within the Allison TCDOA-475 transmission assembly. By bending its tabs against the flat surfaces of a nut and the adjacent component, this part creates a physical barrier that prevents the fastener from rotating. This locking action maintains the integrity of threaded connections that are subject to vibration and dynamic loads during machine operation.
This component is designed specifically for the Allison TCDOA-475 transmission, which is commonly found in heavy machinery such as articulated trucks and cranes. It is engineered to meet the dimensional requirements for internal transmission assemblies. Proper installation of this locking washer ensures that internal fasteners remain secure, which is necessary for the mechanical stability of the transmission system.
In general engineering, locktabs are used in various machinery systems to provide a secondary locking method for bolts and nuts. They are designed to be malleable enough to allow for the bending of the tabs during assembly while maintaining sufficient strength to resist the forces that would otherwise cause a fastener to back out. Using a locktab helps prevent the loosening of critical connections, which could otherwise lead to misalignment or mechanical interference within the transmission housing.
