What's wrong?
On 2014-2015 Terex Digger Derrick and Aerial Devices equipment, the turntable bearing is the large rotating joint between the carrier and the boom structure. The carrier is the truck or chassis that supports the equipment. Fasteners clamp that bearing to the carrier and to the aerial device or digger derrick so the upper structure stays fixed while it rotates for power-line work.
In recall 15V163, the affected fasteners are Bowmalloy bolts from affected lots. Terex reported bolt head separation and broken fasteners, while the supplier and an independent lab worked on the root cause. The preliminary suspect is hydrogen induced stress corrosion cracking, a condition where cracking starts inside stressed metal and weakens the bolt until it breaks.
There is no warning sign before failure. An operator should not rely on noise, looseness, or visible movement to detect this defect before a fastener breaks.
