What's wrong?
On 2015 Terex Advance Front Discharge Concrete mixer trucks, the concrete mixing drum is bolted to a drum drive plate. That plate is the link between the drive system and the drum, so it lets the truck turn the loaded drum while the vehicle is working or moving. The bolts have to hold the drum tight against the plate under vibration and heavy load.
In this recall, those bolts were not tightened enough to create the clamp force needed to keep the joint secure. With insufficient clamp load, the hardware can loosen as the drum turns and the truck vibrates. If the joint keeps losing grip, the drum can separate from the drum drive.
Before failure, an owner or operator can see loose hardware or missing hardware around the drum mounting area. The warning sign is not dependable, so the truck also can reach failure without an obvious visible clue.

What's the safety risk?
Improperly tightened bolts can let the drum separate from the vehicle, increasing the risk of injury or a crash. Loose or missing hardware is the warning sign to watch for, but separation can happen without a clear sign first. Schedule the repair soon and avoid using the vehicle if hardware looks loose or missing. Repair is free at any franchised Terex Advance dealer.
