What's wrong?
The chute swing motor on the 2021 Terex Advance Front Discharge Mixer turns the discharge chute so wet concrete goes where the operator directs it. A small shaft key fits between the motor output shaft and the gearbox connection. The set screw holds that key in place, so motor movement transfers cleanly to the chute instead of slipping.
On these mixers, the shaft key and set screw were not installed correctly during assembly. When the set screw is missing or loose, the key can fall out of the output shaft. Once that happens, the swing motor no longer has a solid mechanical link to the chute, and the chute can move without the operator intending it to move.
The warning sign is in the chute swing function. The chute can fail to turn clockwise or counterclockwise when commanded, or it can work only sporadically.
Who's affected?
The affected equipment is the keyway and set screw used on the mixer.
