McNeilus Truck & Manufacturing, Inc. (McNeilus) is recalling certain ZF CML12 Ring Gear Carriers, part number 1474124, with serial numbers 5250958, 5250960 and 5250961, sold as field service parts. The ring gear carriers may have cavities located in the toothing, which can lead to premature failure of the drum transmission.
If the drum transmission fails while the vehicle is in motion, the drum may stop rotating and concrete could discharge from the drum onto the road, increasing the risk of crash.
McNeilus will notify owners and will inspect and replace the drum transmissions, as necessary, free of charge. The recall began March 9, 2020. Owners may contact McNeilus customer service at 1-888-686-7278.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
