2016 MCNEILUS BRIDGEMASTER V MIXER

FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY:PRESSURE RELIEF DEVICES

McNeilus Truck & Manufacturing, Inc. (McNeilus) is recalling certain 2013-2018 Bridgemaster Mixer, Standard Mixer, Model 49 Autoreach Side Loader, Model 48 Zero Radius Side Loader, Model 78 Meridian Front Loader, Model 29 Atlantic Front Loader, Model 87 Contender Front Loader, Model 42 Manual Automated Side Loader, Model 16 3.5 yard TG Rear Loader, Model 11 Heavy Duty Rear Loader, Model 66 40.60 Split Body Rear Loader, Model 10 Standard Rear Loader, Model 12 Tailgate Tag Axle Rear Loader, and Model 13 High Compaction Rear Loader vehicles. The vehicles are powered with compressed natural gas (CNG) and are equipped with pressure relief devices (PRD) that may not function as designed, failing to vent a buildup of pressure, such as could occur if the CNG tank was exposed to fire.

Risk: If the PRD does not activate in the event of a buildup of pressure, the CNG tank may explode, increasing the risk of fire and injury.

FUEL SYSTEM, OTHER

McNeilus Truck & Manufacturing, Inc. (McNeilus) is recalling certain 2016-2018 McNeilus Meridian Front Loader, Atlantic Front Loader, XE Rear Loader, Bridgemaster Mixer, Standard Mixer, and Oshkosh S-Series vehicles, equipped with certain MPVE-250 One-Turn Valves (OTV) on the CNG fuel tanks. If the valve knob is turned more than one turn, the valve's snap ring may fail and the valve stem may forcibly eject from the valve body.

Risk: The forcible ejection of the stem may increase the risk of injury to those nearby. Additionally, the unintended release of CNG can increase the risk of a fire.

EQUIPMENT

McNeilus Truck & Manufacturing, Inc. (McNeilus) is recalling certain 2008-2018 Bridgemaster V concrete mixers equipped with an optional composite material hydraulic tank. The filler neck check valve may seal the tank too tightly, causing the tank to overpressurize and possibly rupture.

Risk: If the tank ruptures it may cause hydraulic fluid to spill. The ruptured tank can cause injuries from plastic debris. The spilled hydraulic fluid could be hot which could cause burn injuries. If the vehicle is on the road when the tank ruptures, the tank pieces or spilled hydraulic fluid may cause a road hazard which could increase the risk of a crash.

FUEL SYSTEM, OTHER:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS

McNeilus Truck & Manufacturing, Inc. (McNeilus) is recalling certain 2014-2016 Standard (REL-10), Heavy Duty (REL-11), Extra Compaction (XC/REL-13), 3.5 yd Tag Axle (TG/REL-16), Atlantic Front Loader (FEL-29), Zero Radius (ZR/ASL-48), AutoReach (AR/ASL-49), Pacific Ultra Front Loader (FEL-76) and Pacific Full Eject Front Loader (FEL-87) refuse trucks, and Bridgemaster(BMV) and Standard (STD) concrete mixers, equipped with Cummins ISX12G compressed natural gas (CNG) engines. These vehicles may have been built with an incorrect fitting to connect the low pressure CNG hose to the CNG fuel filter.

Risk: The incorrect fitting may result in a CNG leak, which in the presence of an ignition source, may increase the risk of a fire. Additionally, the hose may disconnect from the filter and result in an engine stall, increasing the risk of a crash.

BACK OVER PREVENTION: BACK-UP ALARM

McNeilus Truck & Manufacturing, Inc. (McNeilus) is recalling certain 2016-2017 Bridgemaster V concrete mixers, equipped with both FLEX Controls and an optional broadband backup alarm. The backup camera display may shut off and the alarm may stop sounding if the truck is in reverse for an extended period of time.

Risk: If the backup alarm stops emitting the alarm sound when the truck is still reversing, others may not be alerted that the truck is backing up, increasing the risk of personal injury.
