HME 1871

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

HME, Inc. (HME) is recalling certain 2019-2021 AF1 and 1871 vehicles. The fuel tubes between the fuel rail and the injectors for cylinders four, five, and six may fatigue and crack, which can result in a high pressure fuel leak.

Risk: A high pressure fuel leak in the presence of an ignition source can increase the risk of a fire.

ELECTRICAL SYSTEM:WIRING

HME, Inc. (HME) is recalling certain 2013-2021 AF1, 1871, and SFO vehicles. Insufficient voltage and/or cracked wiring insulation may cause the aerial controls system to fail.

Risk: Exposed wires can create a shock risk to the vehicle operator.

FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL

HME, Inc. (HME) is recalling certain 2017-2020 Ahrens-Fox model 34 Type 3, Rescue, Pumper, Tanker, Aerial, CommFox, WolfSA Tanker, 1871-SFO, 1871-W, 1871-Spectr, and AF1 fire trucks. The sealing washer may not seat correctly in the pilot boreholes, allowing the high-pressure fuel rail assembly to leak.

Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.

EQUIPMENT:MECHANICAL:BOOM/CRANE/LADDER:MOTOR/HYDRAULIC PUMP

HME, Inc. (HME) is recalling certain 2016-2021 AF1 and 1871 vehicles. The self-leveling function may malfunction, causing the aerial bucket to move beyond the level position.

Risk: Unexpected movement of the aerial bucket increases the risk of an injury.

ELECTRICAL SYSTEM:WIRING:FUSES AND CIRCUIT BREAKERS

HME, Inc. (HME) is recalling certain 2016-2020 AF1, 1871 and SFO emergency vehicles. The fuse box may be missing an O-Ring seal, potentially allowing moisture or contaminants into the fuse box.

Risk: If moisture or contaminants enter the fuse box, the fuse box may overheat or malfunction, increasing the risk of a crash.

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

HME, Inc (HME) is recalling certain 2017-2018 1871 vehicles, equipped with Whelen accessory brake lights. Depending on the specific wiring of the vehicle, the brake lights may falsely illuminate even without the brake pedal being pressed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: If the brake lights falsely illuminate, other drivers could become confused, increasing the risk of a crash.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL

HME, Inc. (HME) is recalling certain model year 2000-2006 1871 emergency vehicles manufactured January 1, 2000, to March 15, 2006. The mechanical springs used to return the accelerator pedal to idle after the driver lifts their foot off the pedal may break.

Risk: If the springs break, the pedal may not return to idle once the driver lifts their foot off the pedal. This unintended acceleration increases the risk of a crash.

ENGINE AND ENGINE COOLING

HME IS RECALLING TWO MODEL YEAR 2011 1871 FIRE TRUCKS EQUIPPED WITH CUMMINS ENGINES. THE V-BAND CLAMP ASSEMBLY USED TO CONNECT THE INLET AND OUTLET CONE SECTIONS TO THE DIESEL OXIDATION CATALYST (DOC) DIESEL PARTICULATE FILTER (DPF) INCLUDE A T-BOLT WHICH CAN FRACTURE AND FAIL WHEN SUBJECTED TO STRESS OR LOAD. A FRACTURE OR FAILURE OF THE T-BOLT MAY CAUSE THE CLAMP TO LOOSEN AND THE INLET OR OUTLET SECTIONS ATTACHED TO THE DOC/DPF HOUSING TO DISCONNECT.

Risk: IF THE INLET OR OUTLET SECTIONS DISCONNECT, HOT EXHAUST GASES CAN VENT PRIOR TO EXITING THE TAILPIPE, CREATING THE RISK OF COMBUSTION AND A FIRE. IF BOTH CLAMPS FAIL, THERE IS A RISK IN SOME APPLICATIONS THAT THE DOC/DPF HOUSING MAY DETACH COMPLETELY, CREATING A ROAD HAZARD.
